MPLS Configuration On Cisco IOS Software

Multiprotocol Label Switching (MPLS) is a technique used in telecommunications networks to speed up the forwarding of network packets. In this post, we will discuss how to configure MPLS on Cisco IOS software.

To configure MPLS on a Cisco router running IOS software, follow these steps:

1. Enable MPLS on the router by entering the global configuration mode and issuing the command “mpls ip”.

2. Configure the interfaces that will be participating in MPLS by entering the interface configuration mode and issuing the command “mpls ip” on each interface.

3. Enable Label Distribution Protocol (LDP) to exchange label information between MPLS-enabled routers. Enter the global configuration mode and issue the command “mpls ldp router-id [router-id]”.

4. Enable MPLS on the interfaces that will be running LDP by entering the interface configuration mode and issuing the command “mpls ldp”.

5. Verify the MPLS configuration by entering the command “show mpls interfaces” to see the status of the MPLS interfaces.

6. To configure MPLS Virtual Private Network (VPN) on the router, enter the global configuration mode and issue the command “mpls ip vpn” to enable MPLS VPN support.

7. Configure the VPN routes by entering the VRF configuration mode and issuing the command “ip vrf [vrf-name]” to create a new VRF instance. Then, configure the routes specific to that VRF.

8. Verify the MPLS VPN configuration by entering the command “show ip route vrf [vrf-name]” to see the routes in the VRF.

By following these steps, you can successfully configure MPLS on a Cisco router running IOS software. MPLS can improve network performance and provide greater flexibility in routing traffic.
