Multicast Routing Tables
Multicast routing builds on unicast routing. Each multicast group to which the local router can route has a multicast routing table entry with a next hop for the group, rather than for a specific destination as in unicast routing.
There can be multicast static routes as well as learning dynamic multicast routes from a protocol such as Protocol Independent Multicast (PIM).

Famous quotes containing the word tables:
“The evening falters. Couples in their coats
Are leaving gaps already, and the rest
Move tables closer.”
—Philip Larkin (1922–1986)
