Title: RE: [MPLS-OPS]: IP Routing problem after enabling MPLS?

Do you also have Fast Ethernet Port on this? If yes, whether that allows change of MTU.
Please search CCO & I am sure this limitation & possible resolution must be listed on the site. In Between, I also doubt that "Telenet" would pose any such MTU related issue, being small byte packet(<1500 Bytes]. Normally FTP/SMTP[Transparent or encapsulated in IPSec/GRE] applications face MTU related issues being more then 1500 Bytes[and ICMP blocked in the path]. Please confirm whether PING Packet less then 1400 Bytes continues to go well thru the Network, with MPLS enabled.

Won't take the command:

switch1.ffm4(config)#int gig0/1
switch1.ffm4(config-if)#mtu 1512
% Interface GigabitEthernet0/1 does not support adjustable maximum
