[c-nsp] MPLS InterAS Drafts/RFC

[Annu Roopa]

Hello Folks,
   
  Is there an Internet draft or RFC for MPLS Inter-AS VPNs. I know there 3-4 options with Cisco to configure but could not find any draft or RFC pertaining to this on Web.
   
  Could someone point me to these ? Are these Cisco proprietary solutions ?
   
  Thanks for your help.
Annu.
