ONFIGURATION
[RouterB-Tunnel0] ip address 10.1.2.2 255.255.255.0
# Configure the tunnel encapsulation mode.
[RouterB-Tunnel0] tunnel-protocol gre
# Configure the source address of interface Tunnel0 to be the IP address of
interface Serial 2/1.
[RouterB-Tunnel0] source 2.2.2.2
# Configure the destination address of interface tunnel 0 to be the IP address of
interface Serial 2/0 on Router A.
[RouterB-Tunnel0] destination 1.1.1.1
[RouterB-Tunnel0] quit
# Configure a static route from Router B through interface Tunnel0 to Group 1.
[RouterB] ip route-static 10.1.1.0 255.255.255.0 tunnel 0
Network requirements
Two IPv4 subnets Group 1 and Group 2 are interconnected through a GRE tunnel
over the IPv6 network between Router A and Router B.
