8.14.4 Configuring a MinRouteAdvertisementIntervalTimer

A proper MinRouteAdvertisementIntervalTimer can be configured to suppress frequent route
changes, improving BGP network stability.
Context
BGP peers use update messages to exchange routing information. Update messages can be used
to advertise multiple reachable routes with the same attributes or withdraw multiple unreachable
routes.
BGP does not periodically update a routing table. When BGP routes change, BGP updates the
changed BGP routes in the BGP routing table by sending Update messages. If a route changes
frequently, to prevent the router from sending Update messages upon every change, set the
interval at which Update messages are sent.
Perform the following steps on a BGP router:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
Step 3 Run:
peer { ipv4-address | group-name } route-update-interval interval
A MinRouteAdvertisementIntervalTimer is configured.
By default, the interval at which Update messages are sent to IBGP peers is 15s, and the interval
at which Update messages are sent to EBGP peers is 30s.
ipv4-address specifies the address of a specific group. group-name specifies the name of a peer
group. The MinRouteAdvertisementIntervalTimer configured for a peer takes precedence over
the MinRouteAdvertisementIntervalTimer configured for a peer group.

NOTE
Setting the Keepalive time to 20s is recommended. If the Keepalive time is smaller than 20s,
sessions between peers may be closed.
Timers set for a specific peer or peer group takes precedence over timers set for all
peers or peer groups.
