Configuring a Forwarding Table

To minimize the amount of time that it spends looking up routes, DVMRP creates

and maintains a cache of frequently used routes -- called a forwarding table -- for

each IP interface.

By default, DVMRP preallocates a forwarding table of 32 entries for each circuit.

You can use Site Manager to specify the maximum number of entries (32 to 512)

allowed in the forwarding table associated with this circuit.

When configuring a cache size, you must also keep in mind the TTL value for

entries. If you specify a large cache size, you can specify a larger TTL value. A

smaller cache requires a smaller TTL for cache entries.
