[j-nsp] Missing routes in bgp.l3vpn.0 table

[Douglas Marschke]

Two things to look for:

1)Is the proper route target configured?  (import rc1 matches rc2
export)
2)As andrew said, do you have a route in inet.3 to rc2.  If you do not,
routes will show up as hidden.

Hi,

Does client1 not receive them or does it receive them, but they are
hidden?  Common cause of the latter would be that client1 doesn't have a
"usable" next-hop to the RR (no LSP, etc...).
