I faced an interesting problem today. In a customer L3VPN/VRF a route was hidden
and it was not apparent why. In JunOS when you do a show route ... command you
will get a summary at the top that tells you some statistics. In this case, four
routes are hidden (three were expected, the one displayed here should not have
been hidden). You can display hidden routes by adding the hidden option to the
show route command:
user@core1> show route table customer-vrf.inet.0 10.1.2.0/22 hidden
customer-vrf.inet.0: 31 destinations, 34 routes (30 active, 0 holddown, 4 hidden)
+ = Active Route, - = Last Active, * = Both
10.1.2.0/22 [BGP ] 1d 17:20:31, MED 0, localpref 100, from 198.51.100.27
AS path: 65003 ?, validation-state: unverified
to 198.51.100.174 via ae1.0, Push 16, Push 300928(top)
> to 198.51.100.66 via ae17.0, Push 16, Push 302608(top)
