Configuration Examples; Ipv6 Multicast Forwarding Over A Gre Tunnel - HP MSR1002-4 Configuration Manual

Task
Clear IPv6 multicast routing entries.
NOTE:
•
When you clear an IPv6 multicast routing entry, the associated IPv6 multicast forwarding entry is also
cleared.
•
When you clear an IPv6 multicast forwarding entry, the associated IPv6 multicast routing entry is also
cleared.

Configuration examples

IPv6 multicast forwarding over a GRE tunnel

Network requirements
As shown in
•
IPv6 multicast routing and IPv6 PIM-DM are enabled on Router A and Router C.
•
Router B does not support IPv6 multicast.
•
Router A, Router B, and Router C run OSPFv3. The source-side interface GigabitEthernet 1/0/1
on Router A does not run OSPFv3.
Configure a GRE tunnel so that the receiver host can receive the IPv6 multicast data from Source.

Configuration procedure
1. Assign an IPv6 address and prefix length to each interface, as shown in
shown.)
2. Configure OSPFv3 on the routers. Do not run OSPFv3 on the source-side interface
GigabitEthernet 1/0/1 on Router A. (Details not shown.)
3. Configure a GRE tunnel:
# Create an IPv6 GRE tunnel interface Tunnel 0 on Router A.
