Step 3
end-policy
Example:
RP/0/RP0/CPU0:router(config-rpl)# end-policy
(Optional) Ends the definition of a route policy and exits
route policy configuration mode.
Step 4
end
or
commit
Example:
RP/0/RP0/CPU0:router(config)# end
or
RP/0/RP0/CPU0:router(config)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
Step 5
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 6
router bgp
autonomous-system-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode allowing you to configure
the BGP routing process.
Step 7
bgp router-id {
ip-address
|
interface-type
interface-instance
}
Example:
RP/0/RP0/CPU0:router(config-bgp)# bgp router-id
192.168.70.24
Configures the local router with a router id of
192.168.70.24.
Step 8
neighbor
ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor
172.168.40.24
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address
172.168.40.24 as a BGP peer.
