Trunking issue between CE switch and PE router after configuring vrf.

I'm fairly certain this should have just been a simple Router on a Stick configuration. But I cannot figure out why I can't ping across my trunk. Vlan is up, trunking is up, interface is up on both ends, ip addresses are the same prefix. My topology, the first image is how I have it setup in GNS3
