You can use the following commands to configure GRE tunneling (with OSPF) in this example:
Router 1 Configuration
G350-001(super)# interface FastEthernet 10/2
G350-001(super-if:FastEthernet 10/2)# ip address 11.0.0.10 255.255.255.0
G350-001(super-if:FastEthernet 10/2)# exit
G350-001(super)# interface tunnel 1
G350-001(super-if:Tunnel 1)# keepalive 10 3
Done!
G350-001(super-if:Tunnel 1)# tunnel source 11.0.0.10
Done!
G350-001(super-if:Tunnel 1)# tunnel destination 12.0.0.20
Done!
G350-001(super-if:Tunnel 1)# ip address 1.1.1.1 255.255.255.0
Done!
G350-001(super-if:Tunnel 1)# exit
G350-001(super)# ip route 12.0.0.0 255.255.255.0 11.0.0.1 1 high
G350-001(super)# router ospf
G350-001(super router:ospf)# network 1.1.1.0 0.0.0.255 area 0.0.0.0
Done!
G350-001(super router:ospf)# exit
G350-001(super)#
Router 2 Configuration
G350-001(super)# interface vlan 1
G350-001(super-if:Vlan 1)# ip address 12.0.0.10 255.255.255.0
G350-001(super-if:Vlan 1)# exit
G350-001(super)# interface tunnel 1
G350-001(super-if:Tunnel 1)# tunnel source 12.0.0.20
Done!
G350-001(super-if:Tunnel 1)# tunnel destination 11.0.0.10
Done!
G350-001(super-if:Tunnel 1)# ip address 1.1.1.2 255.255.255.0
G350-001(super-if:Tunnel 1)# exit
G350-001(super)# ip route 11.0.0.0 255.255.255.0 12.0.0.1 1 high
G350-001(super)# router ospf
G350-001(super router:ospf)# network 1.1.1.0 0.0.0.255 area 0.0.0.0
Done!
G350-001(super router:ospf)# exit
G350-001(super)#
