Example for Configuring IS-IS IPv6

Example for Configuring IS-IS IPv6

Applicability

This example applies to all AR models of V200R002C00 and later versions.

Networking Requirements

As shown in Figure 8-24:

  • RouterA, RouterB, RouterC, and RouterD belong to the same AS. The four routers need to run IS-IS to implement IPv6 interworking.

  • RouterA, RouterB, and RouterC belong to Area 10, and RouterD belongs to Area 20.

  • RouterA and RouterB are Level-1 routers, RouterC is a Level-1-2 router, and RouterD is a Level-2 router.

Procedure

  1. Configure RouterA.

    #
 sysname RouterA
#
 ipv6  //Enable IPv6 unicast forwarding.
#
isis 1  //Enable IS-IS process 1.
 is-level level-1  //Set the router as a Level-1 router.
 network-entity 10.0000.0000.0001.00  //Set the NET for IS-IS process 1.
 #
 ipv6 enable topology standard  //Enable the IPv6 capability for IS-IS process 1.
 #
#
interface GigabitEthernet1/0/0
 ipv6 enable  //Enable IPv6 on the interface.
 ipv6 address 10:1::2/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1  //Enable the IPv6 capability for IS-IS process 1 on the interface.
#
return

  2. Configure RouterB.

    #
 sysname RouterB
#
 ipv6
#
isis 1
 is-level level-1
 network-entity 10.0000.0000.0002.00  //Set the NET for IS-IS process 1.
 #
 ipv6 enable topology standard
 #
#
interface GigabitEthernet1/0/0
 ipv6 enable
 ipv6 address 10:2::2/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
#
return

  3. Configure RouterC.

    #
 sysname RouterC
#
 ipv6
#
isis 1
 network-entity 10.0000.0000.0003.00  //Set the NET for IS-IS process 1.
 #
 ipv6 enable topology standard
 #
#
interface GigabitEthernet0/0/0
 ipv6 enable
 ipv6 address 30::1/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
 isis circuit-level level-2  //Set the circuit type as Level-2, allowing only Level-2 adjacencies to be established on the interface.
#
interface GigabitEthernet1/0/0
 ipv6 enable
 ipv6 address 10:1::1/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
#
interface GigabitEthernet2/0/0
 ipv6 enable
 ipv6 address 10:2::1/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
#
return

  4. Configure RouterD.

    #
 sysname RouterD
#
 ipv6
#
isis 1
 is-level level-2  //Set the router as a Level-2 router.
 network-entity 20.0000.0000.0004.00  //Set the NET for IS-IS process 1.
 #
 ipv6 enable topology standard
 #
#
interface GigabitEthernet1/0/0
 ipv6 enable
 ipv6 address 30::2/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
#
interface GigabitEthernet2/0/0
 ipv6 enable
 ipv6 address 20::1/64  //Configure a global unicast IPv6 address for the interface.
 isis ipv6 enable 1
#
return

  5. Verify the configuration.

    # Run the display isis route command on each router to view IS-IS routes.

    # Interfaces on RouterA, RouterB, RouterC, and RouterD can successfully ping each other.

Configuration Notes

  • IPv6 must be enabled in the system view and interface view.
  • The IPv6 capability must be enabled for IS-IS on interfaces.
  • When using the network-entity command to set a NET for an IS-IS process, configure the same area ID for routers in an area.
