Configuration Examples for Implementing IS-IS
This section provides the following configuration examples:

Configuring Single-Topology IS-IS for IPv6: Example

The following example shows single-topology mode being enabled. An IS-IS instance is created, the NET is
defined, IPv6 is configured along with IPv4 on an interface, and IPv4 link topology is used for IPv6.
This configuration allows POS interface 0/3/0/0 to form adjacencies for both IPv4 and IPv6 addresses.

net 49.0000.0000.0001.00

interface POS0/3/0/0
!
interface POS0/3/0/0
ipv4 address 10.0.1.3 255.255.255.0
ipv6 address 2001::1/64

Configuring Multitopology IS-IS for IPv6: Example

The following example shows multitopology IS-IS being configured in IPv6.
router isis isp
net 49.0000.0000.0001.00
interface POS0/3/0/0
!
interface POS0/3/0/0
ipv6 address 2001::1/64

Purpose
(Optional) If link-group is configured on the interface, when
showing the IS-IS interface-related topology, this command
displays the link-group value.
