Rps Unable To Join Spt In Ipv6 Pim-Sm; Rpt Establishment Failure Or Source Registration Failure In Ipv6 Pim-Sm - HP A6600 Configuration Manual

Check that the RPF neighbor is an IPv6 PIM neighbor. Use display pim ipv6 neighbor to view the PIM
3.
neighbor information.
Check that IPv6 PIM and MLD are enabled on the interfaces directly connecting to the IPv6 multicast
4.
source and to the receiver.
Check that the same IPv6 PIM mode is enabled on related interfaces. Use display pim ipv6 interface
5.
verbose to check whether the same PIM mode is enabled on the RPF interface and the
corresponding interface of the RPF neighbor router.
Check that the same IPv6 PIM mode is enabled on all the routers in the entire network. Use display
6.
current-configuration to check the IPv6 PIM mode information on each interface. Make sure that the
same IPv6 PIM mode is enabled on all the routers: IPv6 PIM-SM on all routers, or IPv6 PIM-DM on all
routers.

RPs unable to join SPT in IPv6 PIM-SM

Symptom
An RPT cannot be established correctly, or the RPs cannot join the SPT to the IPv6 multicast source.
Analysis
As the core of an IPv6 PIM-SM domain, the RPs serves specific IPv6 multicast groups. Multiple RPs
•
can coexist in a network. Make sure that the RP information on all routers is exactly the same, and a
specific group is mapped to the same RP. Otherwise, IPv6 multicast will fail.
In the case of the static RP mechanism, the same RP address must be configured on all the routers in
•
the entire network, including static RPs, by means of the static RP command. Otherwise, IPv6
multicast will fail.
Solution
Check that a route is available to the RP. Carry out the display ipv6 routing-table command to check
1.
whether a route is available on each router to the RP.
Check the dynamic RP information. Use the display pim ipv6 rp-info command to check whether the
2.
RP information is consistent on all routers. In the case of inconsistent RP information, configure
consistent RP address on all the routers.
Check the static RP configuration. Carry out the display pim ipv6 rp-info command to check whether
3.
the same RP address has been configured on all the routers throughout the network.
RPT establishment failure or source registration failure in IPv6
PIM-SM
Symptom
C-RPs cannot unicast advertise messages to the BSR. The BSR does not advertise bootstrap messages
containing C-RP information and has no unicast route to any C-RP. An RPT cannot be established correctly,
or the DR cannot perform source register with the RP.
Analysis
• C-RPs periodically send advertisement messages to the BSR by unicast. If a C-RP does not have a
route to the BSR, the BSR cannot receive the advertisements from the C-RP, and therefore the
bootstrap messages of the BSR will not contain the information about that C-RP.
