Hello all,
I would like to force certain prefixes over a directly connected interface using statc bfd routes.
Unfortunately, the bfd session does not come up, and so aren't the static routes.
The softare on both routers is (ASR 9904) is 5.3.4.
config is as follows:
bfd
interface TenGigE0/0/0/0
!
multipath include location 0/0/CPU0
multipath include location 0/1/CPU0
!
interface TenGigE0/0/0/0
description 12 vrf abc zu pezib11
cdp
vrf abc
ipv4 address 1.1.9.3 255.255.255.254 / ipv4 address 1.1.9.2/31 on the other box
flow ipv4 monitor FM sampler FS ingress
router static
vrf abc
address-family ipv4 unicast
10.10.10.0/24 TenGigE0/0/0/0 1.1.9.2 bfd fast-detect minimum-interval 50 multiplier 5 tag 10
Does any one have a hint what I am missing?
Many thanks, and kind regards,
Ilona

hi Ilona,
I suppose you do have IP connectivity between the two endpoints. Can you share the interface and protected static route config from both devices? You are probably missing the static route on the peer device. BFD on IOS XR always requires a client (unlike the classic IOS). See https://supportforums.cisco.com/docs/DOC-33907.

Hi Aleksandar,
quite correct, thanks a lot!
I don't need any bfd statics back, so have configured a dummy one. the bfd session came up immediatly.
Many, many thanks,
Ilona
