IP Multicast Commands | 459The combination of the sourceipaddr and the mask fields specify the network IP address of themulticast packet source. The groupipaddr is the IP address of the next hop toward the source. Themetric is the cost of the route entry for comparison with other routes to the source network and is avalue in the range of 0 and 255. The current incoming interface is used for RPF checking formulticast packets matching this multicast static route entry.The no ip multicast staticroute sourceipaddr command deletes a static route in the static mcasttable. The sourceipaddr is the IP address of the multicast packet source.Default noneMode Global Configip multicast ttl-thresholdThis command applies the given ttlthreshold to a routing interface.Syntax ip multicast ttl-threshold ttlvalueThe ttlthreshold is the TTL threshold which is to be applied to the multicast Data packets which are tobe forwarded from the interface. The value for ttlthreshold has range from 0 to 255.The no ip multicast ttl-threshold command applies the default ttlthreshold to a routing interface.The ttlthreshold is the TTL threshold which is to be applied to the multicast Data packets which are tobe forwarded from the interface.Default 1Mode Interface Configdisable ip multicast mdebug mtraceThis command is used to disable the processing capability of mtrace query on this router. If the mode isenable, the mtrace queries received by the router are processed and forwarded appropriately by therouter. If the mode is disable, this router does not respond to the mtrace queries it receives from otherrouter devices.Syntax •noYdisable ip multicast mdebug mtraceThe no version of this command is used to enable the processing capability of mtrace query on thisrouter. If the mode is enable, the mtrace queries received by the router are processed and forwardedappropriately by the router. If the mode is disable, this router does not respond to the mtrace queries itreceives from other router devices.Default noneMode Global Config
