Configuration procedure
1. Configure the IP address and mask for each interface as per
2. Configure a GRE tunnel:
# On Router A, create interface Tunnel 0 and configure the IP address and mask for the interface.
<RouterA> system-view
[RouterA] interface tunnel 0
[RouterA-Tunnel0] ip address 50.1.1.1 24
# On Router A, specify the tunnel encapsulation mode as GRE over IPv4 and specify the source
and destination addresses of the interface.
[RouterA-Tunnel0] tunnel-protocol gre
[RouterA-Tunnel0] source 20.1.1.1
[RouterA-Tunnel0] destination 30.1.1.2
[RouterA-Tunnel0] quit
# On Router C, create interface Tunnel 0 and configure the IP address and mask for the interface.
<RouterC> system-view
[RouterC] interface tunnel 0
[RouterC-Tunnel0] ip address 50.1.1.2 24
# On Router C, specify the tunnel encapsulation mode as GRE over IPv4 and specify the source
and destination addresses of the interface.
[RouterC-Tunnel0] tunnel-protocol gre
[RouterC-Tunnel0] source 30.1.1.2
[RouterC-Tunnel0] destination 20.1.1.1
[RouterC-Tunnel0] quit
3. Configure OSPF:
# Configure OSPF on Router A.
[RouterA] ospf 1
[RouterA-ospf-1] area 0
[RouterA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[RouterA-ospf-1-area-0.0.0.0] network 20.1.1.0 0.0.0.255
[RouterA-ospf-1-area-0.0.0.0] network 50.1.1.0 0.0.0.255
[RouterA-ospf-1-area-0.0.0.0] quit
[RouterA-ospf-1] quit
# Configure OSPF on Router B.
