Good morning!

Something like this should work.

configure bgp AS-number 12345
configure bgp add network
configure bgp add network address-family ipv6-unicast 2001:db8:1000:/48

create bgp neighbor remote-AS-number 1000
configure bgp neighbor source-interface ipaddress
create bgp neighbor 2001:db8:f00::2 remote-AS-number 1000
configure bgp neighbor 2001:db8:f00::4 source-interface ipaddress 2001:db8:f00::5
enable bgp neighbor
enable bgp neighbor 2001:db8:f00::4 address-family ipv6-unicast
enable bgp

Assuming you have a "Provider" vlan:

create vlan BigISP tag 999
configure vlan BigISP ipaddress
configure vlan BigISP ipaddress 2001:db8:f00::/64

Oh, and get used to adding "address-family ipv6-unicast" to pretty much any command where you want to see ipv6 output ;) (OK, I'm exaggerating a little - tab-completion and the "?" are your friend on the command line)

Hope that helps
