Embodiment Construction
[0042] The embodiment of the present invention provides a method for proxying PIM at the forwarding layer where the source is directly connected to the designated router, such as Figure 4 shown, including the following steps:
[0043]Step s201, the source is directly connected to the forwarding layer of the designated router (for a centralized router, both the forwarding layer and the routing protocol layer are on the interface board; for a distributed router, the forwarding layer is the forwarding layer of the interface board, and the routing protocol layer is on the main control board board) to receive multicast data.
[0044] In step s202, the forwarding layer of the source directly connected to the designated router judges whether there is a forwarding entry for the multicast data, if yes, go to step s203, otherwise go to step s206.
[0045] In step s203, the forwarding layer of the source directly connected to the designated router checks whether there is a sending regi...
