Purpose

Step 18

 

 

route-policyroute-policy-name out

Applies the pass-all policy to all outbound routes.

 

Example:

 

 

RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#

 

 

route-policy pass-all out

 

Step 19

 

 

end

Saves configuration changes.

 

or

When you issue the end command, the system prompts

 

 

 

commit

you to commit changes:

 

 

Uncommitted changes found, commit them before

 

Example:

exiting(yes/no/cancel)?

 

RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#

[cancel]:

 

 

 

end

Entering yes saves configuration changes to the

 

or

 

RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#

running configuration file, exits the configuration

 

session, and returns the router to EXEC mode.

 

commit

 

 

 

 

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.

 

 

 

Verifying MPLS VPN over IP

To verify the configuration of end-end (PE-PE) MPLS VPN over IP provisioning, use the following show commands:

show cef recursive-nexthop

show bgp ipv4 tunnel

show bgp vpnv4 unicast summary

show bgp vrf v1 ipv4 unicast summary

show bgp vrf v1 ipv4 unicast prefix

show cef vrf v1 ipv4 prefix

show cef ipv6 recursive-nexthop

show bgp vpnv6 unicast summary

show bgp vrf v1 ipv6 unicast summary

show bgp vrf v1 ipv6 unicast prefix

show cef vrf v1 ipv6 prefix
