For doing what?

Running OSPFv3?
ipv6 router ospf 1234

If you want something more relavent, you'll have to tell us what you
are trying to accomplish.

Okay, you don't broadcast an AS number.

You can BGP announce a netblock, originating from your AS. The AS
number is just a unique ID used to talk BGP with your upstream peers,
it has no more signifigance than an ID number.

If you don't have any netblocks to announce, there's nothing really that
you can do with an AS number.

If you do have a netblock that needs to be BGP announced, and want to
start doing BGP, you'll first need to talk to your upstream about
becoming a BGP peer with them and what you want to do. Most likely
they will need to know what netblock and AS number you will be
announcing it from in order to setup the filtering that they will most
likely implement, or setup inside some sort of RRDB that they generate
their filters from. You'll also want to figure out if you are doing
BGP authentication with your upstream peer and what the key should be.

Assuming that your upstream doesn't just do the BGP announcement for
you, and that you want to do it..

A simple BGP setup would be something like

router bgp 1234
no synchronization
bgp log-neighbor-changes
bgp dampening
network 10.0.0.0/24
neighbor 11.0.0.1 remote-as 4321
neighbor 11.0.0.1 password oooooooohh
neighbor 11.0.0.1 version 4
neighbor 11.0.0.1 prefix-list my_netblocks out

ip prefix-list my_netblocks description Our allowed routing announcements
ip prefix-list my_netblocks seq 5 permit 10.0.0.0/24
ip prefix-list my_netblocks seq 10 deny 0.0.0.0/0 le 32


But, you'll need to talk to your upstream about much of this as well.
