What is the most likely cause of this problem?

Your on-premises data center has 2 routers connected to your Google Cloud environment through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.

During troubleshooting you find:

• Each on-premises router is configured with a unique ASN.

• Each on-premises router is configured with the same routes and priorities.

• Both on-premises routers are configured with a VPN connected to a single Cloud Router.

• BGP sessions are established between both on-premises routers and the Cloud Router.

• Only 1 of the on-premises router’s routes are being added to the routing table.

What is the most likely cause of this problem?
A . The on-premises routers are configured with the same routes.
B . A firewall is blocking the traffic across the second VPN connection.
C . You do not have a load balancer to load-balance the network traffic.
D . The ASNs being used on the on-premises routers are different.
