SUMMARY STEPS
1. configure
2. router bgp autonomous-system-number
3. neighbor ip-address
4. remote-as autonomous-system-number
5. address-family {ipv4 unicast | ipv4 multicast | ipv6 unicast | ipv6 multicast}
6. end
or
commit
Step 19
use neighbor-group
group-name
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# use
neighbor-group nbr-grp-A

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.
