Ipv6 Multicast Forwarding Over A Gre Tunnel Configuration Example - HP FlexNetwork 7500 Series Configuration Manual

IPv6 multicast forwarding over a GRE tunnel
configuration example
Network requirements
As shown in
•
IPv6 multicast routing and IPv6 PIM-DM are enabled on Switch A and Switch C.
•
Switch B does not support IPv6 multicast.
•
Switch A, Switch B, and Switch C run OSPFv3. The source-side interface (VLAN-interface 100)
on Switch A does not run OSPFv3.
Configure the switches so that the receiver host can receive the IPv6 multicast data from the source.

Configuration procedure
Assign an IPv6 address and prefix length to each interface, as shown in
1.
shown.)
Configure OSPFv3 on the switches. Do not run OSPFv3 on VLAN-interface 100 on Switch A.

Configure a GRE tunnel:
3.
# On Switch A, create service loopback group 1, and specify the unicast tunnel service for the
group.
<SwitchA> system-view
[SwitchA] service-loopback group 1 type tunnel
# Assign GigabitEthernet 1/0/3 to service loopback group 1. (GigabitEthernet 1/0/3 does not
belong to VLAN 100 or VLAN 101.)
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] port service-loopback group 1
[SwitchA-GigabitEthernet1/0/3] quit
# Create a GRE tunnel interface Tunnel 1, and specify the tunnel mode as GRE/IPv6.
[SwitchA] interface tunnel 1 mode gre ipv6
# Assign an IPv6 address to interface Tunnel 1, and specify its source and destination
addresses.
