>> Although we've done several MPLS VPNs in the past, we've always used BGP as the PE-CE routing protocol. Now, I have a new customer that wants to use EIGRP instead. The configuration doesn't seem too hard, but something isn't working correctly:
>> 
>> 
>> -          We are learning routes from the customer at each location (2 currently, with more to follow)
>> 
>> -          PE1 and PE2 both learn routes from their respective CE1 and CE2
>> 
>> -          Those routes get passed onto our Route Reflector
>> 
>> -          PE2 knows routes in the VRF from PE1, and vice versa
>> 
>> -          Neither CE1 nor CE2 are learning any routes, other than connected ones
>> 
>> The customer is getting antsy, and from the documentation I can find, we should be set up correctly. Any help you guys can provide would be GREATLY appreciated! Now the details:
>> 
>> PE1=====RR======PE2

That command was put in by default, and when we try to remove it, we get this error "EIGRP is restricted to stub configurations only." It looks like this may be related to bug CSCeh58135. Unfortunately, I have very little experience with EIGRP. Do you think that's the likely source of the problem?
