Hi,
there is no "bit" in RIP to avoid loops. you would have to filter routes with distribution lists and also possibly adjust administrative distance.
In EIGRP there is a possibility to use SOO and BGP cost community to avoid loops. Have a look at "EIGRP MPLS VPN PE-CE Site of Origin (SoO)"
http://www.cisco.com/en/US/products/sw/iosswrel/ps1829/products_feature_guide09186a00806994d0.html
and at "BGP Cost Community Support for EIGRP MPLS VPN PE-CE with Backdoor Links"
http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_guide09186a00805ad31e.html
for the technical details and configuration examples.
Hope this helps!
Regards, Martin
