Abstract
The present invention relates to providing virtual private network (VPN) services between two or more Autonomic Systems (AS). An aggregation edge router (ASBR) is provided in two or more autonomous systems (Asx,Asy). The aggregation edge routers are configured such that routing peering between the two or more autonomous systems is done between the aggregation edge routers in these autonomous systems. Each aggregation edge router is a routing peer of other edge routers (PE) in its own autonomous system. The Multi-Protocol Label Switching (MPLS) network is used between the different autonomous systems.
