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.
By default, DVMRP assigns a TTL value of 7200 seconds to an entry in a tunnel
forwarding table. You can use Site Manager to assign a value from 300 to 86400
seconds.
