Route ID: Set Router ID of the NGAF device.

Route Priority: Set the route priority of the NGAF device.

Timers: set the Heartbeat Interval and KeepAlive for the NGAF device.

Route Redistribution: Select whether to introduce the direct route, static route, OSPF route and RIP route into the BGP route as external route information and set the metric value after such routes are introduced.

Redistribute Direct Route: Select whether to introduce direct routes into the BGP route as external route information and Set the metric value after such routes are introduced.

Redistribute Static Route: Select whether to introduce static routes into the BGP route as external route information and set the metric value after such routes are introduced.
