2) In the configuration, you can use the display multicast routing-table static command to
view the information of multicast static routes to verify that the multicast static route has
been correctly configured and the route entry exists in the multicast routing table.
3) Check the next hop interface type of the multicast static route. If the interface is not a
point-to-point interface, be sure to specify the next hop address to configure the outgoing
interface when you configure the multicast static route.
4) Check that the multicast static route matches the specified routing protocol. If a protocol
was specified in multicast static route configuration, enter the display ip routing-table
command to check if an identical route was added by the protocol.
5) Check that the multicast static route matches the specified routing policy. If a routing policy
was specified when the multicast static route was configured, enter the display
route-policy command to check the configured routing policy.
Multicast Data Fails to Reach Receivers
Symptom
The multicast data can reach some routers but fails to reach the last hop router.
Analysis
If a multicast forwarding boundary has been configured through the multicast boundary
command, any multicast packet will be kept from crossing the boundary.
Solution
1) Use
the
display pim routing-table command to check whether the corresponding (S, G)
entries exist on the router. If so, the router has received the multicast data; otherwise, the
router has not received the data.
2) Use
the
display multicast boundary command to view the multicast boundary information
on the interfaces. Use the multicast boundary command to change the multicast
forwarding boundary setting.
3) In the case of PIM-SM, use the display current-configuration command to check the BSR
and RP information.
