[j-nsp] How to examine a prefix in all routing instances

[wang yi]

Hi,

Is there a way to check whether a particular prefix is present in the inet.0
of all the routing instances of a router? I am doing

show route 10.0.1.0/24 table l3vpn1.inet.0
show route 10.0.1.0/24 table l3vpn2.inet.0
:
:
show route 10.0.1.0/24 table l3vpn99.inet.0

The routing instance name is quiet long and there are sometimes more than 20
layer 3 vpns. BTW, what is the max. routing-instance supported in 8.2?

thanks

yi
