Example-1: Dual Router High Availability for a Branch with Redundant Service VPNs

A financial services company deploys two edge routers at each large branch to remove the router as a single point of failure. Corporate traffic (VPN 10) and guest/partner traffic (VPN 20) must both survive the loss of either router, and traffic should keep using the shortest path across the pair instead of hair-pinning through the peer router.

The dual_router_ha_features configuration below groups the two service VPNs into two redundancy groups. Group 1 carries the corporate LAN VPN and is tagged primary-router, so the first router of the pair owns it under normal conditions. Group 2 carries the guest LAN VPN and is tagged secondary-router, so the second router owns it. If a router fails, its groups are taken over by the peer. enable_optimize_paths is set to true so that the pair advertises optimized paths and avoids unnecessary inter-router forwarding.
