I have an ASA adjacent to a router with the following redistribution into the EIGRP AS shared with the Cisco ASA:<br />

<br />
When I look on the ASA route table it's showing an AD of 170 and a metric of 25856 for the routes in EIGRP 10 that were redistributed from EIGRP 100. <br />
<br />
EIGRP Metric = 256 * ( (K1*Bw) + ( (K2*Bw) / (256-Load) ) + (K3*Delay) ) * (K5 / (Reliability + K4) ) ) &nbsp; &nbsp;{I'm assuming default K values 1 0 1 0 0 }<br />
<br />
256*((1*100,000)+((0*bw/25<wbr />6-load))+(<wbr />1*0) &nbsp; * &nbsp; &nbsp;(0/255+0) =&gt; 25,600,000<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;K`1*BW &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;K2*Bw &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;K3*dely &nbsp; &nbsp;K5/Rel+K4<br />
<br />
Anyhow the ASA is seeing traffic taking this route as 25856. I can not figure out where that number is coming from. The actual bandwidth between the ASA and router is 1Gbps. <br />
<br />
Any insight appreciated!

Calculating EIGRP Metric

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Cisco

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
