What is a floating static route?
Answer: A static route with a higher administrative distance used as a backup when the primary route fails
A floating static route has a higher administrative distance than the primary route so it only appears in the routing table when the primary route is removed.
What protocol does OSPF use at the IP layer for neighbor communication?
Answer: IP Protocol 89
OSPF uses IP Protocol number 89 for all communication including hello packets, LSAs, and database exchange between neighbors.
In the context of Aruba routing, what is a VLAN interface (SVI) used for?
Answer: To route traffic between VLANs at Layer 3 on a multilayer switch
A VLAN interface (Switch Virtual Interface) provides a Layer 3 IP address for a VLAN, enabling inter-VLAN routing on a multilayer switch.
What is the maximum valid hop count in RIPv2 before a route is considered unreachable?
Answer: 15
RIPv2 has a maximum valid hop count of 15; a metric of 16 means the destination is unreachable and the route is not installed.
Which routing concept prevents a router from sending routing updates back out the interface from which they were received?
Answer: Split horizon
Split horizon prevents routing loops by not advertising a route back out the same interface through which it was learned.
What is the purpose of a loopback interface in Aruba router configuration?
Answer: To provide a stable router ID and management endpoint that is always up
A loopback interface provides a stable, always-up IP address used as a router ID for protocols like OSPF and as a reliable management endpoint.
