Bidirectional Forwarding Detection for BGP

I have just one note here. BFD can’t be enabled simultaneously with NSF for BGP. Even for other protocols, extreme care should be taken while implementing BFD with NSF. Depending on the platform, there may be enough of a traffic outage during the switchover to cause BFD to prematurely signal a link failure. When BFD is running on the RP, some platforms are not able to detect a switchover before the BFD protocol times out; these platforms are referred to as slow switchover platforms.
