In dynamic routing on FortiSwitch, certain types of interfaces are utilized to participate in the routing processes. The types of interfaces that can be used include:
Loopback Interfaces (B):
Loopback interfaces are virtual interfaces that are always up, making them ideal for use in routing protocols where a stable interface is necessary. They are commonly used to establish router IDs and manage routing information more reliably.
Switch Virtual Interfaces (C):
Switch Virtual Interfaces (SVIs) are assigned to VLANs and can have IP addresses assigned to them, making them capable of participating in Layer 3 routing. SVIs are essential for routing between different VLANs on a switch and can participate in dynamic routing protocols to advertise networks or make routing decisions.
Physical Interfaces (D) and Detected Management Interfaces (A) are not typically used directly by dynamic routing protocols for their operations in the context of FortiSwitch.
