OSPF (Open Shortest Path First) is widely used in large enterprise networks. It supports both IPv4 and IPv6 and is a link-state routing protocol that provides fast convergence and scalability.
A default route is used to direct packets to a gateway router when there is no specific route for the destination IP address in the routing table.
The route print command displays the routing table on a Windows server, showing the network routes the system uses to determine how to reach different network destinations.
User Defined Routes (UDRs) in Azure allow administrators to create custom routes that override Azure's default routing to direct traffic to specific network appliances or gateways.
AS (Autonomous System) numbers are used in BGP to identify and differentiate between distinct routing domains or networks. They are essential for establishing BGP sessions and exchanging routing information between different networks.
