Has anyone setup a working BFD session between cisco ACI and an IOS XR 9K for a directely connected EBGP peer via routed sub interfaces ? min int 50 multiplier 3 on both ACI and on IOS XR. IBGP with BFD between 2 ios xr routers connected to two different border leafs work in multipod setup. IBGP is formed on the loppback addresses. EBPG connection from IOS XR to the border leaf is also up. But as soon as i enable BFD on the bgp l3out and peer connection profile to the XR router and i enable bfd fastdetect under the neighbor config the ebgp session starts flapping because of bfd dampening. Logging shows BFD echo request fails but ping between ACI and IOS XR interfaces works.
