New page

{{Versions|v3, v4}}

== Overview ==

MetaRouter is a new feature in RadioOS 4.0 beta 1 and RadioOS v3.21

Currently MetaRouter can be used on certain CableFree hardware. Please check for latest support information

== Requirements ==

Each Metarouter instance uses the same amount of resources as a stand-alone RadioOS installation. It means that you need a minimum of 24MB of RAM for each RadioOS virtual machine plus memory for the MetaROUTER host itself. It is suggested to have more than 24MB memory available for each Metarouter. Upcoming RadioOS versions will have ability to run virtual machines with less than 16MB per machine.

{{ Note | ''It is possible to run other virtual machines with less than 24MB RAM per machine if the virtual operating system is OpenWRT. The 24MB limitation is only for virtual RadioOS installations.'' }}

Currently on one host you can create up to '''8 virtual machines''' and up to '''8 virtual interfaces'''. Workaround to have more than 8 interfaces in total is to use VLANs. In future versions it will be possible to add up to 16 virtual machines.

Also it is not possible to use external storage devices (Store) in the metarouter virtual devices.

== Where it can be used? ==

The MetaRouter function is useful for allowing clients or lower-privilege users access to their own 'router' and config to configure as they like, without the need for a complete second router, or giving them access to the main router configuration.

For example; a WISP can create a virtual router for the clients ethernet port allowing them to define their own firewall settings, while leaving the WISP's wireless settings untouched.

== Creating a Metarouter==

[admin@RB_Meta] /metarouter> add name=mr0 memory-size=32 disk-size=32000 disabled=no
[admin@RB_Meta] /metarouter> print
Flags: X - disabled
# NAME MEMORY-SIZE DISK-SIZE USED-DISK STATE
0 mr0 16MiB 0kiB 377kiB running

As you can see, creating virtual router is quite easy, you just have to specify name of the router, how many RAM will be allocated for it and disk size that will be used by virtual router. Explanations of all other properties are available in [[#Reference | reference manual]].

''Note: * be careful when using dynamic HDD size for metarouters, a proxy could fill up all your hosts storage!''

==== Example with no settings ====

If you will add a new metarouter without specifying any parameters, it will be added with Dynamic HDD size, and 16MiB of RAM:

[admin@RB_Meta] /metarouter> add name=mr1
[admin@RB_Meta] /metarouter> print
Flags: X - disabled
# NAME MEMORY-SIZE DISK-SIZE USED-DISK STATE
1 mr1 16MiB 0kiB 3kiB running

== OpenWRT as virtual machine ==

Starting from v3.24 and v4.0beta3 MetaROUTER has the ability to import custom built images. As an example we will show how to patch and use OpenWRT as the virtual machine.

=== Importing image ===

If you don't have any specific needs, you can import our prebuilt OpenWRT image, which is downloadable [http://www.CableFree.com/download/metarouter/openwrt-mr-mips-rootfs.tgz MIPS image], [http://www.CableFree.com/download/metarouter/openwrt-mr-ppc-rootfs.tgz PPC image]. Upload openwrt image to the router and import it by ''import-image'' command:

[admin@CableFree] /metarouter> import-image file-name=openwrt-mr-mips-rootfs.tgz
imported: 100%

[admin@CableFree] /metarouter> print
Flags: X - disabled
# NAME MEMORY-SIZE DISK-SIZE USED-DISK STATE
0 mr1 16MiB unlimited 7383kiB running

As you can see OpenWRT is running, now you can start configuration process, which is explained in sections [[#Adding_Interfaces|below]].

=== Building your own OpenWRT image ===

If you are not satisfied with our prebuilt version of OpenWRT, then you can build and use your own image.

First step is to install ''svn'' and get the latest source code from openwrt.org

{{Note|Patch 1.2 was made against older kernel then in current trunk and some extra steps should be taken to apply it to OpenWRT. For example r29684 can be used without modifications}}

svn checkout -r 29684 svn://svn.openwrt.org/openwrt/trunk/

Now you have to patch downloaded source with our [http://www.CableFree.com/download/metarouter/openwrt-metarouter-1.2.patch patch]

{{ Note| Patch v1.2 adds newer kernel support which makes it possible to compile with latest OpenWRT revisions. This patch also adds PowerPC support (ability to run OpenWRT image on RB1000 and RB1100). }}

<pre>
cd trunk/
wget http://www.CableFree.com/download/metarouter/openwrt-metarouter-1.2.patch
patch -p0 <openwrt-metarouter-1.2.patch
</pre>

When source is patched, you have to set up configuration options

make menuconfig

Go to Target System menu and choose ''CableFree MetaROUTER MIPS'' or ''CableFree MetaROUTER PowerPC'' from the list depending for which platform you are building the image.

