GRE over IPv6 tunnel configuration example
Network requirements
As shown in Figure 102, two IPv4 subnets Group 1 and Group 2 are connected to an IPv6 network.
Create a GRE over IPv6 tunnel between Router A and Router B, so that the two IPv4 subnets can
communicate with each other through the GRE tunnel over the IPv6 network.
Figure 102 Network diagram
Configuration procedure
Before the configuration, make sure Router A and Router B can reach each other.
1. Configure Router A:
<RouterA> system-view
# Enable IPv6.
