3. If PIM snooping is not enabled, enter VLAN view and use the pim-snooping enable command to
enable PIM snooping for the VLAN.
4. Verify that PIM snooping is operating in a PIM-SM network. PIM snooping only supports the
PIM-SM mode but not the PIM-DM mode. If the network is in the PIM-DM mode, change it to the
PIM-SM mode.
Some downstream PIM routers cannot receive multicast data
Symptom
In a network with fragmented join/prune messages, some downstream PIM routers cannot receive
multicast data.
Analysis
PIM snooping cannot reassemble messages and it cannot maintain the status of downstream routers that
the join/prune message fragments carry. To ensure the normal operation of the system, PIM snooping
must broadcast join/prune message fragments in the VLAN. However, if the VLAN has a PIM router that
has the join suppression function enabled, the broadcast join/prune message fragments might suppress
the join messages of other PIM routers in the VLAN. As a result, some PIM routers cannot receive the
multicast data destined for a specific multicast group because their join messages are suppressed. To
solve this problem, disable the join suppression function on all PIM routers that connect to the PIM
snooping device in the VLAN.
Solution
1. Use the pim hello-option neighbor-tracking command to enable the neighbor tracking function on
the interfaces of PIM routers that connect to the PIM snooping device.
2. If a PIM router cannot be enabled with the neighbor tracking function, you have to disable PIM
snooping on the device.
