Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.

router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120.6
Enters BGP configuration mode, allowing you to configure
the BGP routing process.
Step 3
address-family {ipv4 unicast | ipv4 multicast |
| ipv6 unicast | ipv6 multicast}

RP/0/RP0/CPU0:router(config-bgp)#
address-family ipv4 unicast
Enters address family configuration mode for the specified
address family.
Step 4

table-policy tbl-plcy-A
Applies the specified policy to routes being installed into
the routing table.
Step 5
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# end
or
RP/0/RP0/CPU0:router(config-bgp-af)# 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.
