How to Configure IPv6 Support on the Cisco ASR 901 Router

Configuring BFDv6 and OSPFv3

This section describes the procedures for configuring BFD support for OSPFv3, so that OSPFv3 is a registered protocol with BFD and will receive forwarding path detection failure messages from BFD.

There are two methods for enabling BFD support for OSPFv3:

•You can enable BFD for all of the interfaces for which OSPFv3 is routing by using the bfd all-interfacescommand in router configuration mode.

•You can enable BFD for a subset of the interfaces for which OSPFv3 is routing by using the ipv6 ospf bfd command in interface configuration mode.

Prerequisites

•OSPFv3 must be running on all participating routers.

•The baseline parameters for BFD sessions on the interfaces over which you want to run BFD sessions to BFD neighbors must be configured.

SUMMARY STEPS

1.enable

2.configure terminal

3.ipv6 router ospf process-id

4.bfd all-interfaces

5.exit

DETAILED STEPS

	Command or Action	Purpose
Step 1
	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	ipv6 router ospf process-id	Configures an OSPFv3 routing process.
		• process-id—Internal identification. It is locally
	Example:	assigned and can be a positive integer from 1 to 65535.
	Router(config)# ipv6 router ospf 2	The number used here is the number assigned
		administratively when enabling the OSPF for IPv6
		routing process.
