44.7.7 ip dvmrp tunnel
Command:
ip dvmrp tunnel <index> <src-ip> <dst-ip>
no ip dvmrp tunnel {<index> |<src-ip> <dst-ip>}
Function:
Configure a DVMRP tunnel; the “no ip dvmrp tunnel {<index> |<src-ip> <dst-ip>}” command
deletes a DVMRP tunnel.
Parameter:
<src-ip> is source IP address,
<dst-ip> is remote neighbor IP address,
<index> is tunnel index number, value range from 1 to 65535.
Default:
Do not Configure DVMRP tunnel.
Command Mode:
Global Mode
Usage Guide:
Because not all of switches support multicast, DVMRP supports tunnel multicast communication.
The tunnel is a way of transmitted multicast data packet among DVMRP switches partitioned off
switches without supporting multicast routing. It acts as a virtual network between two DVMRP
switches. Multicast data packets packed in unicast data packets, directly are transmitted to next
supporting multicast switch. DVMRP protocol equally deal with tunnel interface and general
physical interface. After configuring no ip dv multicast-routing, all of the tunnel configurations are
deleted.
Example:
Switch(config)#ip dvmrp tunnel 1 12.1.1.1 24.1.1.1
44.7.8 show ip dvmrp
Command:
show ip dvmrp
Function:
Display DVMRP protocol information.
Default:
Do not display (Off)
Command Mode:
