Analysis
• If the multicast static route is not configured or updated correctly to match the current network
conditions, the route entry and the configuration information of multicast static route do not exist in
the multicast routing table.
• If a better route is found, the multicast static route may also fail.
Solution
Step1 Use the display multicast routing-table static config command to view the detailed
configuration information of multicast static routes to verify that the multicast static route has been
correctly configured and the route entry exists.
Step2 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.
Step3 8Check the type of the next hop interface of the multicast static route. If the interface is not a
point-to-point interface, be sure to specify the next hop address for the outgoing interface when you
configure the multicast static route.
Step4 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.
Step5 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
Step1 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.
Step2 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.
Step3 In the case of PIM-SM, use the display current-configuration command to check the BSR and RP
information.
