Configuring BGP4 neighbors
26
For more information, refer to
“Configuring cooperative BGP4 route filtering”
on page 807.
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 BigIron RX 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 749.
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 – 255. The default is 0. If you leave the EBGP TTL value set to 0, the software uses the IP
TTL value.
filter-list in | out
<num,num,...>
specifies an AS-path filter list or a list of AS-path ACLs. The in | out
keyword specifies whether the list is applied on updates received from the neighbor or sent to the
neighbor. If you specify in or out, The
<num,num,...>
parameter specifies the list of AS-path filters.
The router applies the filters in the order in which you list them and stops applying the filters in the
AS-path filter list when a match is found. The weight
<num>
parameter specifies a weight that the
device applies to routes received from the neighbor that match the AS-path filter or ACL. You can
specify a number from 0 – 65535.
Alternatively, you can specify filter-list
<acl-num>
in | out | weight to use an AS-path ACL instead of
an AS-path filter list. In this case,
<acl-num>
is an AS-path ACL.
NOTE
By default, if an AS-path does not match any of the filters or ACLs, the BigIron RX denies the route.
To change the default behavior, configure the last filter or ACL as “permit any any”.
NOTE
The AS-path filter or ACL must already be configured. Refer to
“Filtering AS-paths”
on page 793.
maximum-prefix
<num>
specifies the maximum number of IP network prefixes (routes) that can be
learned from the specified neighbor or peer group. You can specify a value from 0 – 4294967295.
The default is 0 (unlimited).
