Hi Andrew,

Nope, it is not hidden. rc1 does not receive it at all.

Here is the output show from rr and rc1:
=======================================================
rr advertise the routes to rc1
show route advertising-protocol bgp 10.1.1.81 table bgp.l3vpn.0

bgp.l3vpn.0: 51 destinations, 107 routes (51 active, 0 holddown, 0
hidden)
  Prefix                  Nexthop              MED     Lclpref    AS
path
  65232:900100:150.85.0.0/16
*                         10.2.2.19	           0       100        ?
  65232:900100:192.168.0.0/16
*                         10.2.2.19            0       100        ?
  65232:900100:192.168.1.0/24
*                         10.2.2.19            0       100        ?


BUT rc1 doesn't receive it at all.

show route receive-protocol bgp 10.1.1.4 table bgp.l3vpn.0 all

bgp.l3vpn.0: 0 destinations, 0 routes (0 active, 0 holddown, 0 hidden)

========================================================================
====
=

and definetely we can reach the next-hop:
ping 10.2.2.19
PING 10.2.2.19 (10.2.2.19): 56 data bytes
64 bytes from 10.2.2.19: icmp_seq=0 ttl=254 time=1.479 ms

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...).
