[alcatel-nsp] VPRN with BGP route redistribution problem

I'm trying to get a L3VPN working and use BGP as the PE-CE protocol. Somehow
I can't get the routes which I learn over a global L3VPN BGP session to be
announced to the CE over BGP. Must be missing something in my configuration
The routes are learned correctly from the other side PE and they are in my
local routing table (I can see them with "SHOW ROUTER xxxxx ROUTE-TABLE"):
Route Table (Service: xxxxx)
======================================================
Dest Prefix Type Proto Age
Pref
Next Hop[Interface Name]
Metric
-------------------------------------------------------------------------------
[...]
y.y.y.y/24 Remote BGP VPN 00h00m45s
170
z.z.z.z (tunneled) 0
[...]
However, the route is not announced to my direct BGP peer over the direct
session.
Here is my vprn configuration:
service
vprn 10 customer 1 create
autonomous-system 11111
route-distinguisher 11111:22222
auto-bind ldp
vrf-target target:11111:22222
interface "ce0-vlan801" create
address x.x.x.1/24
sap 8/1/1:801 create
exit
exit
bgp
router-id x.x.x.1
group "ce1"
type external
peer-as 22222
neighbor x.x.x.2
exit
exit
exit
no shutdown
exit
exit
What do I miss? Do I need some import of the routes from the vrf table into
bgp? Tried a few versions, but failed on all of them. BGP is all up and fine
and all the learned routes from the CE are imported and sent to the other
side just fine, just the routes learned over the vpn bgp session are only
making it into the local service routing table and are not announced to the
CE router.
Any hints?
