Verifying The Configuration; Troubleshooting; Ipv6 Multicast Data Fails To Reach Receivers - HP 6125XLG Configuration Manual

Verifying the configuration

The source sends the IPv6 multicast data to the multicast group FF1E::101 and the receiver host can
receive the IPv6 multicast data after joining the IPv6 multicast group. You can use the display ipv6 pim
routing-table command to display IPv6 PIM routing table information. For example:
# Display IPv6 PIM routing table information on Switch C.
[SwitchC] display ipv6 pim routing-table
Total 1 (*, G) entry; 1 (S, G) entry
(*, FF1E::101)
Protocol: pim-dm, Flag: WC
UpTime: 00:04:25
Upstream interface: NULL
Upstream neighbor: NULL
RPF prime neighbor: NULL
Downstream interface(s) information:
Total number of downstreams: 1
1: Vlan-interface200
(1001::100, FF1E::101)
Protocol: pim-dm, Flag: ACT
UpTime: 00:06:14
Upstream interface: Tunnel0
Upstream neighbor: FE80::A01:101:1
RPF prime neighbor: FE80::A01:101:1
Downstream interface(s) information:
Total number of downstreams: 1
1: Vlan-interface200
The output shows that Switch A is the RPF neighbor of Switch C and the IPv6 multicast data from Switch
A is delivered over a GRE tunnel to Switch C.

Troubleshooting

IPv6 multicast data fails to reach receivers

Symptom
IPv6 multicast data can reach some routers but fails to reach the last-hop router.
Analysis
No multicast packets can cross a multicast boundary set with the ipv6 multicast boundary command.
