Configure OSPF Transport and Service Integrations

Updated: June 26, 2026

Want to summarize with AI?

Provides configure procdures for enabling OSPF Version 2 on Cisco 8000 Series Routers, integrating advanced features such as MPLS Traffic Engineering, LDP auto-configuration, and VRF-based OSPF instances using a repeatable workflow. This process enables scalable, service-ready routing in complex networks.

Set up OSPF Version 2 with advanced integrations for MPLS Traffic Engineering, LDP auto-configuration, and VRF-based OSPF instances on Cisco 8000 Series Routers.

Use this task when deploying or expanding Cisco 8000 Series Routers to support enhanced OSPF capabilities. These integrations ensure optimal scalability and readiness for managed services and MPLS environments.

Before you begin

Ensure that MPLS and IP Cisco Express Forwarding (CEF) are enabled on your router.
Verify that your network supports MPLS Traffic Engineering for OSPF operations.

Follow these steps to configure and verify OSPF transport and service integrations:

Procedure

Configure OSPF Version 2 for MPLS Traffic Engineering.

Example:


Router# configure
Router(config)# router ospf 1
Router(config-ospf)# router-id 192.168.4.3
Router(config-ospf)# mpls traffic-eng router-id loopback 0
Router(config-ospf)# area 0
Router(config-ospf)# mpls traffic-eng
Router(config-ospf-ar)# interface loopback0

Enable Label Distribution Protocol (LDP) IGP auto-configuration for OSPF.

Example:


Router# configure
Router(config)# router ospf 1
Router(config-ospf)# mpls ldp auto-config

Associate an interface with a VPN Routing and Forwarding (VRF) instance in OSPF.

Example:


Router# configure
Router(config)# router ospf 1
Router(config-ospf)# vrf vrf1
Router(config-ospf-vrf)# area 0
Router(config-ospf-vrf-ar)# interface GigabitEthernet0/0/0/0

Your Cisco 8000 Series Router is now running OSPF Version 2, integrated with MPLS Traffic Engineering, LDP auto-configuration, and VRF-aware OSPF. The router is ready for scalable, service-rich routing as per your network requirements.

What to do next

Verify OSPF and MPLS configurations using show ospf, show mpls ldp neighbors, and confirm integration.
Adjust OSPF areas, VRFs, or interfaces as required for your deployment.
