By default, RIP GR is disabled.

By default, the GR interval is 60

Enabling RIP NSR
Nonstop Routing (NSR) allows the device to back up the routing information from the active RIP
process to the standby RIP process. After an active/standby switchover, NSR can complete route
regeneration without tearing down adjacencies or impacting forwarding services.
NSR does not require the cooperation of neighboring devices to recover routing information, and it is
typically used more often than GR.
IMPORTANT:
A device that has RIP NSR enabled cannot act as GR restarter.
To enable RIP NSR:

By default, RIP NSR is disabled.
RIP NSR enabled for a RIP
process takes effect only on that
process. As a best practice,
enable RIP NSR for each process
if multiple RIP processes exist.
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. 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.
