About This Chapter
The system synchronously maintains multiple multicast routing protocols, and controls multicast
routing and forwarding through the information exchanged between the control plane and the
forwarding plane.
9.1 Overview of IPv4 Multicast Routing Management
Multicast routing and forwarding maintains a protocol routing table, multicast routing table, and
multicast forwarding table. A multicast routing protocol creates multicast routing entries through
RPF.
9.2 IPv4 Multicast Routing Management Features Supported by the S7700
The IPv4 multicast routing management features supported by the system are: static multicast
route, GRE tunnel, multicast routing policy, controlling the multicast forwarding range,
controlling the capacity of a multicast forwarding table, testing multicast routes, and multicast
splitting.
9.3 Configuring a Static Multicast Route
Static multicast routes have the functions of changing RPF routes and connecting RPF routes.
9.4 Configuring the Multicast Routing Policy
Configuring a multicast routing policy involves configuring the longest match of the multicast
route, configuring multicast load splitting, and setting a multicast load splitting weight.
9.5 Configuring the Multicast Forwarding Scope
Multicast information of each multicast group in a network should be transmitted within a certain
range. Therefore, configuring a multicast forwarding boundary are necessary for restricting the
multicast data forwarding scope.
9.6 Configuring Control Parameters of the Multicast Forwarding Table
During network planning, you can restrict the capacity of the forwarding table on a multicast
device, such as the maximum number of entries in the multicast forwarding table and the
maximum number of downstream interfaces of multicast forwarding entries. In this manner,
traffic load on the multicast device is released and the fault risk resulted from excessive entries
can be avoided.
