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
Step 18
route-policy route-policy-name out
Example:
RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#
route-policy pass-all out
Applies the pass-all policy to all outbound routes.
Step 19
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-af)#
end
or
RP/0/RP0/CPU0:router(config-bgp-vrf-nbr-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.
