3. Configure a GRE tunnel:
# Create interface Tunnel 0 on Router A and specify the tunnel encapsulation mode as GRE over
IPv6.
<RouterA> system-view
[RouterA] interface tunnel 0 mode gre ipv6
# Configure the IPv6 address for interface Tunnel 0 on Router A and specify its source and
destination addresses.
[RouterA-Tunnel0] ipv6 address 5001::1 64
[RouterA-Tunnel0] source 2001::1
[RouterA-Tunnel0] destination 3001::2
[RouterA-Tunnel0] quit
# Create interface Tunnel 0 on Router C and specify the tunnel encapsulation mode as GRE over
IPv6.
<RouterC> system-view
[RouterC] interface tunnel 0 mode gre ipv6
# Configure the IPv6 address for interface Tunnel 0 and specify its source and destination
addresses.
[RouterC-Tunnel0] ipv6 address 5001::2 64
[RouterC-Tunnel0] source 3001::2
[RouterC-Tunnel0] destination 2001::1
[RouterC-Tunnel0] quit
4. Enable IPv6 multicast routing, IPv6 PIM-DM, and MLD:
# On Router A, enable IPv6 multicast routing, and enable IPv6 PIM-DM on each interface.
[RouterA] ipv6 multicast routing
[RouterA-mrib6] quit
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] ipv6 pim dm
[RouterA-Ethernet1/1] quit
[RouterA] interface ethernet 1/2
[RouterA-Ethernet1/2] ipv6 pim dm
[RouterA-Ethernet1/2] quit
[RouterA] interface tunnel 0
[RouterA-Tunnel0] ipv6 pim dm
[RouterA-Tunnel0] quit
# On Router C, enable IPv6 multicast routing, enable MLD on Ethernet 1/1, and enable IPv6
PIM-DM on each interface.
[RouterC] ipv6 multicast routing
[RouterC-mrib6] quit
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] mld enable
[RouterC-Ethernet1/1] ipv6 pim dm
[RouterC-Ethernet1/1] quit
[RouterC] interface ethernet 1/2
[RouterC-Ethernet1/2] ipv6 pim dm
[RouterC-Ethernet1/2] quit
[RouterC] interface tunnel 0
