Figure 43-2 GRE tunnel quotes loopback group topology
Introduction to loopback group topology
IPv6 network between SwitchA and SwitchB, PC1 and PC2 at IPv4 network, so PC1 must pass IPv6 network
between SwitchA and SwitchB to communicate with PC2 through GRE tunnel. The cards with different types
may be inserted to SwitchA, card 1 does not support GRE tunnel, card 3 supports GRE tunnel, so the data
received by card 1 needs to be processed to card 3 through loopback group function.
Configuration summary:
 Configure IPv6 network, and ensure IPv6 connectivity.
 Configure the tunnel interface, and the interface that connect PC.
 Configure the tunnel parameters and enable the tunnel interface.
 Configure loopback group, join port 1/0/12 of the card 3 in this loopback group and enable the tunnel to
quote this loopback group.
 Enable OSPF route protocol to forward the data between PC1 and PC2 through the tunnel.
Configuration steps
Instruction: the topology environment of this chapter may be different to the actual environment. To ensure the
effect of the configuration, please make sure the current configuration of the device does not conflict with the
following configuration.
