strange problem with mpls

Dears

I have one branch connected through MPLS to me

The branch side is ATM to Telco and on my side it's connected to Telco thru Gig ethernet .

interface GigabitEthernet0/3.65
encapsulation dot1Q 3456
ip address 192.168.1.1 255.255.255.252
mpls ip


interface ATM6/0.650 point-to-point
ip address  192.168.1.2 255.255.255.252
  atm route-bridged ip
mpls ip
pvc 0/138
  protocol ip 192.168.1.1 broadcast
  encapsulation aal5snap

I faced a strange problem that I can't ping to IP's on branch side with packet size greater than 500 bytes ,but if disable mpls ip from the interface it's working . Any Clues ?

Re: strange problem with mpls

Hi Harris,

Check MTU configurations on both ends. Also, is it possible to ping the with "mpls ip" configured with default packet size (100 bytes)? I suspect MTU or encapsulation configuration errors.
