2821 works as an MPLS PE, the 10/100/1000 interfaces on 2821 support higher MTU.
If you downsize to a 2811/01, you have to run 12.4(x)T to get a user-settable MTU on the 10/100 interface. Even then you get an error message, but the MTU command is accepted. I'm not sure exactly where support started, but (20)T and (22)T both support it.

This would require a settable MTU on the GigE ports "ie: mtu 1576", and standard support for LDP, MP-BGP, standard L3 VPN support. Spent too much time trolling Cisco site and not finding answers. ------------------------------ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
