Advertisement Interval

Use the advertisement-interval command to configure AOS to specify how long the BGP process waits

before sending updates to the neighbor. This command sets the minimum interval between sending updates

to the specified neighbor.

(config-bgp-neighbor)#advertisement-interval <value>

<value> Specifies the advertisement interval in seconds. Range is 0 to 600 seconds.

By default, the advertisement interval is 30 seconds for external neighbors and 5 seconds

for internal neighbors.
