Greetings,
I have two questions about building bfd session:
1. As the customer requested, we tried to set bfd multiplier 2 & bfd minimum-interval 5000 on our bgp neighborship, it failed. But we then tried 3 & 500 (refer to the existing bfd setting on our router), the session became UP. We've made sure that the settings by customer is sync to ours. Why can't 2 & 5000 work?
2. It's weird that in "show bfd session", our new built session is under the Src Addr instead of Interface like others (pls see attached picture). I compared the configs of those also configured bfd on BGP, not on static route, there's no obvious difference in their configs. Does anyone know why there are sessions under different field?
Thank you very much.

multiplier is number of missing packet before declare the peer is down
so the packet is missing sure, either packet is face delay or CPU of peer is busy

BFDrouter#show bfd neighbor details
share this for both cases with multi 2 and 3

Hello,
3 is the default. Can you request a 'show bfd' from the customer to make sure that the customer has actually configured 2 ?
