Solution Application

The proposed solution incorporates Enterprise WAN Finance Architecture, which utilizes Ethernet Virtual Private Network (EVPN) technology to enable Active/Standby redundancy. This setup ensures high availability and resilience for critical financial data transmission. Additionally, the architecture implements Next Generation Multicast Virtual Private Network (NGMVPN) in the SPT-only mode to efficiently manage multicast traffic across Multi-Protocol Label Switching (MPLS) IP Virtual Private Network (VPN), utilizing Resource Reservation Protocol-Traffic Engineering (RSVP-TE) for optimized transport. To keep the design simple, PIM Sparse Mode is used with a Static RP.

In the underlying network topology, Open Shortest Path First (OSPF) is deployed as a routing protocol, facilitating dynamic routing capabilities among multiple nodes. Furthermore, Two-Way Active Measurement Protocol (TWAMP) is employed for SLA (Service Level Agreement) monitoring, enabling proactive performance assessment between access points and customer routers.

To enhance the traffic management, Class of Service (CoS) is configured with multifield classifiers that prioritizes multicast traffic with a strict-high priority designation, while assigning a lower priority to all remaining services.
