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).
