MikroTik RouterOS v2.9 Reference Manual page 230

unpacking ( none | simple | compress-all | compress-headers ; default: simple ) - specifies the
unpacking mode
• none - accept only usual packets
• simple - accept usual packets and aggregated packets without compression
• compress-headers - accept all packets except those with payload compression
• compress-all - accept all packets
Notes
Level of packet compression increases like this: none -> simple -> compress-headers ->
compress-all.
When router has to send a packet it choses minimum level of packet compression from what its own
packing type is set and what other router's unpacking type is set. Same is with aggregated-size
setting - minimum value of both ends is actual maximum size of aggregated packet used.
aggregated-size can be bigger than interface MTU if network device allows it to be (i.e., it supports
sending and receiving frames bigger than 1514 bytes)
Example
To enable maximal compression on the ether1 interface:
[admin@MikroTik] ip packing> add interface=ether1 packing=compress-all \
\... unpacking=compress-all
[admin@MikroTik] ip packing> print
Flags: X - disabled
# INTERFACE PACKING
0 ether1 compress-all
[admin@MikroTik] ip packing>
