Figure 40-6 Leaf Nonpruning DVMRP Neighbor
You can prevent the switch from peering (communicating) with a DVMRP neighbor if that neighbor does
not support DVMRP pruning or grafting. To do so, configure the switch (which is a neighbor to the leaf,
nonpruning DVMRP machine) with the ip dvmrp reject-non-pruners interface configuration command
on the interface connected to the nonpruning machine as shown in Figure 40-7. In this case, when the
switch receives DVMRP probe or report message without the prune-capable flag set, the switch logs a
syslog message and discards the message.
