Topological experiment of typical architecture diagram of ISIS-BGP-VRRP metropolitan area Network

Requirements: Suppose the AS65001 network is a telecommunication network AS65002 Network is a mobile network, the network segment 202.106.15.0 is the telecommunication service segment, the network 202.106.48.0 is the mobile service segment

Mutual access, and R4 can remotely control R1.
