Brocade Communications Systems FastIron X Series User Manual

NOTE
The device applies the advertisement interval only under certain conditions. The device does not apply the advertisement
interval when sending initial updates to a BGP4 neighbor. As a result, the device sends the updates one immediately after
another, without waiting for the advertisement interval.
allowas-in num disables the AS_PATH check function for routes learned from a specied location. BGP4 usually rejects routes that
contain an AS number within an AS_PATH attribute to prevent routing loops.
capability as4 [enable | disable ] enables the capability of processing AS4s. The optional keywords enable and disable specify whether
the feature should be changed from its current state. For example, if this neighbor belongs to a peer group that is enabled for AS4s but
you want to disable it on the current interface, use the command and include the disable keyword.
capability orf prexlist [send | receive ] congures cooperative device ltering. The send and receive parameters specify the support you
are enabling:
• send - The device sends the IP prex lists as Outbound Route Filters (ORFs) to the neighbor.
• receive - The device accepts lters as Outbound Route Filters (ORFs) from the neighbor.
If you do not specify either send or receive , both capabilities are enabled. The prexlist parameter species the type of lter you want to
send to the neighbor.
NOTE
The current release supports cooperative ltering only for lters congured using IP prex
lists.
default-originate [route-mapmap-name ] congures 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 species a name for the neighbor. You can enter an alphanumeric text string up to 80 characters long.
distribute-list in | out num,num,... species a distribute list to be applied to updates to or from the specied neighbor. The in and out
keywords specify whether the list is applied on updates received from the neighbor, or sent to the neighbor. The num,num,... parameter
species the list of address-list lters. The device applies the lters in the order in which you list them and stops applying the lters in the
distribute list when a match is found.
To use an IP ACL instead of a distribute list, you can specify distribute-listACL-numin | out . In this case, ACL-num is an IP ACL.
NOTE
By default, if a route does not match any of the lters, the device denies the route. To change the default behavior, congure the
last lter as permit any any .
NOTE
The address lter must already be
congured.
ebgp-btsh enables GTSM protection for the specied neighbor.
ebgp-multihop [num ] species that the neighbor is more than one hop away and that the session type with the neighbor is EBGP-
multihop. This option is disabled by default. The num parameter species 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.
enforce-rst-as ensures, for this neighbor, that the rst AS listed in the AS_SEQUENCE eld of an AS path update message from
EBGP neighbors is the AS of the neighbor that sent the update.
lter-list in | out num,num,.. species an AS-path lter list or a list of AS-path ACLs. The in and out keywords specify 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 species the
