Monitoring DVMRP Routes

Purpose

Display information about DVMRP routes.

You can specify an IP address to display the best route to that address or specify an IP address and subnet mask to display the route that exactly matches this IP address and subnet mask. You can use the brief keyword to view a summary of information. You can specify an interface type and specifier to display routes associated with that interface. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide.

Action

To display information about DVMRP routes:

host1:boston>show ip dvmrp route 
Prefix/Length        usNbr/Owner       Metric ExpireTime UpTime Interface
  14.0.0.0/8         Dvmrp Local          1      Never     18   atm5/0.14
    Downstream Interface(s)
        Interface
        atm5/0.15
  15.0.0.0/8         Dvmrp Local          1      Never     18   atm5/0.15
    Downstream Interface(s)
        None
  25.0.0.0/8         14.0.0.1             2        129     11   atm5/0.14
    Downstream Interface(s)
        Interface
        atm5/0.15

To display a summary of information about DVMRP routes:

host1:v3# show ip dvmrp route brief
  Prefix/Length      usNbr/Owner       Metric ExpireTime UpTime Interface
  14.0.0.0/8         Dvmrp Local          1      Never     26   atm5/0.14
  15.0.0.0/8         Dvmrp Local          1      Never     26   atm5/0.15
  25.0.0.0/8         14.0.0.1             2        121     19   atm5/0.14
