Do you use the highest, lowest or average value for the entire route? Load and reliability are cumulative as far as I can tell. That is, they reflect the load and reliability for the entire path. That's what Doyle says and I now believe him. :-) You can test it without even messing with the K values. To see the reported load and reliability, use a protcol anzlyer, or, even easier: do a show ip route with the network of choice as a parameter. The info is shared and saved even, if it's not used to calculate the composite metric. Also if anyone could point me to a document on the above it would be appreciated. Many thanks in advance. I did some testing. It was impossible to come up with a testing methodology that would give a conclusive result, especially considering the limitations of my lab, and the limitations of the protcols, but I'm pretty sure that both load and reliability are cumulative. Well, for reliabiity, the error rate is cummulative really. And load does seem to be somewhat smart about different bandwidths. It can't be too smart since it only knows the lowest bandwdith for the path, but it seems to take this into account along with the bandwidth for its interfaces, which is necessary for a cumulative load to mean anything. Needless, to say, the real answer is don't even bother with reliabilty and load as IGRP or EIGRP metrics. With a 90-second update timer (IGRP) and nonperiodic, partial, and bounded updates for EIGRP, the protocol can't possibly keep accurate track of the sampling that interfaces do every 5 seconds to determine the load and reliability. It's kind of weird that Cisco let these two opposing goals end up in the protocol: * Low bandwidth usage by the protocol (infrequent updates) * Path selection based on quickly-changing load and reliabity metrics Well, probably nobody cares (and rightly so! ;-) But it was bothering me that the original poster never got a good answer. Priscilla Remember this oldie but goodie question? Most of the answers were links to papers that don't answer the question. I answered the question by saying that load is the highest load on any segment in the path and that reliability is the worst reliability on any segment in the path. However, I noticed that Doyle says that load and reliability are cummulative. For reliability, he says: Reliability reflects total outgoing error rates of the interfaces along the route. For load, he says: Load reflects the total outgoing load of the interfaces along the route. So, if Doyle is right, I guess we can assume that a router accepts a route from a downstream neighbor, looks at reliability (expressed as a fraction of 255) in the route, looks at the reliability on the incoming interface (also expressed as a fraction of 255), and somehow munges those together to form a reliability figure that it should pass on to its upstream neighbors for that route. Would it multiply the values?? Assuming a router actually cares about this part of the composite metric, the inverse of this reliabilty result gets folded into the metrc. (I say inverse because metric is cost and we care about the error rate not the reliability). For load, if Doyle is right, we can assume that a router accepts a route from a downstream neighbor, looks at load (expressed as a fraction of 255), looks at load for the incoming interface (also expressed as a fraction of 255), and somehow munges those together to form a load figure that it should pass to its upstream neighbors. Does it add them?? Wouldn't that be adding apples and oranges? 255/255 load on a T1 is different from 255/255 load on Fast Ethernet. Of course, the router does have the bandwidth for the route too, so it could use that for calculating a cummulative load too. So, I think my answer makes life much easier for the routers. Just report whichever is worse, the one in the incoming route or the one for your incoming interface. The result is that the load for a route reflects the highest load of any segment and the reliability reflects the worst reliability for any segment. It's not quite as granular, but I think it would be fine as a metric. I really did think it worked that way, though I can't find any documentation that says this. But I think a Cisco person told me this. So I tried to do some testing, but of course, load and reliability are so variable, and IGRP and EIGRP are so not variable, that I didn't have much luck determining the truth. Plus I managed to put routes in holddown by increasing the load too much! With IGRP updates only being sent every 90 seconds, they obviously don't take into account real-time load and reliability anyway. And with EIGRP

