Re: Just how important is route summarization in typical [7:14629]
I thought somebody was going to talk about masking instabilities. But then that begs the question - in a typical enterprise network (therefore a small one of 100 routes or less), if you are suffering from routing instabilities, isn't your time better spent to try to figure out why your routes are so unstable and then remedying it rather than engaging in summarization in order to mask the instability. But the summarization localizes the instability and speeds the time to find the links that are flapping. If I cut myself, and the wound stops bleeding, I am still likely to put a dressing on it to keep it clean. A large percent of the time, if the wound was clean to begin with, it won't get infected whether I put the dressing on or not. There are certainly differences in local practice -- American medical personnel wipe an injection site with alcohol first, while Europeans generally don't -- and, for routine injections (i.e., not, say arterial or IV), there's no noticeable difference in infection rate. Summarization is what the IETF calls best current practice, because experience shows that it tends to avoid problems. One of the most important reasons is that it forces, if you will, infection controls onto your addressing plan. Hierarchical networks are much easier to expand if your network suddenly grows, which it may in a world of mergers and acquisitions. I always wear my seat belt. Oh...and as long as we're mentioning grails, I'm off to the IETF in London. Perhaps I should request that I be addressed as Arthur, King of the Britons, and that I am on a quest. Like I said previously, I completely agree that summarization is indeed very useful in large networks like NSP/ISP's or large enterprises (1000+ routes), for many reasons (better lookup performance, masking truly becomes useful because you can't be expected to fix all your flaky links in a huge network, etc.). But I would like to understand if summarization can be useful in a typical enterprise network ( wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Performance gains are only a small part of the picture... what is more important is enforcing a proper hierarchical addressing scheme that conceals routing instabilities from the network as a whole, and lessens the amount of routing update traffic propagated across the entire network. It's gotten to the point that Cisco-trained personnel treat summarization like the holy grail, and they go around trying to use summarization techniques wherever they can. A network always benefits from the consistent application of design goals. Summarization scales well because of the architecture which flows from a properly addressed network. I can't think of anyone outside of an SP network concerned with global routing table bloat that ever equates the benefits of summarization in terms of increased routing table lookup efficiency. The benefit is that flapping routes and their attendant update traffic are confined to a small manageable area. Not only does this preserve bw but it greatly aids in network management by narrowing the scope of the network that you need to troubleshoot. So, when I weigh the cons of suboptimal routing as well as the possibility of misconfiguration, I find it difficult to see why the typical enterprise would ever really want to do summarization, as the gains are miniscule at best. If the network architects can't properly summarize, there are bound to be bigger problems than what that particular misconfiguration will bring.

There is no question begged. You make it sound like summarization is being used as a method to deal with a crisis. It is most emphatically not that. It is a network design principle/technique that can (among other things) reduce the impact of routing instability and isolate it so that you can deal with it effectively and quickly. Routing instability can be caused by hardware failure, not just configuration problems. No one goes around summarizing routes in the middle of an outage. Summarization is considered while designing and implementing the topology you have decided upon. Sound network designs should make sense, not just merely work because you can throw CPU/memory at them. Hierarchy simplifies understanding the network topology and actually aids in the sensible deployment of address space. What you are advocating is merely sloppy thinking that is excused only by its small scale: Close enough for government work. What happens if that enterprise succeeds and grows into a multinational with its own AS and countless branch offices.

