==Overview==
IP Packing provides packet packaging service on network links. It allows simple packet aggregation into larger packets and compression of contents of packets.

==Requirements==
Packet packing is part of system package and has to have discovery protocol enabled on interface.

==Configuration==
'''Menu: ''/ip packing'''''

It required to have configuration in two places, both routers should be set up symetrically:
* ''ip packing'' - to enable packet aggregation and/or compression on interface
* ''/ip neighbor discovery''- to enable [[Manual:IP/Neighbor_discovery|discovery]] protocol on the interface

==Packing configuration==

* ''simple'' - do just aggregation of packets
* ''compress-all - do aggregation and attempt to compress headers and payload of packet
* ''compress-headers - do aggregation and attempt to compress headers and leaving payload of packet as is
* ''none'' - send packets as is

|style="border-bottom:1px solid gray;" valign="top"|action it should perform when packet is received on interface packing rule is configured on.
* ''simple'' - unpack received packets from aggregated packet received from interface
* ''compress-all - unpack aggregated packet and uncompress headers and payload of packet
* ''compress-headers - unpack aggregated packet and decompress headers of packet
* ''none'' - do nothing with received packet

{{ Warning|Router should be seen as neighbour of router over interface you want to enable packing on. If in neighbour list there are no entry indicating packing, packing is not working! }}

{{ Note|Packing may increase latency on the link it is configured on! }}

==Example==
Router-A and Router-B are connected with cable with interface ether1 on Router-A and ether3 on Router-B. This example will aggregate packets coming from Router-A, but will leave packets from Router-B intact
On Router-A:
* make sure discovery is enabled
/ip neighbor discovery set ether1 discover=yes
* add packing rule for the interface
/ip packing add interface=ether1 aggregated-size=1500 packing=simple unpacking=none
On Router-B:
* make sure discovery is enabled
/ip neighbor discovery set ether3 discover=yes
* add packing rule for the interface
/ip packing add interface=ether3 aggregated-size=1500 packing=none unpacking=simple
