GRE over IPv6 tunnel configuration example
Network requirements
Two IPv4 subnets Group 1 and Group 2 are connected to an IPv6 network. Create a GRE over IPv6
tunnel between Switch A and Switch B, so that the two IPv4 subnets can communicate with each other
through the GRE tunnel over the IPv6 network.
Figure 97 Network diagram
Configuration procedure
Before the configuration, make sure that Switch A and Switch B are reachable to each other.
Configure Switch A:
1.
<SwitchA> system-view
# Enable IPv6.
[SwitchA] ipv6
# Configure interface VLAN-interface 100.
[SwitchA] vlan 100
[SwitchA-vlan100] port Ethernet 1/0/1
[SwitchA-vlan100] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ip address 10.1.1.1 255.255.255.0
[SwitchA-Vlan-interface100] quit
# Configure interface VLAN-interface 101, the physical interface of the tunnel.
[SwitchA] vlan 101
[SwitchA-vlan101] port Ethernet 1/0/2
[SwitchA-vlan101] quit
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 address 2002::1:1 64
[SwitchA-Vlan-interface101] quit
# Create service loopback group 1, and configure the service type as tunnel.
[SwitchA] service-loopback group 1 type tunnel
