CISCO-IP-URPF-MIB Table View

This table contains summary information for the
managed device on URPF dropping.

cipUrpfEntry row .1.3.6.1.4.1.9.9.451.1.2.1.1

If the managed device supports URPF dropping,
a row exists for each IP version type (v4 and v6).
A row contains summary information on URPF
dropping over the entire managed device.
