Neighbor advertisementinterval

To set the minimum interval in the sending of BGP routing updates, use the neighbor advertisement-interval router configuration command.

■ neighbor {ip-address | peer-group-name} advertisement-interval seconds To remove an entry, use the no form of this command.

■ no neighbor {ip-address | peer-group-name} advertisement-interval seconds Syntax Description

If a BGP peer group is specified by using the peer-group-name argument, all members of the peer group will inherit the characteristic that is configured with this command.

You can examine the currently configured BGP advertisement interval with the show ip bgp neighbors command. The advertisement interval is defined for a specific neighbor in a specific BGP address family. Actual values of the advertisement interval are therefore stated under the specific address-family portion of the neighbor output. The default timer for EBGP is 30 seconds. After the parameter was changed in the example shown in the figure, the timer switched to 15 seconds.
