The <ip-addr> | <peer-group-name> parameter indicates whether you are configuring an individual
neighbor or a peer group. If you specify a neighbor IP address, you are configuring that individual
neighbor. If you specify a peer group name, you are configuring a peer group. Refer to “Adding a
BGP4 peer group” on page 1361.
advertisement-interval <num> specifies the minimum delay (in seconds) between messages to the
specified neighbor. The default is 30 for EBGP neighbors (neighbors in other autonomous systems).
The default is 5 for IBGP neighbors (neighbors in the same AS). The range is 0 through 600.
NOTE
The Layer 3 switch applies the advertisement interval only under certain conditions. The Layer 3
switch does not apply the advertisement interval when sending initial updates to a BGP4 neighbor.
As a result, the Layer 3 switch sends the updates one immediately after another, without waiting for
the advertisement interval.
capability orf prefixlist [send | receive] configures cooperative router filtering. The send | receive
parameter specifies the support you are enabling:
• send – The Layer 3 switch sends the IP prefix lists as Outbound Route Filters (ORFs) to the
neighbor.
• receive – The Layer 3 switch accepts filters as Outbound Route Filters (ORFs) from the
neighbor.
If you do not specify the capability, both capabilities are enabled. The prefixlist parameter specifies
the type of filter you want to send to the neighbor.
For more information, refer to “Configuring cooperative BGP4 route filtering” on page 1411.
NOTE
The current release supports cooperative filtering only for filters configured using IP prefix lists.
