Configuration procedure

1. Configure Router A:

# Specify the IPv6 address of interface Ethernet 1/1.

<RouterA> system-view

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] ipv6 address 2002::1 64

[RouterA-Ethernet1/1] quit

# Configure a static route.

[RouterA] ipv6 route-static 2001:: 64 2002::2

2. Configure Router C:

# Specify the IPv6 address of interface Ethernet 1/2.

<RouterC> system-view

[RouterC] interface ethernet 1/2

[RouterC-Ethernet1/2] ipv6 address 2001::1 64

[RouterC-Ethernet1/2] quit

# Configure a static route.

[RouterC] ipv6 route-static 2002:: 64 2001::2

3. Configure Router B:

# Enable IPv6 fast forwarding.

<RouterB> system-view

[RouterB] ipv6 fast-forwarding

# Specify the IPv6 addresses of interface Ethernet 1/1 and interface Ethernet 1/2.

[RouterB] interface ethernet 1/1

[RouterB-Ethernet1/1] ipv6 address 2002::2 64

[RouterB-Ethernet1/1] quit

[RouterB] interface ethernet 1/2

[RouterB-Ethernet1/2] ipv6 address 2001::2 64

[RouterB-Ethernet1/2] quit

Verifying the configuration

# Display the IPv6 fast forwarding table on Router B.
