[c-nsp] IPv6 filters

[Scott Voll]

New to IPv6 so sorry if this is a very basic question:

I currently am dual homed with ipv4

I'm currently using a filter list:

ip as-path access-list 1 permit ^$
ip as-path access-list 1 deny .*

to make sure I'm not a transit provider.

in my googleing around I'm not seeing that done in IPv6

Looks Like I should be putting together prefix list instead.  is that the
best practices in IPv6?

Thanks

Scott