[[image:snapshot2.png]]

Other options depends on what is your requirements (include for example IPv6 and ppp support or not), you can also stick with defaults.

If you see any error messages while trying to launch ''menuconfig'', like

Build dependency: Please install ncurses. (Missing libncurses.so or ncurses.h)

It means that required libraries are not installed, check the output and install all required libraries.

When you are done with build configuration, type
make

It will take a while to build everything so you can go and have a cup of tea.

After the build process is done, upload newly built image to the router and import it as described in [[#Importing_image|section above]].

{{Warning|On newer GCC versions you may be required to add this patch from OpenWRT [https://dev.openwrt.org/attachment/ticket/12005/stdio.patch]}}

For more options and build instructions look in [http://kamikaze.openwrt.org/docs/openwrt.html#x1-410002.1.1 OpenWRT's documentation]

== Adding Interfaces ==

First, you need to add a new interface to your virtual router. This is done in the interface menu.

The interface command has the following options:
[admin@CableFree] /metarouter> interface add
comment disabled dynamic-mac-address type virtual-machine
copy-from dynamic-bridge static-interface vm-mac-address

Description of each option can be found in [[#Interface | reference manual]].

Let's add one interface:

[admin@CableFree] /metarouter> interface add virtual-machine=mr1 type=dynamic

On the '''host''' physical router the interface appears as a virtual interface:
[admin@CableFree] > /interface print
Flags: D - dynamic, X - disabled, R - running, S - slave
# NAME TYPE MTU
8 R ether9 ether 1500
9 R test bridge 1500
'''10 DR vif1 vif 1500
'''

== Connecting to the virtual machine ==

To connect to your virtual machine, use the console command:

/metarouter console 0

You will see your newly added virtual interface here:

[admin@mr0] > interface print
Flags: D - dynamic, X - disabled, R - running, S - slave
# NAME TYPE MTU
0 R ether1 ether 1500

To disconnect from the metarouter virtual machine console, hit '''CTRL + A''' and then '''Q''' to Quit back to your '''Host''' console (if you are using minicom, hit '''CTRL + A''' twice):

[admin@CableFree] >
[Q - quit connection] [B - send break]
[A - send Ctrl-A prefix] [R - autoconfigure rate]

Q

Welcome back!

== Configuring a virtual network ==

Right now you saw that the virtual interface is visible in the '''Host''' ''Interfaces'' menu as ''vif1'' and also in the '''metarouter ''' ''interfaces'' menu as ''ether1''. You can add an IP address on both interfaces, and set up networking. Creating a bridge between the virtual interface and a physical interface allows traffic to pass.

== Configuration examples ==

=== Creating isolated Metarouter for client ===

This Example will show how to use Metarouter feature to create a isolated router on top of the WISP client site router. The setup for the example is shown on the diagram below:

1. Adding a Metarouter for client:
[admin@RouterGW] /metarouter> add name=client1 memory-size=32
[admin@RouterGW] /metarouter> print
Flags: X - disabled
# NAME MEMORY-SIZE DISK-SIZE USED-DISK STATE
0 client1 32MiB 0kiB 189kiB running
[admin@RouterGW] /metarouter>

2. Adding Metarouter Interfaces for the new created Metarouter:

[admin@RouterGW] /metarouter interface> add virtual-machine=client1
[admin@RouterGW] /metarouter interface> add virtual-machine=client1
[admin@RouterGW] /metarouter interface> print
Flags: X - disabled, A - active
# VIRTUAL-MACHINE TYPE VM-MAC-ADDRESS
0 A client1 dynamic 02:49:E8:55:8E:E8
1 A client1 dynamic 02:16:16:90:EF:0E
[admin@RouterGW] /metarouter interface>

3. Creating a Bridge Interface for bridging metarouter interface together with ethernet interface where the client is physically connected:

