8-port Gigabit Ethernet Switch User's Guide 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). 167
