Traffic Engineering in EIGRP using Delay
Here i am going to explain how to change paths using delay in EIGRP, We already know that EIGRP uses Bandwidth and Delay for metric calculation but we cant change bandwidth of links in production network . The path with lesser delay will be the desired path. In the above topology there are two

Update Tuning in RIPv2
In RIPv2 we can tune its updates there are so many ways , Lets see some of them RIPv2 Broadcast updates Normally RIPv2 uses 224.0.0.9 as the multicast address but we can change it to global broadcast address. debug ip rip of R1 is given below *Sep 25 14:38:38.069: RIP: sending v2 update to 224.0.0.9

Rapid Ring Protection Protocol (RRPP) STP alternative from HP Networking
RRPP is a protocol designed for the HP switch as a ring architecture. This article only describes the setting of a single ring. The concept is to set a switch as the main node in the ring architecture, and the rest switches as transmitting nodes. Each switch A primary port and a secondary port will

Route Manipulation in RIPv2 using AD Value
In this article i am going to explain how to manipulate route with AD value in RIP. For this i am using the same old topology. 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks R 10.4.4.0/24 [120/2] via 172.16.23.1, 00:00:19, Serial1/1 [120/2] via

Route manipulation in RIPv2 using Offset-List
In this topology we are using RIPv2 and R2 is getting route information about 10.4.4.0/24 from R3 and R1. But i don’t want to install two routes in the table. I want to use R3 to reach that network for that i am using Offset-List. Lets check the present routing table of R2 10.0.0.0/8 is

Why did it choose this path ?
Lets check path selection in routing , Find the longest match:- We want to go to 1.2.3.4 and in the routing table there are three entries like 1.0.0.0/8 is variably subnetted, 3 subnets, 3 masks S 1.0.0.0/8 [1/0] via 172.16.12.1 S 1.2.0.0/16 [1/0] via 172.16.12.2 S 1.2.3.0/24 [1/0] via 172.16.12.3 Then it will choose 1.2.3.0/24

What is permanent key word in Static Routing ?
In the Static routing there is one key word permanent is there, lets check the significance of that. If the exit interface is Down then the route will also removed from the table so in some cases we want to keep the routes in the table even if the exit interface is down. For that

Static Routing in Cisco Router
Routing is the process of selecting paths for networks. We can use either Static or Dynamic method for this, in static routing the administrator itself assigning paths for each unknown networks but in the case of dynamic protocols are building paths for those unknown networks. There are some advantages and disadvantages for those two methods,
