Routing Information Protocol Version 2 – RIPv2. RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. As with other classless routing protocols, RIPv2 supports CIDR supernets, VLSM and discontiguous networks. Due to the deficiencies of RIPv1, RIP version 2 (RIPv2) was developed in… Read More »
What Is Multi-Area OSPFv3? Before we look at Multi-area OSPF, you must understand OSPF single-area concepts and configuration. OSPF (Open Shortest Path First) is a classless (supports VLSM and CIDR.), Link State Routing Protocol with an Administrative distance (AD) of 110. OSPF is more efficient than distant vector routing protocols, any routing changes trigger OSPF routing updates which are propagated… Read More »
What Is CIDR? CIDR (Classless Inter-Domain Routing) was introduced in 1993 (RCF 1517) replacing the previous generation of IP address syntax – classful networks. CIDR allowed for more efficient use of IPv4 address space and prefix aggregation, known as route summarization or supernetting. CIDR introduction allowed for: CIDR allows routers to group routes to reduce the bulk of… Read More »
