source-address: Multicast source address.

mask: Mask of the multicast source address.

mask-length: Mask length of the multicast source address, in the range of 0 to 32.

l bgp: Specifies the BGP protocol.

l isis: Specifies the IS-IS protocol.

l ospf: Specifies the OSPF protocol.

l rip: Specifies the RIP protocol.

l statitc: Specifies a static route.

process-id: Process number of the unicast routing protocol, in the range of 1 to 65535. This argument must be provided if IS-IS, OSPF or RIP is the specified unicast routing protocol.

Description

Use the ip rpf-route-static command to configure a multicast static route.

Use the undo ip rpf-route-static command to delete a multicast static route from the multicast static routing table.

By default, no multicast static route is configured.

Note that:

l If vpn-instance is not specified, this configuration takes effect only on the public instance.

l The arguments source-address { mask | mask-length }, protocol and policy-name are critical elements in multicast static route configuration. The variation of any of these three arguments results in a different configuration.

l In the configuration, you can use the display multicast routing-table static command to check whether the multicast static route information contains this configuration. If you find a match, modify the corresponding fields without changing the configuration sequence; otherwise, add a multicast static route.

l When configuring a multicast static route, you can specify an RPF neighbor only by providing its IP address (rpf-nbr-address) rather than its interface type and number (interface-type interface-number) if the interface type of the RPF neighbor is Ethernet, Layer 3 aggregate, Loopback, RPR, or VLAN-interface.

l Because outgoing interface iteration may fail or the specified interface may be in the down state, the multicast static route configured with this command may fail to take effect. Therefore, we recommend that you use the display multicast routing-table static command after you configure a multicast static route to check whether the route has been successfully configured or whether the route has taken effect.

Related commands: display multicast routing-table static.

Default Level

2: System level

Parameters

group-address: Multicast group address, in the range of 224.0.0.0 to 239.255.255.255.

mask: Mask of the multicast group address.

mask-length: Mask length of the multicast group address, in the range of 4 to 32.

all: Specifies to remove all forwarding boundaries configured on the interface.

Description

Use the multicast boundary command to configure a multicast forwarding boundary.

Use the undo multicast boundary command to remove a multicast forwarding boundary.

By default, no multicast forwarding boundary is configured.

Note that:

l A multicast forwarding boundary sets the boundary condition for the multicast groups in the specified range. If the destination address of a multicast packet matches the set boundary condition, the packet will not be forwarded.

l If an interface needs to act as a forwarding boundary for multiple multicast groups, just carry out this command on the interface once for each group.

l Assume that Set A and Set B are both multicast forwarding boundary sets to be configured, and B is a subset of A. If A has been configured on an interface, it is not allowed to configure B on the interface; if B has been configured on the interface before A is configured, the previously configured B will be removed.
