In the context of this document, BGP Route Reflector (RR) is the component of the SDWAN Controller that receives the BGP UPDATE from SDWAN edges and in turns propagates the information to the intended peers that are authorized to communicate via the SDWAN overlay @@ -37,21 +37,21 @@ Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time.
