Trouble with IPv6 setup on Quagga

Most likely the trouble you're having is bgpd being unable to reference
zebra RIB via socket.
Make sure zebra is running and that your next-hop is visible as directly
connected when doing 'sh ipv6 route' under zebra vty.

Subject: Trouble with IPv6 setup on Quagga
I am having trouble with Quagga in setting up IPv6 BGP. So far it was
failing with external providers. Just now I gave it a try to setup BGP
session (IPv6 only) within our ASN between two routers.
>From our other end router I see there is no acconcement, while I see
being announced via Quagga. Also strange enough is that the number of blocks
I account - they all come as "withdrawl routes" on other router as soon as
Quagga is turned on.
E.g this is what I see on Quagga:
node4# show bgp ipv6 summary
BGP router identifier 126.96.36.199, local AS number 54456 RIB entries
18741, using 1757 KiB of memory Peers 1, using 4560 bytes of memory
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down
4 54456 6865 5 0 0 0 00:00:05 9798
Total number of neighbors 1
So BGP session is up. Next if I check advertised routes, it goes like:
node4# show bgp ipv6 neighbors 2607:1b00:10:a::1 advertised-routes BGP
table version is 0, local router ID is 188.8.131.52 Status codes: s
suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale, R Removed Origin codes: i - IGP, e -
EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
:: 0 100 32768 i
:: 0 100 32768 i
Total number of prefixes 2
I don't see these routes in other router at all.
Here's what my Quagga bgpd.conf looks like:
timers bgp 4 16
router bgp 54456
bgp router-id 184.108.40.206
redistribute connected metric 1
redistribute static metric 1
neighbor 2607:1b00:10:a::1 remote-as 54456 neighbor 2607:1b00:10:a::1
neighbor 2607:1b00:10:a::1 activate
Was wondering if someone can point in me right direction since both of these
prefixes are (annnounced and ?) withdrawn as soon as I restart Quagga.
