Re: Cisco VS Foundry Networks.. [7:36448]
I've read a few of the responses to this question and haven't seen anyone mention the lack of debug support on Foundry equipment. Has Foundry added debug support yet ? If not, that alone is a compelling reason to buy from cisco. One of many reasons, but to me, debug is virtually mandatory in a real, production network.

Re: Why use wildcard mask [7:30473]
For some reason, this thread makes me think about the all zeros broadcast. And how glad I am that it's not used anymore. That would confuse the hell outta me. Wonder if Howard's explanation might be the reason why all zero's was done at one time. Oh well, just another item to think about. wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi All, I am trying to find out why we do an inverse/wildcard masks while using access lists? For example, if I want to deny 192.168.1.0 255.255.255.0 network, on the access list, we configure this as 192.168.1.0 0.0.0.255, but why do we do it this way instead of 255.255.255.0. All this seems to be is just an inverse relationship pointing back at the same thing? Even if I want to get specific and deny 192.168.1.0 255.255.255.192, this translates to 192.168.1.0 0.0.0.63, which seems to be just the standard mask and subtract 255.255.255.255. Is there a specific reason why we do inverse mask? It seems to be easier just to configure it with normal masks.

Re: RRs and Confeds as they relate to IE studies [7:29968]
Good question. I don't claim to be an expert on BGP and will not comment on the advantages and disadvantages of RR/Confeds in large/small environments. I've only config'ed BGP once in a prod net. Seems to me tho that there is an important distinction between the two as they might pertain to the lab test. Both allow the use of weight and local preference (IBGP). Confeds allow the use of MED since the connections between the confeds is EBGP. You could also config multiple RR's (clusters) to allow the use of the MED between the clusters but to me, confeds are easier. I'm sure that there are other reasons to use one or the other as they relate to the lab, but I haven't run into it yet. Maybe I'm wrong, but this is my take on RR's/confeds.

I have DSL with a lame Home Portal combo F/W, USB and Enet hub, can opener and toaster. I have permitted telnet thru this cheapo box. I'm using Exceed on my laptop. Problem is, when I telnet into my laptop, then try to open a telnet from there into my lab, the telnet window only opens up locally on the laptop (I.E - from his host all he will see is DOS prompt - my laptop will have telnet window opened). Tried messing with comspec in Exceed to run telnet.exe instead of command.com (found it to be a reliable way to lock up my laptop). I know I could set up X and export my display, but it's a lot of work and I'm a little leery of security (xhost + :( ) Anybody have any ideas ?

Re: More Friday Follies [7:29659]
John, First off I noticed many errors in my lame schematic. I was able to ping both 80.1 and 80.33. These are the 2 loops on R1 (OSPF router). There weren't 2 tunnels, there were two secondary address instead (sorry, but I was trying to remember from Sat). Need a secondary for each /28 subnet that you want to see on R1 (even tho R1 has /27's). Secondary addresses were inside the 80 subnet (not the tunnel source and dest as I said. Shows how bad my memory really is). I added R5 just to make sure that the advertisements would go beyond the tunnel (to prove that it's really an IGRP route). I don't see the stability prob that you have spoken of. Here is the important stuff : On R3 interface Tunnel0 ip address 172.16.80.3 255.255.255.240 secondary ip address 172.16.80.34 255.255.255.240 secondary ip address 172.16.1.33 255.255.255.240 tunnel source Serial1 tunnel destination 172.16.20.4 Works fine.

Re: Friday Follies Returns: WAS The old how to get routes [7:29259]
Chuck, Seems appropriate that you are due for some pain from the dentist after screwing up my day (and more than likely, my weekend) with this question. It is a very good question tho. Have been thinking about it for awhile and have it set up on my home lab. Obviously, if the masks were reversed on the routing protocols, it with be a trivial matter w/ an OSPF summary. How many routers are you using in this scenario? I am currently using three with the middle being the re-dist point (have 6 in my lab so I can make in larger). I recall the post from John N regarding the use of a tunnel for a situation like this. I believe the problem is that in this case it would require using a /27 mask in the IGRP domain. If the scenario calls for only /28 masks in IGRP, then this would be a violation. So, are the rules : 1. No default-network 2. No static 3. No policy routing 4. Only /28 in IGRP, /27 in OSPF Thanks, Gregg Chuck Larrieu wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... It occurs to me that there is another answer to this problem. So as a Friday Follies question: what is the other answer I came up with? Remember, the IGRP domain is /28 the OSPF domain contains routes /27 and shorter. You must assure reachability to all interfaces in the OSPF domain. You are not allowed to use a default network or any static routes to attain this end. for extra credit - make it funny.

The problem is one of those OSPF to IGRP redistribution with a twist. The IGRP domain is /28. So how to get those shorter /24 prefixes advertised. Oh yeah, you can't use the default-network command to create an IGRP default route. So let me offer this possibility. IP local policy route-map the route map then goes something like this: route-map igrp-default permit 10 set default interface [whatever the interface is] I also suspect that set ip default next-hop x.x.x.x works also, but at the time I was testing I hadn't thought through all the implications, and my test failed. In any case, the local policy would have to be implemented on all routers in the IGRP domain. A bit of planning, then, is required. I found out something else that was interesting. Local policy packets seem to have a particular way they are constructed. the first time I looked at my debug ip packet, the source address was one of my loopback addresses, which I was not advertising under IGRP. So of course my pings failed, because the distant end did not have a route back. So I deleted the loopback, tried again, and this time the source address was a LAN interface, this too not advertised under IGRP. I am assuming that Cisco has a hierarchy of interfaces. Usually a ping is sourced at the interface out which the packets are headed. But for local policy, it was different. Any case, I am offering these observations for consideration. Wish I hadn't turned my routers off last night. Or I could gather some screen shots.