[admin@RouterGW] /interface bridge> add
[admin@RouterGW] /interface bridge> print
Flags: X - disabled, R - running
0 R name="bridge1" mtu=1500 arp=enabled mac-address=00:00:00:00:00:00 protocol-mode=none
priority=0x8000 auto-mac=yes admin-mac=00:00:00:00:00:00 max-message-age=20s
forward-delay=15s transmit-hold-count=6 ageing-time=5m

[admin@RouterGW] /interface bridge port> add interface=ether2 bridge=bridge1
[admin@RouterGW] /interface bridge port> add interface=vif2 bridge=bridge1
[admin@RouterGW] /interface bridge port> print
Flags: X - disabled, I - inactive, D - dynamic
# INTERFACE BRIDGE PRIORITY PATH-COST HORIZON
0 ether2 bridge1 0x80 10 none
1 vif2 bridge1 0x80 10 none

4. Adding IP configuration for the new Metarouter interface which will be used for connecting between Metarouter and Metarouter Host system:

[admin@RouterGW] /ip address> add address=10.0.1.1/24 interface=vif1
[admin@RouterGW] /ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 D 10.5.8.68/24 10.5.8.0 10.5.8.255 ether1
1 10.0.1.1/24 10.0.1.0 10.0.1.255 vif1
[admin@RouterGW] /ip address>

5. Connecting to Metarouter using the Console

[admin@RouterGW] /metarouter> console client1

[Ctrl-A is the prefix key]

Starting...
Starting services...

CableFree 3.21
CableFree Login: admin
Password:

[admin@CableFree] > /sys identity set name=Client1

6. Configuring Metarouter to make it easy for client to understand the configuration:

[admin@Client1] /interface ethernet> p
Flags: X - disabled, R - running, S - slave
# NAME MTU MAC-ADDRESS ARP
0 R ether1 1500 02:49:E8:55:8E:E8 enabled
1 R ether2 1500 02:16:16:90:EF:0E enabled
[admin@Client1] /interface ethernet> set 0 name=public
[admin@Client1] /interface ethernet> set 1 name=local
[admin@Client1] /interface ethernet> print
Flags: X - disabled, R - running, S - slave
# NAME MTU MAC-ADDRESS ARP
0 R public 1500 02:49:E8:55:8E:E8 enabled
1 R local 1500 02:16:16:90:EF:0E enabled
[admin@Client1] /interface ethernet>

[admin@Client1] /ip address> add address=10.0.1.2/24 interfae=public
[admin@Client1] /ip address> add address=10.0.2.1/24 interface=local
[admin@Client1] /ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 10.0.1.2/24 10.0.1.0 10.0.1.255 public
1 10.0.2.1/24 10.0.2.0 10.0.2.255 local

[admin@Client1] /ip route> add gateway=10.0.1.1
[admin@Client1] /ip route> print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,
B - blackhole, U - unreachable, P - prohibit
# DST-ADDRESS PREF-SRC G GATEWAY DISTANCE INTERFACE
0 A S 0.0.0.0/0 r 10.0.1.1 1 public
1 ADC 10.0.1.0/24 10.0.1.2 0 public
2 ADC 10.0.2.0/24 10.0.2.1 0 local
[admin@Client1] /ip route>

[admin@Client1] /ip firewall nat> add action=masquerade out-interface=public chain=srcnat

==Known Issues==

===MIPS-BE===

Issues and possible workarounds for MetaROUTER feature on CableFree devices with MIPS-BE architecture

====Random freezing====

Issue has been resolved in RadioOS 6.x

===PPC===
Issues and possible workarounds for MetaROUTER feature on CableFree devices with PPC architecture

====Not enough resources====

Only listed routers are affected: RB1100AH

When attempt is made to create MetaROUTER guest on the router error message is given that there is not enough resources on the router to create guest.

This problem is resolved in 5.12 and later RadioOS releases. If you are using a newer release and still encounter the problem on the router you have to reinstall the router using Netinstall tool.

CableFree device RB1100AHx2 reports similar message, but MetaROUTER feature is not currently supported on this router.

All other routers form this architecture that support MetaROUTER feature are not affected.

Other issues that do not fit the description most probably are caused by RadioOS misconfiguration and does not have a common denominator and have to be checked case by case.
