Description

Verify IPv6 over IPv4 using GRE tunnel

Topology

Step

1. Network between sw1 and port A configures as ipv6 network,network between sw1 and sw2 configures as ipv4 network, network between sw2 and port B configures as ipv6 network;
2. Configure GRE tunnel between sw1 and sw2;
3. Generate ipv6 traffic from port A to B,B to A;

tunnel mode ipv6ip

tunnel source 10.1.1.2

tunnel destination 10.1.1.1

exit

Expectation

1. In step 3, GRE tunnel can establish successfully.
2. In step 3, ipv6 traffic from port A to B, B to A can be transmitted successfully;

Result

pass
