Configuring BFD for RIP
RIP detects route failures by periodically sending requests. If it receives no response for a route within a certain time, RIP considers the route unreachable. This detection mechanism is not fast enough. To speed up convergence, perform this task to enable BFD for RIP. For more information about BFD, see High Availability Configuration Guide.
RIP supports the following BFD detection modes:
Single-hop echo detection—Detection mode for a direct neighbor. In this mode, a BFD session is established only when the directly connected neighbor has route information to send.
Single-hop echo detection for a specific destination—In this mode, a BFD session is established to the specified RIP neighbor when RIP is enabled on the local interface.
Bidirectional control detection—Detection mode for an indirect neighbor. In this mode, a BFD session is established only when both ends have routes to send and BFD is enabled on the receiving interface.
