IPv6 router configuration

Overview

• Basic connectivity configuration for IPv6

• Configuration for IPv6 tunnel

• Configuration of static route

• Configuration of OSPF

• Configuration of BGP

Basic connectivity configuration

• How to implement

– Configure IPv6 and enable IPv6 routing

– Configure the prefixes

• Manually

• Based on a 6to4 interface

• Dynamic prefix delegation

• Interface dual stacks support

Basic connectivity configuration

• Manually

– Defines the prefixes for an IPv6 address

• Need to specify both IPv6 prefix and prefix

length

ipv6 general-prefix prefix-name { ipv6-prefix/prefix-

length | 6to4 interface-type interface-number }

Example:

Router(config)# ipv6 general-prefix my-prefix

2001:0DB8:2222::/48

Basic connectivity configuration

• Based on a 6to4 interface

– Specify the 6to4 keyword and the interface

type / interface number

• When defining the 6to4 prefix

2001:a.b.c.d::/48 (a.b.c.d is the IPv4

address of the interface referenced

ipv6 general-prefix prefix-name { ipv6-prefix/prefix-length

| 6to4 interface-type interface-number }

Example:

Router(config)# ipv6 general-prefix my-prefix 6to4
