ASR9K MTU 14 byte adjustment on Ethernet and OSPF

[s.lachica]

Configuring mtu 9230 in ASR9K and mtu 9216 on CE router - will this make the ospf adjacency not go up?

Thanks!

Correct.

Better to use BGP instead.

Thanks.

No, but you have different options:

1. Change the MTU value

2. Maintain the MTU , but adjust the IP MTU on the ASR9K to 9216

3. Configure mtu ignore

Hope this helps,

Jose.
