Hi,

My lab config:

context BGP

  community-list REDIRECT
   seq 10 permit 65000:667

  route-map rm-in permit 200
   match community-list REDIRECT
   set ip next-hop 192.168.99.89

  route-map rm-out deny 10

   neighbor 192.168.12.184 external
     remote-as 65000
     address-family ipv4 unicast
       route-map rm-in in
       route-map rm-out out

  ip route 192.168.99.89/32 context FILTER

context FILTER

  interface int1
   ip address 192.168.99.89/30

  ip route 0.0.0.0/0 192.168.99.90


First step I'm marking IP 93.179.215.2 with community 6500:667

BGP#show bgp route 93.179.215.2/32
BGP ipv4 unicast routing table entry: 93.179.215.2/32, version 0
Paths: total 1, best path count 0, best peer 0.0.0.0
Not downloaded to RIB (no bestpath)
Not advertised to any peer

65000
   Nexthop 192.168.99.89 (inaccessible), peer 192.168.12.184 
(192.168.12.184), AS 65000
   Origin IGP, localpref 100, med 0, weight 100, external
   Community: 65000:667

Problem:
next-hop 192.168.99.89 is inaccessible


Question:
How can I solve issue with inaccessible next-hop to FILTER context?


PS: IP 192.168.99.90/30 is interface on PC with running tcpdump but 
there is no incomming traffic.
