Configuring BFD for BGP
This section describes the procedure for configuring BFD for BGP single hop and multiple hop, so that BGP is a registered protocol with BFD and receives detection-failure messages about the forwarding path. Implementing BFD for BGP results in fast convergence timings.
Note: BFD is supported for both iBGP and eBGP. All these configurations are for BFD over iBGP. For BFD over eBGP, remote-as (asn) can be modified with remote system (asn) for both single-hop and multiple-hop BFD. The eBGP multiple-hop (hopcount) is configured with the required hop count for eBGP mutiple-hop BFD.
Note: BFD for BGP is supported for both IPv4 and IPv6 addressing.
