Explains how virtual and sham links maintain OSPF connectivity and optimize MPLS VPN routing, and describes integrations with LDP, MPLS Traffic Engineering, VRFs, route redistribution, management interfaces, and security mechanisms.
OSPF virtual links and sham links
Describes OSPF virtual links and sham links for Cisco 8000 Series Routers running IOS XR. Use this topic to understand the OSPF behavior, dependencies, and design considerations before you configure or verify the feature.
OSPF integrations and management support
Explains OSPF integrations and management support options for Cisco 8000 Series Routers running IOS XR.
Configure LDP IGP synchronization for OSPF
Configure Label Distribution Protocol (LDP) Interior Gateway Protocol (IGP) synchronization for OSPF to prevent traffic loss and improve network stability during network changes.
Configure OSPF Transport and Service Integrations
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.
Configure OSPF virtual and sham links
Provides configuration procedures for enabling OSPF virtual and sham links to maintain backbone connectivity and optimize routing on Cisco 8000 Series Routers.
