16.4.3.2 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 metric 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 entries from the interface adding configured
interface metric value as new metric value of the routing. The metric value applies to
calculate poison 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 judgment, 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
16.4.3.3 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
16.4.3.4 ip dvmrp output-report-delay
Command: ip dvmrp output-report-delay <delay_val> [<burst_size>]
no ip dvmrp output-report-delay
Function:
Configure the delay of DVMRP report message transmitted on interface and
transmitted message quantity every time, the “
no ip dvmrp output-report-delay
”
