We will need to set up a L2TPV3 tunnel to their old location (single
homed, no BGP on that side). Upon initial reading of Cisco docs to do
this, we will need a routable IP on a loopback interface for starters.
Also, like any other tunnel, beware of MTU issues, these are so
routinely

From a VZ IP circuit that I have:
interface Loopback0
ip address x.x.x.x 255.255.255.255 (actual assigned mask is 255.255.255.252)
interface Serial0/0/0
bandwidth 1536
ip unnumbered Loopback0
ip route 0.0.0.0 0.0.0.0 Serial0/0/0
Works great for me

Yeah, it's evil. I don't see a cisco equiv to state it's point to point
(you can tell ISIS it is, but not define the interface as such).
However, I'm not sure of the limitations or associated
It is L2TPv3 I think that Sprint is using for there MPLS offer and
Sprint Link Frame Service.

Agreed: We used to use L2TPv3 tunnels
fairly often to provide nailed-up private VLAN services to
clients when we could only procure a Layer 3 circuit
A simpler question(s) than it sounds:
Customer just brought up their first BGP session at a new location. It is
up fine with a full routing table, the second provider hookup is a few
weeks away.
The provider allocated a /24 (x.x.1.0/24) for the network and a /30 for
the PTP connection

I'm pretty sure this is just a recommendation based on good practise

interface WAN1 (actually a gigether)
ip unnumbered loopback0 (or no ip addr?)
That's not correct.
Actually, was fixating on the fact that he has ethernet WAN and last I
checked IOS doesn't have unnumbered-to-ethernet capability (well not true,
recently they introduced unnumbered SVI
