Example for Configuring IPv6 Static Routes

Networking requirements

Figure 1 shows an IPv6 network. PC1, PC2, and PC3 are on different network segments, and are connected through SwitchA, SwitchB, and SwitchC. Any two PCs must be connected using static routes to communicate with each other without using dynamic routing protocols.

Figure 1 Configuring IPv6 static routes

Configuration Roadmap

The configuration roadmap is as follows:

Create VLANs, add interfaces to the VLANs, and assign IPv6 addresses to VLANIF interfaces so that neighboring devices can communicate with each other.
Configure an IPv6 default gateway on each PC, and configure IPv6 static routes or default static routes on each Switch so that any two PCs on different network segments can communicate with each other.

Procedure

Add interfaces to VLANs.

# Configure SwitchA. The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA.

<HUAWEI> system-view
[HUAWEI] sysname SwitchA
[SwitchA] vlan batch 10 20
[SwitchA] interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] port link-type trunk
[SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 20
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2] port link-type access
[SwitchA-GigabitEthernet0/0/2] port default vlan 10
[SwitchA-GigabitEthernet0/0/2] quit

Assign IPv6 addresses to VLANIF interfaces.

# Configure SwitchA. The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA.

[SwitchA] ipv6
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ipv6 enable
[SwitchA-Vlanif10] ipv6 address fc00:0:0:2001::1/64
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ipv6 enable
[SwitchA-Vlanif20] ipv6 address fc00:0:0:2010::1/64
[SwitchA-Vlanif20] quit

Configure IPv6 addresses for the PCs and default gateway addresses.
Assign IPv6 addresses to the PCs, and set the default gateway address of PC1, PC2, and PC3 to fc00:0:0:2001::1, fc00:0:0:2002::1, and fc00:0:0:2003::1 respectively.

Configure IPv6 static routes.

# Configure a default IPv6 static route on SwitchA.

[SwitchA] ipv6 route-static :: 0 vlanif20 fc00:0:0:2010::2

# Configure two IPv6 static routes on SwitchB.

[SwitchB] ipv6 route-static fc00:0:0:2001:: 64 vlanif20 fc00:0:0:2010::1

[SwitchB] ipv6 route-static fc00:0:0:2003:: 64 vlanif40 fc00:0:0:2020::2

# Configure a default IPv6 static route on SwitchC.

[SwitchC] ipv6 route-static :: 0 vlanif40 fc00:0:0:2020::1

Verify the configuration.

# Check the IPv6 routing table on SwitchA.
