• Route Metric:[1 ] – This field allows an entry between 1 and 255 and defines the route cost for the IP
interface. The DVMRP route metric 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 cost
is 1.
Note: Route metric is a relative number that is used by DVMRP to calculate which branches of a
multicast delivery tree should be ‘pruned’.
Note: The higher the route cost, the lower the probability that the current route will be chosen to be an
active branch of the multicast delivery tree (not ‘pruned’) – if there is an alternative route.
• Probe Interval:[10 ] – This field allows an entry between 1 and 65,535 seconds and defines the interval
between ‘probes’. The default is 10.
• State:<Disabled> – Toggle between Enabled and Disabled to enable or disable DVMRP for the IP interface.
The default is Disabled.
• Include Unknown Neighbor Report:<Disabled> – Allows the Layer 3 switch to accept a DVMRP route
report from a non-adjacent neighbor.
PIM-DM Interface Configuration
To configure PIMDM for an IP interface:
Highlight PIMDM Interface Configuration from the IP Multicasting Settings menu and press Enter.

• Interface Name:[ ] – Enter the name of the IP interface for which PIM-DM is to be configured in this field.
This must be a previously defined IP interface. See Setting up IP Interfaces in Chapter 6 of this manual for
more information.
