[c-nsp] Basic question on 6509 switchport module

Hi Rick,

I think it depends whether you want to have multiple ports in the same
subnet then you can configure a SVI (vlan interface) and assign the ports in
that vlan (12 in your case). If you wished to create routed ports then all
the AS52000 would have to be in their own subnet (2.2.2.8/30, 2.2.2.12/30 ,
etc. )

So looks good to me :)

Cheers,
Vincent
