[c-nsp] BGP doesn't advertise prefixes

[Samol]

Hi All,

Thanks for the recommended so far. I just found this issue is also
happening to our IPv6 peer. This is even straight configuration.

- *route-map attached to peer*

RTR#sh bgp ipv6 unicast neighbors 2404:xxxx:3001:D::1 | in Route
    Route refresh: advertised and received(new)
    Route Refresh:          1          0
  Route map for incoming advertisements is EQUINIX-TRANSIT-V6-IN
  Route map for outgoing advertisements is EQUINIX-TRANSIT-V6-OUT

*- route-map rule*

RTR#sh route-map EQUINIX-TRANSIT-V6-OUT
route-map EQUINIX-TRANSIT-V6-OUT, permit, sequence 10
  Match clauses:
     ipv6 address prefix-list CP-V6-BLOCKS
  Set clauses:
  Policy routing matches: 0 packets, 0 bytes

*- prefix-list to match the route to advertise*

RTR#sh ipv6 prefix-list CP-V6-BLOCKS
ipv6 prefix-list CP-V6-BLOCKS: 1 entries
   seq 10 permit 2402:xxxx::/32

*- bgp ipv6 table, update group 4 is not our peer we want here*

RTR#sh bgp ipv6 unicast 2402:xxxx::/32
BGP routing table entry for 2402:xxxx::/32, version 4908
Paths: (1 available, best #1, table Default)
  Advertised to update-groups:
     4
  Local
    :: from 0.0.0.0 (x.x.x.1)
      Origin IGP, metric 0, localpref 100, weight 32768, valid, sourced,
local, best

*- v6 route match with route-map *

RTR#sh bgp ipv6 unicast route-map EQUINIX-TRANSIT-V6-OUT
BGP table version is 31743384, local router ID is x.x.x.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
              r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path
*> 2402:xxxx::/32   ::                       0         32768 i

*- but nothing advertise out !*

RTR#sh bgp ipv6 unicast neighbors 2404:xxxx:3001:D::1 advertised-routes

Total number of prefixes 0

Any idea is really appreciated...
