Input packets: 0

Protocol inet, Generation: 144, Route table: 0
Flags: uRPF
Addresses, Flags: Is-Preferred Is-Primary
Meaning The show interfaces ge-1/0/10 extensive command (and the show interfaces ge-1/0/10
detail command) displays in-depth information about the interface. The Flags: output
field near the bottom of the display reports the unicast RPF status. If unicast RPF has
not been enabled, the
uRPF
flag is not displayed.
On EX3200 and EX4200 switches, unicast RPF is implicitly enabled on all switch
interfaces, including aggregated Ethernet interfaces (also referred to as link aggregation
groups or LAGs) and routed VLAN interfaces (RVIs) when you enable unicast RPF on a
single interface. However, the unicast RPF status is shown as enabled only on interfaces
for which you have explicitly configured unicast RPF. Thus, the
uRPF
flag is not displayed
on interfaces for which you have not explicitly configured unicast RPF even though unicast
RPF is implicitly enabled on all interfaces on EX3200 and EX4200 switches.
