When enabling IS-IS IPv6, you must create an IS-IS IPv6 routing process and assign it to
specific interfaces rather than to networks. You can specify only a single IS-IS process
per router.
To enable IS-IS routing, enter Global Configuration mode, and follow this procedure:
Access Global Configuration mode and specify an IPv6 license.
1.
host1(config)#license ipv6 license-value
Configure an IP address on the router to serve as the router ID.
2.
host1(config)#interface loopback0
host1(config-if)#ip address 10.6.5.4/32
Configure the lower-layer interfaces over which the IPv6 traffic flows.
3.
host1(config-if)#interface fastEthernet 1/0
Configure an IPv6 address on the interface.
4.
host1(config-if)#ipv6 address 2008::1/48
Specify the IS-IS IPv6 process to apply to the interface. Use the same tag name that
5.
you specify with the router isis command for the VR.
host1(config-if)#ipv6 router isis floor12
Repeat Steps 3–5 for all desired IPv6 interfaces.
Specify an IS-IS process globally for the VR. Use the same tag name that you specify
6.
with the ipv6 router isis command on the interface.
host1(config)#router isis floor12
Configure a Network Entity Title (NET) for the routing process that specifies the ISO
7.
network address.
host1(config-router)#net 47.0010.0000.0000.0000.0001.0001.1111.1111.1111.00
Create the IS-IS IPv6 address family for the interface.
8.
host1(config-router)#address-family ipv6 unicast
Configure any of the following desired IS-IS options for the address family:
9.
redistributing routes from other protocols, redistributing IS-IS IPv6 routes between
levels, distributing level 2 routing information to level 1 routers throughout the IS-IS
