Multicast Forwarding Over A Gre Tunnel - HP VSR1000 Configuration Manual

Referenced route type: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows that the RPF routes to Source 2 exist on Router B and Router C. These RPF
routes are the configured static multicast routes.

Multicast forwarding over a GRE tunnel

Network requirements
As shown in
•
Multicast routing and PIM-DM are enabled on Router A and Router C. Router B does not
support multicast.
•
Router A, Router B, and Router C run OSPF. The source-side interface GigabitEthernet 1/0/1
on Router A does not run OSPF.
Configure a GRE tunnel so that the receiver host can receive the multicast data from Source.

Configuration procedure
Assign an IP address and mask for each interface, as shown in
1.
Configure OSPF on all the routers. Do not enable OSPF on GigabitEthernet 1/0/1 on Router A.

Configure a GRE tunnel:
3.
# 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.
