[c-nsp] Cisco 2821 as an ethernet fed MPLS PE

[Flint, Chris]

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.

Hi Chris,

This link will tell you about the MPLS support (answer = yes, depending):
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6557/prod_white_paper0900aecd8051fbdc.html

And look here for jumbo frame support on 2800 (answer = yes, up to 9000 bytes):

Can anyone comment on the 2821 as an ethernet fed MPLS PE?


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.
