ip as-path-access-list 1 permit _200$
ip as-path-access-list 1 permit ^100$

The commands below enable BGP and specify an autonomous system, define two
neighbor peers, assign the AS path list to one of the neighbor BGP peers, and assign a
second AS path list to the other neighbor to indicate that outbound routes have the
conditions defined in AS-path access-list 2 applied.
router bgp 100
neighbor 156.30.10.22 remote-as 200
neighbor 160.25.15.10 remote-as 300
neighbor 156.30.10.22 filter-list 1 out
neighbor 156.30.10.22 filter-list 2 out
Configuring an IP Access Group
No access groups defined by default on the BSR. Use the
ip access-group
command
in Interface Configuration mode to configure an interface to use an access list.
MOT(config-if)#
ip access-group
{<
1-199
> <
1300-2699
> {
in
|
out
}
where:
1-199
is the standard access list
1300-2699
is the extended access list
in
incoming packet is processed only if the source-address is in the access-list.
out
permits the outgoing packet to be processed only if access-list permits the
packet.
Creating Community Lists
You can use the community to control the routing information a BGP speaker accepts,
prefers, or distributes to other neighbors. The BGP community attribute passes
between peers when they exchange information about how they connect to each other.
You can use the following predefined community attribute keywords with the
set
community
command in a route map:
Note:
Use the
no ip access-group
command to delete an access group on
an interface.
