DVMRP
Note that the ip dvmrp reject-non-pruners interface configuration command prevents peering with
neighbors only. If there are any nonpruning routers multiple hops away (downstream toward potential
receivers) that are not rejected, a nonpruning DVMRP network might still exist.
Beginning in privileged EXEC mode, follow these steps to prevent peering with nonpruning DVMRP
neighbors. This procedure is optional.
