How to do BFD with object tracking between two XR devices?

[Seth Beauchamp]

I am trying to get BFD on a track statement working between two XR devices. I was able to get it working between an XR and an XE device, but not XR to XR. I've tried applying a similar config to both XR devices like i have below:

track 1
type bfdrtr rate 500 debounce 3 Interface Bundle-Ether1 destaddress 10.200.255.1

Any ideas how to get it to work between two XR devices?

Please provide show bfd session detail

Hi,

i was reviewing a few cases and saw an old case stating tracking over bundle was not supported.

is it possible to try this config with a physical interface?

Also i expect to see object tracking as client in show bfd session

Thanks

[Seth Beauchamp]

Yep looks like it works on a non bundled interface. It does indeed show up in show bfd session detail as "object_tracking". Thanks

[Aleksandar Vidakovic]

If both ends of the bundle interface are XR devices (without any L2 in-between), have you considered running BoB and then track the bundle interface status as tracking object? BoB will take the bundle down very quickly in case of any failure. See https://supportforums.cisco.com/docs/DOC-33907.

thanks, i will look into this
