Dear Sirs,
I have a RB1100AHx2 as concentrator PPPoE and a lot of tunnel EOIP over a big ospf network. Mikrotik set by default 1480 as MTU. Is it correct use 1480? If is not correct, how much must be and where must I change MTU, because on different message read different MTU. Where must I change the MTU, in pppoe server or on every EOIP interface?
Now pings, going from a simple ospf network to ospf + EOIP network + PPPoE concentrator, increase a lot and I don't understand where I'm wrong.
Thanks in advance for help...
