Configuring BGP4 neighbors
The <ip-addr> | <peer-group-name> parameter indicates whether you are configuring an individual
neighbor or a peer group. If you specify a neighbor's IP address, you are configuring that individual
neighbor. If you specify a peer group name, you are configuring a peer group. Refer to
a BGP4 peer group"
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 ASs). The default is 5
for IBGP neighbors (neighbors in the same AS). The range is 0 – 600.
capability orf prefixlist [send | receive] configures cooperative router filtering. The send | receive
parameter specifies the support you are enabling:
•
•
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
NOTE
The current release supports cooperative filtering only for filters configured using IP prefix lists.
default-originate [route-map <map-name>] configures the device to send the default route 0.0.0.0
to the neighbor. If you use the route-map <map-name> parameter, the route map injects the
default route conditionally, based on the match conditions in the route map.
description <string> specifies a name for the neighbor. You can enter an alphanumeric text string
up to 80 characters long.
distribute-list in | out <num,num,...> specifies a distribute list to be applied to updates to or from
the specified neighbor. The in | out keyword specifies whether the list is applied on updates
received from the neighbor or sent to the neighbor. The <num,num,...> parameter specifies the list
of address-list filters. The router applies the filters in the order in which you list them and stops
applying the filters in the distribute list when a match is found.
Alternatively, you can specify distribute-list <acl-num> in | out to use an IP ACL instead of a
distribute list. In this case, <acl-num> is an IP ACL.
NOTE
By default, if a route does not match any of the filters, the device denies the route. To change the
default behavior, configure the last filter as "permit any any".
NOTE
The address filter must already be configured. Refer to

send – The device sends the IP prefix lists as Outbound Route Filters (ORFs) to the neighbor.
receive – The device accepts filters as Outbound Route Filters (ORFs) from the neighbor.
