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 1051.
NOTE
The current release supports cooperative filtering only for filters configured using IP prefix lists.
default-originate [route-map <map-name>] configures the Layer 3 Switch 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 Layer 3 Switch 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 “Filtering specific IP addresses” on
page 1033.
ebgp-multihop [<num>] specifies that the neighbor is more than one hop away and that the
session type with the neighbor is thus EBGP-multihop. This option is disabled by default. The
<num> parameter specifies the TTL you are adding for the neighbor. You can specify a number
from 0 through 255. The default is 0. If you leave the EBGP TTL value set to 0, the software uses
the IP TTL value.
