[c-nsp] ASR903 Service instance MTU

[Spyros Kakaroukas]

Hi,

You are correct. IIRC, changing the MTU on the pseudowire, changes just what
you report as the MTU of the AC. Usually the parser will prevent you from
doing something that won't work, or fix it for you, but I don't like to
depend on that. Either way, you will have to at least increase the MTU on
the ACs.

My thoughts and words are my own.

Kind Regards,

Spyros

Thanks Lukas
What am facing actually is that I got a request from my customer to raise
the MTU for all his L2VPN connections (VFI,XCONNECT) AM afraid if I raised
the MTU on the pseudowire interface while the physical interface MTU is
still 1500 to cause an issue
