You can configure descriptions for static Route on Cisco Router with the name keyword in the ip route command. Find ip route command options with help on Cisco Router. Router(config)# ip route 192.168.1.0 255.255.255.0 172.16.2.2 ? <1-255> Distance metric for this route name Specify name of the next hop permanent permanent route tag Set tag for this route track Install route depending on tracked item <cr> The following example shows that using the name <next-hop-name> keyword and argument combination for each static route in the configuration helps you remember the purpose for each static route. Router(config)# ip route 184.108.40.206 255.0.0.0 10.0.0.1 name Hyd2Pune Description on Static Route is an optional command and But it’s very simple and quite useful. It is very useful in easy understanding and troubleshooting purpose. For more command reference for IOS release 12.2.
What is Administrative Distance? Administrative distance is the feature that all Routers use to select the best path when there are two or more different routes to the same destination from two or more different Routing protocols like RIP, EIGRP or OSPF etc. Administrative distance is a measure of the trustworthiness of the source of the Routing information. Administrative distance is the first criterion that a Router uses to determine which routing protocol to use if two protocols provide route information for the same destination. Administrative distance has only local significance and is not advertised in any routing updates. Administrative Distance list of All Routing Protocols: Cisco Routers supports many static and dynamic Routing protocols for learning routes in a complex network topology. The Cisco Routers supported the following Routing protocols. Static RIP OSPF BGP IS-IS IGRP EIGRP Each Routing protocol has its own Administrative Distance (AD), which is a […]
Comparision and Difference between all Dynamic IP Routing Protocols In this post I covered the comparison between all IGP dynamic IP Routing protocols like RIPv1, RIPv2, OSPF and EIGRP with all important specifications. RIP Version 1 RIP Version 2 OSPF EIGRP Name Routing Information Protocol Routing Information Protocol – v2 Open Shortest Path First Enhanced Exterior Gateway Routing Protocol Type Distance Vector Distance Vector Link State Hybrid Protocol Open Standard Open Standard Open Standard Cisco Proprietary Metric Hop Count Hop Count Cost Composite – BW & Delay Maximum Hop Count Max Hop Count 15 Max Hop Count 15 Unlimited 255 AD 120 120 110 90 – internal170 – External Update Timer Every 30 Sec Every 30 Sec Triggered Triggered Update Type Broadcast (255.255.255.255) Multicast (220.127.116.11) Multicast (18.104.22.168/6) Multicast (22.214.171.124) Scalability Not Scalable Not Scalable Scalable Scalable Authentication No Yes Yes Yes Load Balancing Equal Equal Equal Equal and Unequal Convergence […]
This post describes the most important characteristics of various Dynamic Routing Protocols that are used in Cisco IOS routers. Characteristics of dynamic IP Routing Protocols RIPv1 Distance Vector Protocol. Suitable for small to medium networks (Supports maximum hop count of 15). Metric for best path is Hop count Slow convergence speed. Supports Classful Routing(Don’t Supports CIDR and VLSM) Open Standard protocol, supports multi-vendor networks Updates with Broadcast IP 255.255.255.255 Timers: Hello Time 30sec, Hold Time 180sec & Flush Time 240sec Administrative distance: 120. Don’t support Authentication. Bellman-Ford algorithm is used to determine the shortest path.
What is Routing? Routing is a process of finding the available paths (also called Routes) to reach a particular destination, It will maintain a table with a best path or Route out of all available paths or routes to a particular destination is called Routing table, Routing is usually performed by a dedicated device called a Router. Routing specifies how the routers communicate, disseminating the information which enables the routers to be selected between two nodes in a network. Routing protocol interacts and informs the hardware that is needed to transmit the data between transmitter and the receiver for transmission over network. Types of Routing There are three basic methods to build a routing table on any Networking Device. 1. Static Routing 2. Dynamic Routing 3. Default Routing Static Routing: A static routing occurs when you manually add routes in each Router’s Routing table, Routing table should create, maintain, and update by a network […]
