bgp load balance and ipv6 radvd

[HL]

Hello,

I am watching this project for a year now and I Feel that it's time to 
try some of its features

I have 2x2811 cisco connected to the isps

Behind them I have a linux box running shorewall firewall and
wish to have some routing daemon to manage fail over and load ballancing 
...

cisco 1 is confed as
-------------------------------------
!
router bgp 12
  no synchronization
  bgp router-id xx.xx.xx.xx
  bgp log-neighbor-changes
  network 0.0.0.0
  redistribute connected
  neighbor 10.0.11.2 remote-as 10
  auto-summary
!
------------------------------------------
cisco 2 as
!
router bgp 11
  no synchronization
  bgp router-id xx.xx.xx.xx
  bgp log-neighbor-changes
  network 0.0.0.0
  redistribute connected
  neighbor 10.0.12.2 remote-as 10
  auto-summary
!
---------------------------------------------
The linux BOX is running an old version of quagga bgp soon to be updated
current config is

-----------------------------------------------------------
Current configuration:
!
hostname bgpd
log stdout
!
router bgp 10
  bgp router-id 10.0.173.254
  bgp log-neighbor-changes
  network 10.0.173.0/24
  network 10.168.1.0/24
  network xx.xx.xx.xx
  network xx.xx.xx.xx
  neighbor 10.0.11.1 remote-as 12
  neighbor 10.0.11.1 weight 100
  neighbor 10.0.11.1 soft-reconfiguration inbound
  neighbor 10.0.11.1 route-map rm_peer_1_in in
  neighbor 10.0.12.1 remote-as 11
  neighbor 10.0.12.1 weight 50
  neighbor 10.0.12.1 soft-reconfiguration inbound
  neighbor 10.0.12.1 route-map rm_peer_2_in in
!
route-map rm_peer_1_in permit 5
  set local-preference 100
!
route-map rm_peer_2_in permit 5
  set local-preference 100
!
line vty
!
end

Ok so far so good ...

Can I achieve the load balancer and fail over with bird with a conf like 
the above ...
If yes that is Great cause here comes Q2

Q2
One of the isp's is giving me a /64 ipv6 dynamic prefix ....

Since I thought I saw some radvd daemon included in bird ...

Can radvd be confed to break this dynamic ipv6 and distribute it to the 
internal zones and network ???

Thanx in advance.
Regards
Harry.
