• interface-id —A routing interface identifier.
•
ip-address —The neighbor’s IPv4 address.

seconds —The minimum time between route advertisement, in seconds.
The range is 0 to 600 seconds.
Default Configuration
The default value is 30 seconds for external peers and 5 seconds for internal
peers.
Command Mode
BGP Router Configuration mode
User Guidelines
RFC 4271 recommends the interval for internal peers be shorter than the
interval for external peers to enable fast convergence within an autonomous
system. This value does not limit the rate of route selection, only the rate of
route advertisement. If BGP changes the route to a destination multiple
times while waiting for the advertisement interval to expire, only the final
result is advertised to the neighbor.
Dell Networking BGP enforces the advertisement interval by limiting how
often phase 3 of the decision process can run for each update group. The
interval applies to withdrawals as well as active advertisements.
