  • Connecting OSPF Areas without Virtual Links

    To connect two OSPF regular areas without a virtual link, you can use a GRE (Generic Routing Encapsulation) tunnel. Here’s a step-by-step guide: Why GRE Tunnel? A GRE tunnel allows you to encapsulate OSPF packets within a GRE header, which can be routed through a non-OSPF area. This approach eliminates the need for a virtual

  • 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

  • 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
