Ipv6 Multicast Data Is Abnormally Terminated On An Intermediate Router; An Rp Cannot Join An Spt In Ipv6 Pim-Sm - HP MSR2003 Configuration Manual

6. Use display current-configuration to verify that the same IPv6 PIM mode is enabled on all routers
on the network. For IPv6 PIM-SM, verify that the BSR and C-RPs are correctly configured.
7. If the problem persists, contact HP Support.
IPv6 multicast data is abnormally terminated on an
intermediate router
Symptom
An intermediate router can receive IPv6 multicast data successfully, but the data cannot reach the
last-hop router. An interface on the intermediate router receives IPv6 multicast data but does not create
an (S, G) entry in the IPv6 PIM routing table.
Analysis
If an IPv6 multicast forwarding boundary has been configured through the ipv6 multicast boundary
•
command, the IPv6 multicast packets are kept from crossing the boundary. IPv6 PIM cannot create
routing entries for the packets.
• If an ACL is defined by the source-policy command, and the IPv6 multicast packets cannot match
the ACL rules, IPv6 PIM cannot create the routing entries for the packets.
Solution
1. Use display current-configuration to verify the IPv6 multicast forwarding boundary settings. Use
ipv6 multicast boundary to change the multicast forwarding boundary settings to make the IPv6
multicast packet able to cross the boundary.
2. Use display current-configuration to verify the IPv6 multicast data filter. Change the ACL rule
defined in the source-policy command so that the source/group address of the IPv6 multicast data
can pass ACL filtering.
3. If the problem persists, contact HP Support.

An RP cannot join an SPT in IPv6 PIM-SM

Symptom
An RPT cannot be correctly built, or an RP cannot join the SPT toward the IPv6 multicast source.
Analysis
RPs are the core of an IPv6 PIM-SM domain. An RP provides services for a specific IPv6 multicast
•
group, and multiple RPs can coexist on a network. Make sure the RP information on all routers is
exactly the same to map a specific IPv6 multicast group to the same RP. Otherwise, IPv6 multicast
forwarding fails.
If a static RP is configured, use the same static RP configuration on all routers on the entire network.
•
Otherwise, IPv6 multicast forwarding fails.
Solution
1. Use display ipv6 routing-table to verify that an IPv6 unicast route to the RP is available on each
router.
2. Use display ipv6 pim rp-info to verify that the dynamic RP information is consistent on all routers.
3. Use display ipv6 pim rp-info to verify that the same static RPs are configured on all routers on the
network.
