Hy Jeff,

We have a Metro Network with 3750Stacks, Vlan in between, Vrf Life on the Boxes, EIGRP ans Core Routing Protocol,.... 

Works quite well aslong you don't do special things like Multicast (cisco meand: not recomendet on this Setup ;-)), Advanced QOS (Box has just 4 Hardware Ques, 3 Treshholds...) etc... 

As we have a ring topoplogy the configuration is guite complex... Even if you don't need the vrf at the location you have to at least span the vlan all over the ring....

If you can i would go for a "real" MPLS solution - we start to migrate very soon ;-)

If you need more information just drop me a mail....

Anyone running a 3750 or 4500 as a PE router (nothing fancy, just
inter-VRF iBGP that really "imports/exports" routes)?

We have a VRF-lite network but at this point only one iBGP mesh point
(PE).  There are cases where some of the nodes attached to the current
PE could ideally route between VRFs locally without spitting it out to
the PE and back.  In our case we have a "core services" VRF that is
essentially imported into every VRF.  It's a straight shot across the
core IX subnet if I could put the "core services" presence on some of
the CEs rather than the extra hop to route through the core.

Trying to avoid statics...
