Command Mode:
Interface Configuration Mode
Usage Guide:
The interface processes DVMRP protocol messages, only excuting
DVMRP protocol on interface.
Example:
Enable DVMRP Protocol on interface vlan1.
Switch (Config)#interface vlan 1
Switch(Config-If-vlan1)#ip dvmrp
17.4.3.2 ip dvmrp metric
Command: ip dvmrp metric
<metric_val>
no ip dvmrp metric
Function:
Configure interface DVMRP report message metric value; the “
no ip dvmrp
metric
” command restores default value.
Parameter: <metric_val>
is metirc value, value range from 1 to 31
Default:
Default: 1
Command Mode:
Interface Configuration Mode
Usage Guide:
The routing information in DVMRP report messages includes a
groupsource network and metric list. After configuring interface DVMRP report message
metric value, it makes all received routing entriy from the interface adding configured
interface metric value as new metric value of the routing. The metric value applies to
calculate posion reverse, namely ensuring up-downstream relations. If the metric value of
some route on the switch is not less than 32, it explains the route can be reach. If it is
downstream of some route after calculation and judgement, it will transmit report
message included the route to upstream. The route metric increases 32 based on original
value in order to indicate downstream itself.
Example:
Configure interface DVMRP report message metric value: 2
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip dvmrp metric 2
17.4.3.3 ip dvmrp multicast-routing
Command: ip dvmrp multicast-routing
no ip dvmrp multicast-routing
Function:
Globally enable DVMRP protocol; the “no ip dvmrp multicast-routing” command
globally disenables DVMRP protocol
Parameter:
None
Default:
Defalut
Command Mode:
Global Mode
Usage Guide:
Dvmrp multicast-protocol can enable after globally execute the command
Example:
Switch (Config)#ip dvmrp multicast-routing
