Testing the MPLS Network Configuration
Preliminary testing of the MPLS network consists of:
• Checking VSI status
• Checking the MPLS interfaces
• Checking the MPLS discovery process
The following Cisco IOS commands are useful for monitoring and troubleshooting an MPLS network:
• show controllers VSI descriptor [descriptor]
• show mpls interfaces
• show mpls ldp discovery
Note Cisco IOS commands must be entered at the Cisco IOS CLI in order to function. If you are logged in to
the switch, start a separate terminal session to log into either the LSC router portion of the ATM-LSR
or the network’s edge routers.
