BigIron RX Series Configuration Guide 64753-1001986-01Configuring a static multicast route 23Displaying information about an upstream neighbordeviceYou can view information about the upstream neighbor device for a given source IP address for IPPIM packets. The software uses the IP route table or multicast route table to lookup the upstreamneighbor device.The following shows example messages that the Brocade device can display with this command.BigIron RX# show ip dvmrp rpf 1.1.20.2|directly connected or via an L2 neighborBigIron RX# show ip dvmrp rpf 1.2.3.4no routeBigIron RX# show ip dvmrp rpf 1.10.10.24upstream neighbor=1.1.20.1 on v21 using ip routeSyntax: show ip dvmrp rpf Where is a valid source IP addressNOTEIf there are multiple equal cost paths to the source, the show ip dvmrp rpf command output may notbe accurate. If your system has multiple equal cost paths, use the command show ip dvmrp mcacheto view information about the upstream neighbor.Configuring a static multicast routeThe ip mroute command is used to direct multicast traffic along a specific path. The ip mroutecommand starts with the ip address or ingress ip address the source traffic is received upon. Theingress interface network mask, and the next hop address leading back to the ingress source ipaddress.To configure static IP multicast routes, enter a command such as the following.BigIron RX(config)# ip mroute 12.7.1.0 255.255.255.0 17.3.1.2If you configure more than one static multicast route, the BigIron RX Series router always uses themost specific route that matches a multicast source address. Thus, if you want to configure amulticast static route for a specific multicast source and also configure another multicast staticroute for all other sources, you can configure two static routes.Syntax: [no] ip mroute [ | ethernet | ve | null0] [] [distance < num>]The ip-addr and ip-mask parameters specifies the PIM source for the route.The ethernet parameter specifies a physical port.The ve parameter specifies a virtual interface.The null0 parameter is the same as dropping the traffic.The distance parameter sets the administrative distance for the route.The parameter specifies the cost metric of the route. Possible values are: 1 - 6 Defaultvalue: 1
