Hi, folks.
I am trying to configure CYMRU BOGONS server like described in this
guide: http://www.cymru.com/BGP/bogon-rs.html
I am using Cisco router example and on my cs3550 everything is fine.
However in case of BigIron8000 this routes is unreachable:

sh ip bgp neighbor 38.229.0.5 routes-summary
1   IP Address: 38.229.0.5
Routes Accepted/Installed:61,  Filtered/Kept:0,  Filtered:0
   Routes Selected as BEST Routes:0
      BEST Routes not Installed in IP Forwarding Table:0
   Unreachable Routes (no IGP Route for NEXTHOP):61
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   History Routes:0

NLRIs Received in Update Message:61,  Withdraws:0 (0),  Replacements:0
   NLRIs Discarded due to
      Maximum Prefix Limit:0, AS Loop:0
      Invalid Nexthop:0, Invalid Nexthop Address:0.0.0.0
      Duplicated Originator_ID:0, Cluster_ID:0

Routes Advertised:0,  To be Sent:0,  To be Withdrawn:0
NLRIs Sent in Update Message:0,  Withdraws:0,  Replacements:0

Peer Out of Memory Count for:
   Receiving Update Messages:0, Accepting Routes(NLRI):0
   Attributes:0, Outbound Routes(RIB-out):0 Outbound Routes Holder:0

So routes was not installed in routing table.

Here is additional info:

telnet at fbi8000-Border-NY#sh ip bgp neighbor 38.229.0.5 routes
       There are 61 accepted routes from  neighbor 38.229.0.5
Searching for matching routes, use ^C to quit...
