I remember reading about PVST in my notes, but I don't think it's the right answer for this specific case.

I practiced a similar question last week, and I believe the answer was 802.1D 1998, but I'm not entirely sure.

I vaguely recall that comp-dot1w might be related, but I don't think it's the default for VPLS.

I think the default protocol for VPLS on the 7750 SR is 802.1D, but I can't remember if it's the 1998 or 2004 version.
