Cisco NetFlow

NetFlow is a network protocol designed by Cisco which is used for collecting IP traffic information and monitoring network flow. By analyzing NetFlow data, you can get a picture of network flow and volume. Traffic can be grouped and analyzed based on different criteria like interface, source IP, destination IP, IP protocol, source/destination TCP/UDP port and service type. Routers and switches that support NetFlow can collect IP traffic statistics as NetFlow records towards at least one NetFlow collector server that does the actual traffic analysis. Popular NetFlow Analyzer Software Popular NetFlow Analyzer Software Solutions are: SolarWinds NTA (NetFlow Traffic Read More …

OSPF (Open Shortest Path First)

What is OSPF? OSPF (Open Shortest Path First) is an open source dynamic routing protocol based on Link State Routing Algorithm for IP Networks. It has a Protocol Type/Class which is based on IP/Link-State. OSPF uses an Algorithm called SPF (Dijkstra) to determine the shortest path. It is an IGP (Interior Gateway Protocol) Type of protocol and it uses Cost (Bandwidth) as its metric value. OSPF has 5 no. of packet types and has an Admin Distance of 110. It has a Reference Bandwidth of 108 and has a defined Standard of IETF RFC2328 (OSPFv2), IETF RFC2740 (OSPFv3/IPv6) for OSPF Read More …

Static and Default Routing

Static and Default Routing are two types of routing in which the path selection is controlled manually by a network administrator. STATIC ROUTING “It is a type of fixed routing in which path selection and routing is controlled manually by a network admin”. Static routes have Admin Distance (AD) of 1. Path selection and routing is manually controlled by a network administrator in static routing. Static routes are always preferred over Dynamic routing protocols like OSPF/RIP/BGP. They consume less resources and less bandwidth intensive. Static Routes are not fault tolerant (paths are always fixed). Therefore, they are not practical for Read More …
