Configuring An Ip Access Group; Creating Community Lists - Motorola BSR 2000 Configuration And Management Manual

BSR 2000 Configuration and Management Guide
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.

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.
Note: Use the no ip access-group command to delete an access group on
an interface.
MOT(config-if)# ip access-group {<1-199> <1300-2699> {in | out}

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:
8-8
ip as-path-access-list 1 permit _200$
ip as-path-access-list 1 permit ^100$
ip as-path-access-list 2 deny _690$
ip as-path-access-list 2 permit .*
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
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.
