EOIP in eiop in eoip

RouterOS General

I use many eoips in my network and some times it doesnt work as good
as I would like to and problem is on setting MTU on interfaces.

A - B - C - D - E - F -G

I have eoip tunnels
C-E
B-F
A-G

on every interface mtu=1500.
and on eoip A-G some packets are losts (>1480).
Should I incerease mtu on some interfaces ? On which ?

you have to decrease MTU on interfaces because EoIP adds overhead, or packets get fragmented if you “insist” on 1500byte packets.
