Explanation

HA VPN throughput and redundancy requirements: Each HA VPN gateway can support a maximum of 3 Gbps of throughput per gateway with two tunnels in active/active mode. Since your requirement is approximately 4 Gbps of bandwidth and 300,000 PPS, one HA VPN gateway would not suffice. Using two HA VPN gateways ensures sufficient capacity to handle the required throughput. To achieve a 99.99% SLA, you need to configure HA VPN with two tunnels per gateway in active/active mode (equal routing priority). This ensures redundancy, load distribution, and high BGP configuration for load balancing: - By configuring the base routing priority metric (100) equally on both tunnels of each gateway, you ensure that traffic is evenly distributed across all tunnels. - On the on-premises router, configure the same multi-exit discriminator (MED) values for all tunnels to maintain consistent routing behavior.
