Hi

Has anybody out  have implemented the PE-PE connection  being backup by
ISDN PRI ? . I experienced very unstable connection with the OSPF adjacency
flapping most of the time and the VPN can never be developed .

Cheers

You should configure the tagswitching MTU in the Fast Ethernet
interfaces to be able to hold the MPLS frame with as many shim headers
as you need. for example 1508 if you want to labels.

mpls mtu 1508

under the interface configuration.
