In configuring and using DVMRP Protocol, DVMRP Protocol might not operate
normally caused by physical connection or incorrect configuration. Therefore, the user
should pay attention to the following issues:
z
Firstly to assure that physical connection is correct.
z
Next, to assure the Protocol of Interface and Link is UP (use show interface
command);
z
Please check if the correct IP address is configured on the interface (use ip address
command)
z
Afterwards, enable DVMRP Protocol on the interface (use ip dvmrp command and ip
dv multicast-routing
command)
z
Multicast Protocol requires RPF Check using unicast routing; therefore the
correctness of unicast routing must be assured beforehand.(DVMRP uses its own
unicast table, please use show ip dvmrp route command to look up);
If all attempts including Check are made but the problems on DVMRP can’t be
solved yet, then please use commands such as debug dvmrp, and then copy DEBUG
information in 3 minutes and send to Technology Service Center.
