In the current setup, IntraNought nodes still rely on a static default gateway (172.27.27.1), which leads to inconsistent and asymmetric routing. For example, traffic from Windriver correctly reaches IntraNought nodes through the GRE tunnel and the active router. However, the return traffic does not follow the same path: it is sent to the static gateway (172.27.27.1), which corresponds to a different router (e.g. router-001, a non-active router). Additionally, the tunnel between Windriver and router-001 is no longer used. Windriver prefers the more specific /27 route via gre1 over the broader /24 route via gre0, so traffic is routed through the active router instead, as it should. So we need to ensure that: - IntraNought nodes receive the default route from the active router - default gateway (172.27.27.1) should be replaced - traffic always follows the active router - failover (CARP) is properly reflected in routing
