Hello all,
We have the problem that MPLS labled packets are not beeing processed on EHWIC-1GE-SFP-CU if L3PDU + Shim-Header exceeds 1500 bytes
When we move the config exactely to the onboard Interface Gi0/0 it works withoput any problems.
Connection like this:
(MPLS-Network) --- Cisco7301 Gi0/2.1202 --- (P2P-VPLS-Link) --- Gi0/0/0.1202 Cisco2921
Config like this:
Router#sh run | i ^mpls ldp|path-mtu
mpls ldp explicit-null
mpls ldp graceful-restart
mpls ldp tcp pak-priority
mpls ldp session protection
mpls ldp advertise-labels for acl-mpls-ldp-advertise
ip tcp path-mtu-discovery
mpls ldp router-id Loopback0 force
