Need urgent help.
WXC TOPOLOGY: Hub and Spoke.
WAN Architecture: Hub and Spoke and routing protocol OSPF
ISSUE: PBR is configured for off-path installation as I have single stack group. Due to PBR, traffic is going through WXC tunnel but when WXC fails, traffic is not going through normal routing.
So the FBF you are using on the M-series does not provide for a feedback mechanism. If the WX is removed from the solution, its not the job of WX to tell FBF not to send it traffic.
I think your question is best placed to the IPG / routing forum asking specificically how FBF can detect for blackholes.
