Can't update IPv6 routes

Hi, I have been trying to publish routes to a router 2001:db8::1 which is connected via IPv6. The PC pushing the routes is 2001:db8::2. My neighborship is established and I can confirm that on the router. However, I am not getting those updates on the router. Can you point out if I am missing out anything here? This is my ban2bgp.ini file.

[main]
httplisten=0.0.0.0:8080
listen=0.0.0.0:1179
nexthop6=2001:db8::2
communities=666:666
peers=peer_r1 
duration=3600
skiplist=2001:db8::1/64

[peer_r1]
peer=2001:db8::1
localas=65535
as=33771
mode=blackhole
