Provides key facts about OSPF implementation, supported features, and protocol details for Cisco 8000 Series Routers running IOS XR.
The OSPF protocol is an Interior Gateway Protocol (IGP) developed by the OSPF working group of the Internet Engineering Task Force (IETF) for IP networks. OSPF supports IP subnetting, tagging of externally derived routing information, and packet authentication.
Cisco 8000 Series Routers running IOS XR support both OSPF Version 2 (OSPFv2) for IPv4 and OSPF Version 3 (OSPFv3) for IPv6. OSPFv3 adds support for IPv6 routing prefixes.
-
IP subnetting and tagging of external routing information
-
Packet authentication for secure communication
-
Operational integration and resiliency features designed for complex network environments
-
Support for both OSPFv2 (IPv4) and OSPFv3 (IPv6)
Understanding OSPF behavior, dependencies, and design considerations is recommended before configuring or verifying OSPF features.
