Multicast forwarding over a GRE tunnel
Network requirements
Multicast routing and PIM-DM are enabled on Switch A and Switch C. Switch B does not support
multicast. OSPF is running on Switch A, Switch B, and Switch C.
Perform the configuration so that the receiver host can receive the multicast data from the source.

Configuration procedure
1. Configure the IP address and subnet mask for each interface as shown in Figure 20. (Details not
shown.)
2. Enable OSPF on switches to make sure the network-layer among the switches is interoperable and
the routing information among the switches can be dynamically updated. (Details not shown.)
3. Configure a GRE tunnel:
# Create service loopback group 1 on Switch A and specify its service type as Tunnel.
<SwitchA> system-view
[SwitchA] service-loopback group 1 type tunnel
# Disable STP and LLDP on interface Ten-GigabitEthernet 1/0/3 of Switch A, and add the
interface to service loopback group 1. Ten-GigabitEthernet 1/0/3 does not belong to VLAN 100
or VLAN 101.
[SwitchA] interface ten-gigabitethernet 1/0/3
[SwitchA-Ten-GigabitEthernet1/0/3] undo stp enable
[SwitchA-Ten-GigabitEthernet1/0/3] undo lldp enable
[SwitchA-Ten-GigabitEthernet1/0/3] port service-loopback group 1
[SwitchA-Ten-GigabitEthernet1/0/3] quit
# Create interface Tunnel 0 on Switch A and specify the tunnel encapsulation mode as GRE over
IPv4.
[SwitchA] interface tunnel 0 mode gre
# Configure the IP address for interface Tunnel 0 on Switch A and specify its source and
destination addresses.
