To configure broadcast and multicast addresses to be used by the frame relay

switch, complete the following tasks:

Specifying the Maximum Size of the Forwarding Table

To minimize the amount of time it spends looking up routes, IP creates and

maintains a cache of frequently used routes — called a forwarding table or cache

— for each IP interface. A forwarding table is a first in first out (FIFO) buffer.

When a datagram arrives on an IP interface for forwarding, IP searches the

forwarding table associated with the interface for the destination network. If the

search is successful, IP dispatches the datagram to the interface noted in the table

entry.

If the search is unsuccessful, IP consults the routing table to obtain the same

information, dispatches the datagram to the appropriate interface, and caches the

information in the appropriate forwarding table, either by appending information

to the table (if the table is not full) or by overwriting the oldest, first-in table entry

(if the table is full).
