This feature provides enhanced routing with its support for multiple default gateways.
Each IP network interface (whether it’s Control, Media, or OAMP) can now be defined
with a default gateway. This is configured in the existing Multiple Interface table
(InterfaceTable parameter).
6. Static Routing Table Enhancements:

The device’s IP Routing table (StaticRouteTable parameter) has been enhanced to
provide offline configuration of IP routing rules. The rules in this table can now be
associated with an IP interface defined in the Multiple Interface table (rather than the
previously used index). Therefore, the routing decision is now based on the source
subnet/VLAN. In the previous release, the routing decision was based on the
destination IP address only and therefore, for example, packets from the Media subnet
could be routed to the Control subnet and vice versa. This enhanced routing behavior
prevents cases where static routes are lost and simplifies the static routes
configuration for Control and Media subnets.
In addition, a new table column has been added to provide the current status of a
configured route (“Active” or “Inactive”). After adding a new route, the device attempts
to apply the route. If the operation fails, the route is marked as “Inactive” until it can
become active (following a change in the routing/interface tables).
