Figure 7-32. 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).
