What Is InterVLAN? We define inter-VLAN routing as a process of forwarding network traffic from one VLAN to another VLAN using a router or layer 3 device. A VLAN is a sub-group within a network, which partitions and isolates network traffic at the data link layer (Layer 2) of the OSI model. VLANs are used to segment networks for… Read More »
What is IP Address Route Summary? IP Address route summation; which is also known as route aggregation, is the process routers use in advertising volume or set of IP addresses as a single address with a shorter subnet mask (CIDR). Route summarization allows engineers to configure a routing protocol so that it advertises one route, replacing several smaller… Read More »