Re: BGP and ip load-sharing [7:28960]
Dave, I have a dumb question regarding multiple defaults. Lets say that you had a multihomed BGP config connected to 2 different providers. Lets say that you had 2 routers below the firewalls sourcing the default. Then take a look at the routing tables below these 2 routers. Wouldn't nearly every routing proto (other than RIP assuming the hop counts were the same) only list 1 default? Wouldn't it be true that outbound traffic patterns would be based upon metrics from the routers sourcing the default? If this is true, then it's not really load balancing. I can think of scenarios were nearly all outbound traffic would be destined for only 1 of the 2 links. I'm sure I'm missing something dumb, but figured it was worth asking anyway.

Join the board and use whatever date you feel comfortable with. As far as the date is concerned, if you can leave on a weeks notice, there will be a seat available. Dates are always opening up. Just study with a March date in mind and you should be able to grab one within two weeks of the test. I'm pretty certain about this. Look at the scheduler and you probably will see Jan dates open. If I remember correctly Cisco testing is closed for testing from around the 20th till the new year. This might affect the availability of Jan dates in regards to my earlier statement. Just keep an eye open study your buns off and you should be able to grab the desired date as it approaches. -Original Message- From: Gregg Malcolm [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 11, 2001 11:02 AM To: [EMAIL PROTECTED] Subject: OT:Group Study LAB Board Question [7:28863] I recently passed my CCIE written. I am hoping for a Mid March lab date. Currently, cisco is showing only earliest available dates in June. I'd like to join the lab discussion group, but I have not yet schdeluded the lab since I don't want to wait until June to take it. Would it be an error in protocol to join the group saying that I have a mid March date? I'm am going to try very hard to get a mid March date (hopefully a swap).

RE: ATM circuit [7:28774]
Priscilla, I have to agree with you on this. I know of no method to carry ATM over an Ethernet. The opposite of course, is true. If the author would have said that ATM can run over chicken wire, I would find that much more believeable. ATM can run over nearly any phyiscal media. BTW - Do you encounter service providers at all? A Tranparent LAN (TLAN) is quite a popular term with them. Just a bridged 1483 PVC. Until I worked with that sector, never heard of it.

RE: Lab Attempt #2 - no go :- [7:28142]
Chuck, Thanks for the great feedback. Sounds like a killer. I'm taking the lab in a couple of months (failed my 1st attempt) and it was very helpful to hear your take. My question for you is, how much were you able to eat at lunch? Tests scores are directly proportional to the amount of food you consume at lunch. Correct this and you will pass next time.

RE: Serial Line is up and line protocol is up ANSW [7:27930]
Anil, I'm sorry, my explaination wasn't very good. The answer can't be B since you have no information saying data is being sent and received. The answer A does fit since a frame relay connection is active if int status is UP/UP. As far as the 2nd part, AFAIK not every encap uses keepalives. Frame Relay is somewhat special in that an UP/UP status really means that data COULD be xfer'ed. The case of the broken remote CSU/DSU does not fit this scenarios since keepalives would not be received. The question seems geared toward trying to trick the engineer into thinking that data is being xfered vs. could be. Many encap use keepalives. A few are F/R, ATM, PPP and HDLC (PPP uses an echo). Not sure if all do (probably not). Hope that helps.

RE: Serial Line is up and line protocol is up ANSWER [7:27930]
Maybe this will explain it..Just because a serial int is UP/UP, it doesn't necessarily mean that data is able to be xfered. The serial int could be connected to a CSU/DSU which might give the int the correct control signal states to make the serial int appear to be up (example would be that the remote CSU/DSU is broken but carrier signal is up on local int). In this case, since it's frame relay, the 2nd up would not occur unless LMI keepalives were occuring. What cisco is saying is UP/UP is just the int status. Doesn't mean that data is being xfered. The most popular way to know that an interface is in use is to watch in/out stats (via sh int). Clear counters is another usefull cmd.

RE: Variance [7:27882]
Gaz Howard, Thanks for the input. I really appreciate it. I'm still a little curious. Based upon the link Gaz included, we know that variance is factor based. Consider the following. 3 paths; 56 Kbps, 128 Kbps and 256 Kbps. If we use variance of 2, the 128K and 256K paths will be used in a load balancing fashion. I'm still wondering (and need to research cisco.com) about how it done. More than likely, it's something like CEF based (by dest). Thanks again and I'll post something about this when I find out.

Variance [7:27882]
I have a question about variance that's been bugging me. I know that metric based routing proto's (IGRP, EIGRP and OSPF) will not load balance across unequal cost links by default. We must use that variance cmd. The variance has a multiplier. 1 is equal cost. I assume that variance is done per packet (as opposed to session). Is this true? If variance is set to 2 does it mean 2 packets would be sent out high bandwidth link and 1 packet out the low bandwidth link?

RE: Variance [7:27882]
One note - I also wonder if 'no ip route-cache' might force variance to balance per packet if that's not already the default. Just curious.

RE: OT - Emergency [7:27627]
Try both the ami and asx logins. If these do not work, do the following (Should be same procedure in FT 7.x). 1) Reset the SCP with the paperclip. 2) Depress both the 'Next' and 'Select' buttons after 'decompressing' scrolls (before 'done' appears). 3) Enter 'N' when the console message asks to boot without reading from flash. 4) Clear the ami password (Y/N)? Y It's been awhile since I've done it, but this should work. Post another message if you have problems. I have a Marconi TAC account.
