Cisco ir1101, i cannot ping mpls ipv4 neighbor loopback address through tunnel, it is carrier circuit and have mtu size 1500.
my question is mpls will working on circuit have mtu 1500? because i am planning to run MP BGP and have OSPF between tunnel and mpls enabled.
OSPF, MPLS and MP-BGP is up but i cannot ping my neighbor loopback address from one side by using mpls ipv4 but other side of tunnel i can ping.
