Monitoring Bgp Stub Routing - Cisco 7604 Configuration Manual

Configuring BGP Stub Routing
The as-number argument is the autonomous system number that identifies the FWSM to other BGP
routers and tags the routing information passed along. It must be the same as the AS number of the BGP
neighbor. After entering this command, the command prompt changes to
to indicate that you are now in router configuration mode for the specified routing process.
(Optional) Specify the router ID for the FWSM by entering the following command. If you do not enter
Step 2
a router ID, the highest IP address configured on the FWSM is used.
hostname(config-router)# bgp router-id id
The id can be any IP address, including an IP address that is not configured on the FWSM. If this
command is not specified, the router ID used is the highest IP address configured on the FWSM.
Specify the BGP neighbor that BGP updates are sent to by entering the following command:
Step 3
hostname(config-router)# neighbor ip-addr remote-as as-number
The ip-addr argument is the IP address of the BGP neighbor. The as-number is the autonomous system
number of the BGP neighbor. This should be the same as the AS number configured on the FWSM with
the router command.
(Optional) Enter the password used to authenticate the BGP message to the neighbor. This password
Step 4
must be set on both the neighbor and the FWSM before BGP messages can be exchanged.
hostname(config-router)# neighbor ip-addr password [mode] password
The ip-addr argument is the IP address of the BGP neighbor defined with the neighbor command. The
mode argument can be from 0 to 7. If used, the BGP neighbor must use the same mode. The password
argument is an alphanumeric string that can contain keyboard symbols but cannot contain spaces.
Specify the networks that the BGP routing process advertises using the network command. You can
Step 5
configure up to 200 network commands on the FWSM.
hostname(config-router)# network ip-addr mask mask
The BGP stub routing process only advertises static and directly-connected networks. The network
command defines which of those networks are advertised in BGP updates.
