Hi,
Is BFD over a 9000v that hosted by a CRS running 5.3.4 supported?
I have a CRS/9000v connected to an ASR920 that is correctly running BFD with another ASR920, but it won't come up vs the CRS/9000v.
My configuration on the CRS/9000v is:
interface Gi128/0/0/2
description xxxxxxxxx
cdp
mtu 9216
ipv4 address x.x.x.x 255.255.255.252
load-interval 30
router ospf 1000
router-id x.x.x.x
bfd minimum-interval 100
bfd fast-detect
bfd multiplier 3
mpls ldp sync
mtu-ignore enable
maximum paths 8
nsf ietf
timers throttle lsa all 10 100 1000
timers throttle spf 10 100 1000
timers lsa min-arrival 50
router ospf 1000
area 201
!
interface Gi128/0/0/2
bfd minimum-interval 50
bfd fast-detect
bfd multiplier 3
cost 1000
authentication message-digest
message-digest-key 100 md5 encrypted XXXXX
network point-to-point
passive disable
This is what it looks like from CRS side:
RP/0/RP1/CPU0:CRS#sh bfd session

Any ideas? Is there a particular configuration you have to use on BFD over nvsat?
All help is appreciated.
