How to Configure IS-IS IPv6 for Huawei Routers

Applicability

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

Networking Requirements

As shown in Figure 1:

• 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.
