Figure 7-30. DVMRP Interface Configuration screen
Items on the screen above include:
•
Interface Name
– The name of the IP interface (previously defined) on the Switch for which a multicast
interface is to be configured.
• IP Address – The IP address (sometimes referred to as a network address) corresponding to the interface
name above.
• Probe Interval
– This field allows an entry between 0 and 65,535 seconds and defines the interval between
‘probes’. The default is 10. DVMRP defines an extension to IGMP that allows routers to query other routers to
determine if a multicast group is present on an given IP interface or not.
• Neighbor Time-Out Interval
– This field allows an entry between 1 and 65,535 seconds and defines the
time period for which DVMRP will hold Neighbor Router reports before issuing poison route messages. The
default is 35 seconds.
•
Route Metric
– Allows the assignment of a DVMRP route cost to the above IP interface. A DVMRP route
cost is a relative number that represents the real cost of using this route in the construction of a multicast
delivery tree. It is similar to, but not defined as, the hop count in RIP. The default value is 1.
• Include Unknown Neighbor Report – Allows the Layer 3 switch to accept a DVMRP route report from a
non-adjacent neighbor.
• State
– Allows DVMRP to be
Disabled
or
Enabled
for the above IP interface. The default is
Disabled
.
PIM-DM Interface Configuration
The following window is used to configure a Protocol Independent Multicast - Dense Mode (PIMDM) interface on the Switch
(Layer 3 mode only).
