BGP next-hop self and labeled unicast route

Hi all:

 

I have an external BGP labeled-unicast  session working fine and I suppose to receive a route of 192.168.111.3:

 

user@london# run show bgp summary                      
Groups: 3 Peers: 3 Down peers: 0
Table          Tot Paths  Act Paths Suppressed    History Damp State    Pending
inet.0                 0          0          0          0          0          0
inet.3                 2          0          0          0          0          0
Peer                          AS             InPkt     OutPkt    OutQ   Flaps Last Up/Dwn State|#Active/Received/Accepted/Damped...
192.168.100.1        65500       86         86            0         1       37:19 Establ
  inet.3: 0/1/1/0
192.168.100.2        65500       4488     4473       0         0  1d 9:46:09 0/0/0/0              0/0/0/0
192.168.111.1        65501       85         83            0         0       36:09 Establ
  inet.3: 0/1/1/0

 

But due to the next-hop issue, the route I received is hidden:

 

user@london# run show route table inet.3 hidden   

inet.3: 12 destinations, 13 routes (10 active, 0 holddown, 2 hidden)
+ = Active Route, - = Last Active, * = Both

127.0.0.1/32             [Direct/0] 01:01:18
                                   > via lo0.0
192.168.111.3/32   [BGP/170] 00:38:47, localpref 100, from 192.168.111.1
                                   AS path: 65501 I
                                   Unusable

 

 

user@router# run show route resolution unresolved             
Tree Index 1
192.168.111.3/32
        Protocol Nexthop: 192.168.111.1 Push 100224
        Indirect nexthop: 0 -
Tree Index 2
Tree Index 3
Tree Index 4

 

So how could I reset the next-hop for this labeled route?

Re: BGP next-hop self and labeled unicast route

according to statements from juniper document:

 

"When the labeled-unicast statement is used, the local router automatically performs a next hop to self on all routes advertised into the external BGP (EBGP) from the internal BGP (IBGP) and from IBGP to EBGP"

 

it doesn't seem to be case as far as I can tell, unless the knob "resolve-vpn" being used.

Re: BGP next-hop self and labeled unicast route

never mind, the statement is correct.
