Configuration procedure

1. Assign an IP address and mask to each interface according to Figure 24. (Details not shown.)

2. Configure a GRE tunnel:

# Create Tunnel 0 on Router A 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

# Create Tunnel 0 on Router C 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 configure 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.