With IGRP updates only being sent every 90 seconds, they obviously don't take into account real-time load and reliability anyway. And with EIGRP, there are no updates unless there are changes. So the inclusion of load and reliability are silly, but I still wonder what they mean if they are used. If I had enough sniffers I could have tested IGRP. A 90-second update timer isn't too painful. Even without the metric weights command, the info is passed in the updates. I would need a couple sniffers to see how the values change compared to the router interface values. By the way, even when reliability and load aren't used in the composite, you can still see their value for a route in the routing table if you do show ip route . So testing my theory is possible, but not practical in my limited lab network. So, has anyone gotten this far in this long-winded message? :-) Does anyone know how load and reliability are really calculated? Would anyone like to take on the project to test it? Is it the worst or cummulative? Please don't send me to a URL that doesn't really answer the question. The ones that cover the weighting (K values) don't answer the question. The one that talks about FTP and the question of how often load is calculated also doesn't answer the question of whether load is cummulative or the worst case when calculating the metric for a route. Thanks for listening and thanks in advance for anyone who would like to help me unravel the mystery!? (Or should we just believe Doyle! That usually works!)

Re: Unexpected behavior of IGRP and EIGRP [7:64625]
i can't figure out why u r using IGRP in R3, since obviously he would know about the routes. Regards, Amar. I was testing auto-summary with different protocols and I ended up in this configuration, before remove one of the protocols. actually it is Eigrp that has a better AD than Igrp, 90 and 100, respectively, the route u see in ur table has 170 as the AD, therefore External EIGRP,caused by the implicit redistribution, imposed when using these routing protocols with the same AS. If I got that right, even if the value used in the routing table (170) is higher than the route from IGRP (100), the process will consider the route better because it is from EIGRP (90). It makes me wonder how the value 170 is applyed to the route (I know it is not sent by R2, or is it, indirectly?).

Re: IGRP over EIGRP...How?? [7:33760]
Mike/cisconuts That's true on the longest match wins, but that's not the exact issue here. The problem is that IGRP is classful and EIGRP is classless. So essentially IGRP will install the classful route of 6/8 and EIGRP will install the route of 6.6.6.6/32 into the routing table.

Variance in IGRP and EIGRP [7:9754]
I am working with a lab setup and have a question on variance. I know what the variance does, but it does not work with all routes. I have the variance set to the maximum on all routers (128), but only certain unequal routes get placed in the routing table. If I shut down the link on one of the routers the higher metric routes get installed, but only in the event of a link failure. I know there are some rules that govern the installation of a route once the variance is configured, if someone has a concise explanation of what they are and how they work it would be greatly appreciated. Thanks in advance.

Variance in IGRP and EIGRP [7:9756]
Please disregard my earlier question, I found the answer. Apparently for a route to be installed for unequal cost load balancing the routes metric must still be lower that the routers feasible distance to the destination, and that is why I am only seeing the routes in the event of a link failure.

Re: Variance in IGRP and EIGRP [7:9754]
From BSCN Guide: Only paths that are feasible can be used for the load balance and included in the routing table. Feasible conditions are: 1) Local best metric Best metric learned from the next router. 2) The multiplier x Local best metric for the destination Metric through the next router. If both conditions are met, the route is called feasible and can be added to the routing table. Hope this helps!

Re: IGRP to EIGRP conversion #2
Timothy - I think that you've asked this a few times but never with this type of information. Let's get things a bit more organized with all due respect. I really would like to help you as migrations to EIGRP can be tricky. First, what are the models and memory installations of the routers? Second, what are the remote links and their utilizations? Third, are the remotes all stubs - just an Ethernet on the other side? Is the frame-relay configuration point to point or multipoint? I ask because EIGRP usually does not do well in hub-and-spoke designs. This is due to the number of neighbor relationships that are established. With five neighbors and solid routers you might be fine, but growth would be a concern. Since you are running F/R you might want to consider ODR, which would take no additional bandwidth. You might also want to look at RIP v2. EIGRP is really good for larger, more complex networks. Its usually overkill for smaller hub/spokes, which usually are in processor/memory challenged networks. I look forward to hearing from you. --- "Roberts, Timothy" [EMAIL PROTECTED] wrote: I have a hub site with 5 remote sites connecting to it via frame relay. They are all running IGRP with the same AS.

