SCENARIO
The branch router has lost connectivity to the 10.40.0.0/16 HQ network. Both WAN links and all interface addresses are already correct. ISP-A must remain the preferred path, while ISP-B should take over only when the primary route disappears.
TASK
Repair branch-router.cfg so 10.40.0.0/16 uses ISP-A next hop 198.51.100.1 at administrative distance 1, with ISP-B next hop 203.0.113.1 as backup at distance 200. Preserve the hostname, interface addresses, descriptions, and enabled state.
