Re: ospf area authentication - virtual-links

The VL will transit area 1, but it is not an area 1 interface. So no.

If you had area 0 authentication on other (normal area 0 routers) turned
on, then you would also need to do so on both sides of the VL but
specifically for the virtual link command not physical interfaces.
