A network engineer is connecting an on-premises Cisco IOS XE router to a Cisco IOS XE router hosted in Google Cloud using two IPsec VTI tunnels. The on-premises router learns two equal-cost eBGP paths (one per tunnel) to the cloud VPC prefixes, but only one path is installed in the routing table, so the second tunnel carries no traffic. The engineer wants both tunnels to actively load-share the on-premises-to-cloud traffic. Which configuration change on the on-premises IOS XE router achieves this?
