Each VPN includes IP addresses that are unique within that VPN. This can lead to VPN discovery issues when identical IP addresses overlap on the access interfaces between the VPN Provider Edge devices (PE) and the Customer Edge devices (CE).
Each VPN includes a single routeTargetId that uniquely identifies it. Routing within VPNs is managed by Virtual Routing and Forwarding tables (VRF) that track each routeTargetId within the network. PE devices, such as routers, use VRF tables to establish Layer 3 VPN paths through the MPLS network.
The Adapter appends the VPN routeTargetId to the configured name of each IP address within a VPN, uniquely identifying each IP address. The new identifier is in the following format:
