What is Routing

What is Routing : Processing of packets from one network to another network is known as routing.

Basic components needed to route:
? Routable Protocol (IPv4, IPv6, etc.)
? Network address with? Subnet mask
? Next Hop & Metric

Points to Remember

  • Router will only use routes with reachable ?next hops?
  • Routers will only use the ? best? routes
  • Routing protocols DO NOT send packets across the network. Their
    role is to determine the best path for routing. Routed protocols actually send the data, and the most common example of a routed protocol is IP.
  • The routing table is concerned with two types of Layer-3 protocols:
    ? Routed protocols – assigns logical addressing to devices, and routes
    packets between networks. Examples include IP and IPX.
    ? Routing protocols – dynamically builds the information in routing
    tables. Examples include RIP, EIGRP, and OSPF.

Types of Routes
? Connected
? Static
? Dynamic

Routing Updates

  • Incremental update > changes are sent in the routing update
  • Full update >? All of the routing table is sent in the update
  • Periodic update >? Sent in the specified time interval
  • Triggered update > Sent whenever change is detected

Administrative Distance (AD)
? Ad is? trustworthiness of a routing protocol
? 8-bit? and Ranges from 0 through 255

Types of Routing

  1. Static Routing
  2. Default Routing
  3. Dynamic Routing
