1) A CE router will be configured as any normal WAN router where you peer with the SP router. The CE router has no knowledge of MPLS or MPLS VPN's, it just peers with the SP PE router. What you do need to do is agree with your SP as to how your CE and their PE will peer ie. with static routes/EIGRP/OSPF/BGP.

2) Yes

3) As mentioned you need to agree how your CE and their PE will exchange routes and you obviously need IP addresses for your CE -> PE link.

HI, [Pls Rate all Informative POST]

In addition to JON POST,

In a Normal Scenario, the VRF tagging will be added from the SP PE Interface and the same will be stripped OFF once it's getting out of SP Cloud.

The VRF Labels are maintained inside the SP Cloud, since VRF has Unique routing instance over the Global IP Routing Table.

In addition, for any MPLS Customer between PE - CE a /30 Private Segment will be assigned by SP for the WAN Interfaces.

Running a Static Routes or any DYNAMIC Protocol on the LAST MILE is based on the aggrement between the SP and the Customer.

Hope I am Informative.

Do Rate all Informative POST

Best Regards,
