MD5 Routing Protocol Authentication – Exclusive Explanation

Network security is an important consideration for network administrators. The router install in a public network is at risk each time, anyone with a packet sniffer can read information propagating between routers. The router can be attacked through the interruption of peer devices or the falsifying of routing information. Interruption of peers is less critical… Read more

How to Configure EIGRP Load Balancing for IPv4

By Asad Ijaz

EIGRP is a Cisco proprietary routing protocol. Router-enabled EIGRP calculates the best route to a destination using the metric value based on the link bandwidth and delay. The protocol selects the shortest path and installs that path in the routing table. If the destination has more than one path with the same administrative distance and

EIGRP Hello Protocol – Exclusive Explanation

By Asad Ijaz

Hello Intervals and Hold Times – EIGRP for IPv4 EIGRP uses the Hello protocol to establish and maintain a connection with its neighbor and monitor the established connection. It sends a Hello packet periodically to its neighbor. The rate at which EIGRP sends a Hello Packet is known as the Hello interval. The Hold timer

How to Configure EIGRP Bandwidth

By Asad Ijaz

EIGRP Bandwidth for IPv4 EIGRP utilizes 50 % of an interface’s bandwidth for EIGRP information by default. Utilizing a half interface bandwidth not allowing enough bandwidth for the routing of normal traffic and prevents the EIGRP process from over-utilizing a link. We can change to default bandwidth utilization ratio using the command “ip bandwidth-percent eigrp”.

How to Propagate the Default Static Route using EIGRP

By Asad Ijaz

The IP address 0.0.0.0/0 is reserved for the default static route. The default route is not routing protocol-dependent; we can use it with any currently supported routing protocol. Usually, the static default route is configured on the edge router, where a network is connected outside the EIGRP routing domain and propagates the default static route

How to Configure EIGRP Manual Summary Routes

By Asad Ijaz

We can configure manual summary routes without enabling the auto-summary. We can also use a manual summary if auto-summary is enabled because EIGRP is a classless routing protocol. Classless routing protocol includes the subnet mask in the routing update; therefore we can configure manual summarization using the supernet routes. In supernetting, we can aggregate multiple

How to EIGRP automatic summarization

By Asad Ijaz

Route summarization is the most common tuning method of EIGRP. It allows a router to group multiple networks and advertises them as one large group using a single, summarized route. The capability to summarize routes is very important due to the rapid growth of networks. Route summarization reduces the number of routes in a larger

Topology Table – Exclusive Introduction

By Asad Ijaz

The EIGRP topology table contains all of the information about all known routes received from EIGRP neighbors. As an EIGRP router learns routes from its neighbors, those routes are stored in its EIGRP topology table. If a neighbor is advertising a possible route, it has to be using that route to forward packets to the

Successor, Feasible Successor and Feasible Distance

By Asad Ijaz

Successor -A successor route is the best route to a destination network. EIGRP uses the successor route to forward traffic to a destination. This is the router which is stored in the routing table. A successor route is based on the advertised distance from the neighbor. A successor route is a least-cost route to the
