Configuration procedure
1. Assign an IP address and mask for each interface, as shown in
2. Configure OSPF on all the routers. Do not enable OSPF on GigabitEthernet 1/0/1 on Router A.
(Details not shown.)
3. Configure a GRE tunnel:
# Create a GRE tunnel interface Tunnel 0 on Router A, and specify the tunnel mode as
GRE/IPv4.
<RouterA> system-view
[RouterA] interface tunnel 0 mode gre
# Assign an IP address to interface Tunnel 0, and specify its source and destination addresses.
[RouterA-Tunnel0] ip address 50.1.1.1 24
[RouterA-Tunnel0] source 20.1.1.1
[RouterA-Tunnel0] destination 30.1.1.2
[RouterA-Tunnel0] quit
# Create a GRE tunnel interface Tunnel 0 on Router C, and specify the tunnel mode as
GRE/IPv4.
<RouterC> system-view
[RouterC] interface tunnel 0 mode gre
# Assign an IP address to interface Tunnel 0, and specify its source and destination addresses.
[RouterC-Tunnel0] ip address 50.1.1.2 24
[RouterC-Tunnel0] source 30.1.1.2
[RouterC-Tunnel0] destination 20.1.1.1
[RouterC-Tunnel0] quit
4. Enable IP multicast routing, PIM-DM, and IGMP:
# On Router A, enable IP multicast routing.
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable PIM-DM on each interface.
[RouterA] interface gigabitethernet 1/0/1

[RouterA-GigabitEthernet1/0/1] quit
[RouterA] interface gigabitethernet 1/0/2
[RouterA-GigabitEthernet1/0/2] pim dm
[RouterA-GigabitEthernet1/0/2] quit
