Configuring switch C for 6in4 tunneling

Configures Switch C in a manner similar to switch B, using the appropriate IPv6 and IPv4 addresses.

Procedure
  1. Configure the Tunnel endpoint for Switch C

    The tunnel endpoint for Switch C is configured with a mode, IPv4 source address, IPv4 destination address, and an IPv6 interface address.

    Switch(config)# interface tunnel 1
    Switch(tunnel-1)# tunnel mode 6in4
    Switch(tunnel-1)# tunnel source 30.0.0.1
    Switch(tunnel-1)# tunnel destination 20.0.0.1
    Switch(tunnel-1)# ipv6 address 5000::2/64
  2. Configure VLAN 2 for the IPv6 Hosts on the 4000::/64 Network

    This step configures IPv6 address 4000::1/64 on VLAN 2. When IPv6 traffic from IPv6 host 4000::2/64 that is destined for the IPv6 3000::/64 network is transported over VLAN 2, it will be routed into the tunnel.

    This step is performed in VLAN context.

    Switch(config)# ipv6 unicast routing
    Switch(config)# ipv6 route 3000::/64 5000::1
  3. Configure IPv6 Routing to Route into the Tunnel

    IPv6 unicast routing is enabled. The static route is configured to route packets destined for the 3000::/64 network into the tunnel.

    Switch(config)# vlan 2
    Switch(vlan-2)# ipv6 address 4000::1/64

    3000::/64: Configures static route for destinations in the 3000::/64 network .

    5000::1: IPv6 address of tunnel endpoint

  4. Configure the VLAN Used to Reach the First Hop Router in the IPv4 Network

    This step configures the tunnel endpoint IPv4 address 30.0.0.1/24 (VLAN1) in VLAN 2 context so that traffic from VLAN 2 can reach the first hop router in the IPv4 network through the tunnel.

    The command is executed in VLAN context.

    Switch(vlan-2)# ip address 30.0.0.1/24
  5. Configure the IPv4 Default Gateway

    The default gateway 30.0.0.2 is configured.

    Switch(config)# ip default-gateway 30.0.0.2
