I have a question regarding AToM.
Say I have CE1---PE1----P1----P2----PE2-----CE2
CE1 to PE1 - Ethernet 802.1Q
CE2 to PE2 - FR
To get AToM up and working, would I need to change the mtu on the PE and P routers in the core?
And if so to what value?
What command would I use, if I had to: mtu or mpls mtu?
Thanks for your help.
