The invention discloses a method for implementing two-way
protocol independent multicast (PIM) and equipment. According to the method, an equivalent routing number for allowed
load sharing is configured on each piece of routing equipment in a two-way PIM network; each piece of routing equipment generates corresponding quantity of designated
forwarder (DF) election examples according to the equivalent routing number for allowed
load sharing and elects a DF interface corresponding to each DF election example, wherein a
reverse path forwarding (RPF) interface corresponding to each DF election example is selected from an equivalent routing interface set of the routing equipment by the routing equipment in a
polling way; and when generating a
multicast forwarding table entry, the routing equipment is matched to the corresponding DF election example according to a corresponding
multicast group, acquires the RPF interface which corresponds to the matched DF election example, and generates a corresponding
multicast forwarding table entry, wherein the RPF interface in an output interface
list in the generated multicast forwarding table entry is the RPF interface which corresponds to the matched DF election example. By the method and the equipment, multicast
load sharing can be realized by using equivalent routing.
