Estimating the Number of Routes
By default, DVMRP preallocates a routing table for 25 entries. You can use the
BCC or Site Manager to specify the number of entries (10 or more).
For an MBone implementation, a value of 3,000 or higher is recommended.
Using the BCC
Navigate to the DVMRP global prompt and enter:
estimated-routes
<route>
route
is an integer (10 or greater) indicating the estimated number of entries
needed in the routing table.
For example, the following command causes DVMRP to preallocate space for a
routing table with 50 entries:
dvmrp#
estimated-routes 50
dvmrp#
