[f-nsp] MLXe BGP Next Hop Not Reachable

[James Cornman]

Hello,

Came across a strange issue that I could use a second set of eyes on.

Have an MLXe8 router with 5.6e running.  Customer BGP session is up and
we're receiving the route they're advertising, but BGP thinks the next-hop
is unreachable and not accepting the route. Its not even getting to the
point of processing any prefix-lists or route-maps.


SSH at router#show ip bgp neigh 10.60.154.210 received-routes detail
       There are 1 received routes from neighbor 10.60.154.210
Searching for matching routes, use ^C to quit...
Status A:AGGREGATE B:BEST b:NOT-INSTALLED-BEST C:CONFED_EBGP D:DAMPED
       E:EBGP H:HISTORY I:IBGP L:LOCAL M:MULTIPATH m:NOT-INSTALLED-MULTIPATH
       S:SUPPRESSED F:FILTERED s:STALE
1       Prefix: 10.60.158.0/26,  Status: EF,  Age: 0h0m12s
         NEXT_HOP: 10.60.154.210, Not Reachable, Learned from Peer:
10.60.154.210 (64585)
          LOCAL_PREF: 100,  MED: 0,  ORIGIN: igp,  Weight: 0
         AS_PATH: 64585


interface ve 170
 ip address 10.60.154.209/29
!

 neighbor CUSTOMER-ABC peer-group
 neighbor CUSTOMER-ABC remote-as 64585
 neighbor CUSTOMER-ABC soft-reconfiguration inbound
 neighbor CUSTOMER-ABC default-originate
 neighbor CUSTOMER-ABC route-map in CUSTOMER-NOEXPORT-in
 neighbor CUSTOMER-ABC route-map out DEFAULT-ONLY
 neighbor 10.60.154.210 peer-group CUSTOMER-ABC

Tried the usual suspects of removing the interconnect /29 from the ve and
re-applying, rebuilding the BGP session, bouncing it many times, etc.
Session is up..ping communication works fine.