Re: Converting from IGRP to EIGRP
Cisco provides a feature called automatic redistribution (or something like that). If you make the process ID/AS number for EIGRP the same as IGRP on the router it will automatically redistribute in both directions. This is a bad idea for all but the simplest networks. In the best redistributions a designer wants to prevent a route from coming back and looping (AD and metric should normally prevent this, but it helps to know your network). Also, summarization and manual control of the routes is prefered for EIGRP under most circumstances. Lastly, why lose control over somehting that is so simple - automatation indicates that the administrator does not understand the requirements, which would usually complicate troubleshooting. --- Santosh Koshy [EMAIL PROTECTED] wrote: First, please do not put everything in the same AS.

Re: Converting from IGRP to EIGRP
First, please do not put everything in the same AS. This is a very bad thing, and I really wish Cisco would kill the feature. (I think it was placed in there for marketing) There are two standard ways to do this. The first is border - you simply redistribute and filter with distribute lists. The redistribution point can be moved as you convert, or more added (although you should only have two routers invloved if possible). The other is overlay. Both IGRP and EIGRP run on all routers in the network, but EIGRP's AD is weighted higher. Then you pull IGRP off. Any router that is not running IGRP will advertise the routes via EIGRP, and the only real trick is memory and making sure that you work from the outside in on the IGRP removal. --- "Roberts, Timothy" [EMAIL PROTECTED] wrote: I posted this a few weeks ago and only got a few responses so I thought that I would try again.

Re: Converting from IGRP to EIGRP
Having just recently done a migration from IGRP to EIGRP in a hub and spoke network, I learned a few basic guidelines for the migration. #1. Have a plan! I cannot tell you how many times I came across engineers just wanting to just flip the switch and enable EIGRP without any pre-planning. It is imperative that one understands the need for good subnetting and summarization. Also, it is critical, that in the event of a failure during the migration plan, you also have a back out plan. #2. Do one location at a time. When you make a change, minimize variables. Now, this step can be open for argument and it truly depends on your network topology and your plan. The reason I bring it up is because it proved useful in my hub and spoke network migration. What I did for each location was to run IGRP and EIGRP with the same process number on the hub. When I migrated a site, I enabled EIGRP, and verified the EIGRP routes were propagating. Once verified, I disabled IGRP on the remote router and on the hub side, under IGRP, I specified a passive interface for that point-to-point sub-interface. It works well in my case because if a problem arose, I could pin it down to one or the other routing protocol. #3. After making changes, monitor for a decent period of time to determine if everything went smoothly. For my changes, I picked 3 days. I had international sites, so I needed to see data patterns across time zones. #4. Document the hell out of what you did. #5. Bonus! In my research, I also discovered that in the newer versions of IOS, there is such thing as a "stub" network in terms of EIGRP. It allows for maximum stability in a hub and spoke network. There is a great page on CCO that describes it well: http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/12 0limit/120s/120s15/eigrpstb.htm#16026 watch the line wrap Anyway, I hope my own experience can add to yours! -Joseph -- From: "Santosh Koshy" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Newsgroups: groupstudy.cisco Subject: Re: Converting from IGRP to EIGRP Date: Wed, Feb 14, 2001, 5:42 PM First, please do not put everything in the same AS.

Re: IGRP to EIGRP
You have two choices for all intents and purposes. The first is divide and attack. Pick a redistribution point and move that point through the migration. This is a great method if you are building new services at the same time. The second is overlay. We are doing this now, and it works, but its a bit more complex to backout and manage during migration. Effectively you place EIGRP on all routers with a higher AD. IGRP is the protocol in use due to the AD. Usually EIGRP will have summaries which will not be used but will be in the table. When ready start pulling IGRP off the routers - everything is running EIGRP, so the routes will be there. Don't ever use the 'automatic' redistribution that Cisco provides, always use 'no auto-summary' and take a look at Pepelnjak's book.
