Hi,
This is my config
**** Interface config ****
interface GigabitEthernet0/0
description ISP Link
dampening
mtu 1540
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
no ip mroute-cache

interface GigabitEthernet0/0.11

ip ospf bfd
mpls ldp igp sync delay 10
mpls ip
bfd interval 300 min_rx 300 multiplier 3
no cdp enable
end
We are only getting bfd flaps/ospf neighbour down on GigabitEthernet0/0.11
We have checked with ISP & as per them everything is fine
We have also done BER test on the link & no error.
