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.

#

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.

Networking Requirements

As shown in Figure 1, Ethernet 2/0/1 of the Router is connected to the uplink interface of SwitchA.

On SwitchA, the downlink interface Ethernet 2/0/1 is added to VLAN 10 and the downlink

interface Ethernet 2/0/2 is added to VLAN 20.

PC1 in VLAN 10 and PC2 in VLAN 20 need to communicate with each other

Configuration Roadmap

The configuration roadmap is as follows:

1. Add Ethernet interfaces to the VLAN.

2. Configure VLANIF interfaces.

Procedure

Step 1 Configure the Router.

# Create VLANs.

<Huawei> system-view

[Huawei] sysname Router

[Router] vlan batch 10 20

# Add interfaces to the VLANs.

[Router] interface ethernet 2/0/1

[Router-Ethernet2/0/1] port link-type trunk

[Router-Ethernet2/0/1] port trunk allow-pass vlan 10 20

[Router-Ethernet2/0/1] quit

# Assign IP addresses to the VLANIF interfaces.

[Router] interface vlanif 10

[Router-Vlanif10] ip address 10.10.10.1 24

[Router-Vlanif10] quit                   

[Router] interface vlanif 20

[Router-Vlanif20] ip address 20.20.20.1 24

[Router-Vlanif20] quit

Step 2 Configure SwitchA.

# Create VLANs.

<Huawei> system-view

[Huawei] sysname SwitchA

[SwitchA] vlan batch 10 20

# Add interfaces to the VLANs.

[SwitchA-Ethernet2/0/1] port link-type access

[SwitchA-Ethernet2/0/1] port default vlan 10

[SwitchA-Ethernet2/0/1] quit

[SwitchA] interface ethernet 2/0/2

[SwitchA-Ethernet2/0/2] port link-type access

[SwitchA-Ethernet2/0/2] port default vlan 20

[SwitchA-Ethernet2/0/2] quit

[SwitchA] interface ethernet 2/0/3

[SwitchA-Ethernet2/0/3] port link-type trunk

[SwitchA-Ethernet2/0/3] port trunk allow-pass vlan 10 20

[SwitchA-Ethernet2/0/3] quit

Step 3 Verify the configuration.

On PC1 in VLAN 10, configure the default gateway address as the IP address of VLANIF 10 (in this example: 10.10.10.1/24).

On PC2 in VLAN 20, configure the default gateway address as the IP address of VLANIF 20 (in this example: 20.20.20.1/24).

After the configuration is complete, PC1 in VLAN 10 can communicate with PC2 in VLAN 20.