Just how important is route summarization in typical enterprise [7:14628]
I agree that route summarisation may not speed up route lookup much. But there's other far more valid reasons for doing it. The network I work with is not ISP size in terms of routes, but it's pretty big, with hundreds of geographically dispersed sites - without summarisation, we'd have thousands of routes. Here's some reasons why we summarise... mostly they would apply to smaller networks as well. If you summarise (sensibly), you can hide route flaps from a large part of the network. If an ethernet segment in Bourke falls over, the router in Broome really shouldn't have to care less. By summarising, you restrict the number of routers that have to recalculate routes, so routers spend less time thinking about how to route and more time forwarding packets (hopefully). If you summarise (sensibly), you can reduce the amount of route information in your routing tables. Forget routing lookup time - depending on your routing protocol, this can substantially reduce the amount of data that has to be transferred between routers (less overhead traffic), and reduce the amount of calculations the router has to do. Again - less time doing (and sending) background stuff, more time to route real data. If you summarise (sensibly), it's much easier to read the ip routing table - fewer pages of info to wade through :-) I tweaked the summarisation of our network several months ago. Previously, we had been having occasional problems that were usually being put down to OSPF recalculations (mostly erroneously, IMO, but it was creaking occasionally). Since summarisation was beefed up, there have been no problems (or maybe people just decided they couldn't point the finger at OSPF any more :-) JMcL -- Forwarded by Jenny Mcleod/NSO/CSDA on 02/08/2001 04:48 pm --- nrf @groupstudy.com on 02/08/2001 02:42:45 pm Please respond to nrf Sent by: [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: Just how important is route summarization in typical enterprise [7:14601] Hey all. I'm going to risk starting a flame war by asking the following: I've been struck by just how much importance Cisco courseware places on route summarization. For example, every student who goes through CCNP-level courseware learns about all the various kinds of summarization - OSPF area summarization, OSPF stubs, EIGRP summarization, etc. etc., and how it reduces the size of the route table, thereby improving router performance by speeding route lookup. It's gotten to the point that Cisco-trained personnel treat summarization like the holy grail, and they go around trying to use summarization techniques wherever they can. Yet, I seem to recall somebody wrote a book (I believe it was Berkowitz) that basically stated that the performance gains associated with reducing the route table via summarization is virtually nil in typical corporate networks, because the real delays were caused simply by the serialization time of sending packets over slow WAN links (T-1 and slower). Plus, with fast-switching and its cousins (optimum switching, MLS, etc.), route lookup isn't done all that often , so there is little lookup delay anyway.And besides, most corporate networks aren't very big - typically less than 100 route entries, so how much lookup delay could there be? So, when I weigh the cons of suboptimal routing as well as the possibility of misconfiguration, I find it difficult to see why the typical enterprise would ever really want to do summarization, as the gains are miniscule at best. Note, I know full well that ISP's/NSP's and very large enterprises (those having on the order of thousands of routes) do indeed benefit substantially from summarization. Of this I have no doubt. What I cannot see is why the typical enterprise would really want to use summarization techniques. Anybody have any thoughts on this?

Re: Just how important is route summarization in typical [7:14632]
Hey all. I'm going to risk starting a flame war by asking the following: A bit more precision. You have to consider more than one kind of performance. One is route lookup in the fast forwarding path, and the other is changing the routing table (possibly in the same processor that does forwarding, in a small network). With modern algorithms such as Cisco's patented trie or the Patricia trie, route lookup times do not increase appreciably with the number of routes. Memory increases, but lookup time much less so. The increases in load come from changes to the routing table and consequent changes to the FIB.

Can anybody get PIX Ripv2 authentication to work? [7:14699]
Hey all: Got a PIX running 6.0 here, and I'm running Rip v2. Everything is working cool, I am passing Ripv2 updates between the PIX and my routers. But I cannot use any authentication. No matter how many ways I do the authentication, the Pix and the routers will not pass authenticated updates. I do debug, and I keep getting complaints about how the authentication is bad, etc. Note, I can get the various routers to authenticate to each other just fine. The part that is broken is the authentication from router to PIX. I have checked about 1000 times that the keystring is the same, and the same authentication mode is being used, so I'm sure that part is OK. So, has anybody ever gotten this to work?

EIGRP's interpretation of NBMA and disabling multicasting? [7:14693]
On Cisco's site, I've been searching for information as to when the hello interval is set to 5 seconds and when it is set to 60 seconds. Hellos are sent every 5 seconds except on low-speed, NBMA media. Low-speed is defined as 1.544 Mbps and under. No problems there. What I don't understand is this statement: Note that for the purposes of EIGRP, Frame Relay and Switched Multimegabit Data Service (SMDS) networks may or may not be considered to be NBMA. These networks are considered NBMA if the interface has not been configured to use physical multicasting; otherwise they are not considered NBMA. How can you configure an interface not to use multicasting? This is something I haven't come across how to do yet. Is this configuring EIGRP multicasts to use unicasts (I think I saw something like that last night but I was too tired to comprehend it or even remember where I saw it). -- Leigh Anne Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=14693t=14693 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
