Setting BGP Administrative Distance
Perform this task to specify the use of administrative distances that can be used to prefer one class of
route over another.
SUMMARY STEPS
1. configure
2. router bgp autonomous-system-number
3. address-family {ipv4 unicast | ipv4 multicast | ipv6 unicast | ipv6 multicast}
4. distance bgp external-distance internal-distance local-distance
5. end
or
commit
Step 4
table-policy
policy-name
Example:
RP/0/RP0/CPU0:router(config-bgp-af)#
table-policy tbl-plcy-A
Applies the tbl-plcy-A policy to IPv4 unicast routes being
installed into the routing table.

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.
