However, the IOS-based command sets on the 3524XL and 2900XL series switches are very similar to the 3550 and would allow you to practice IOS-based commands and learn the Layer 2 functionality. Still, in my opinion, your best bet is to either purchase a 3550 or rent some 3550 rack time.

CCIE Written Study Material [7:55987]
Hi, Group. I wonder if anyone can recommend some study materials for CCIE written. I am now using Doyle 12, the Caslow book, Cisco Lan Switching book, but still there are a lot of stuff on the blueprints these books don't cover. I tried to read some of the white papers on cisco's site, but there are so many of them, I am now a little lost navigating the white papers. For those of you who passed CCIE written recently, do you mind telling me what study material you used? I would appreciate any direction you can give me. Thanks in advance.

Re: Update: OSPF Route mystery - what am I missing [7:55975]
in line ( like the skates ) Nigel Taylor wrote in message news:200210202246.WAA27657;groupstudy.com... Chuck, I can't believe anyone understood a word I wrote. After reading my post I could only laugh. Nonetheless, I think you got what I was trying to say and I do believe your thoughts and observations are correct. In reading your post I was trying to recall what could have possibly provided the material for the discussion you mentioned. The author that comes to mind is no other than Terry Slattery. CL: Slattery remains an interesting read. A lot different, and maybe not a landmark work, a la Doyle, but still worth looking at. I too did notice the constant flapping of R4's common network using the debug ip routing command. I must say this is definitely interesting. Lately, I've had the opportunity to look at a few situations where the use of RIP lead to some very unique results as it pertains to redistribution. (check this one out... http://www.cisco.com/warp/public/104/10.html). Look at the route table on r2504 take note of the 3.22.x.x and 3.44.x.x networks. Why is it on r2507 that the routes show as ospf exteranl type2 routes. This is just another example of how rip simply works outside of the rules. CL: I was going to say that it's because the routes are RIP routes that have been redistributed into OSPF. However, looking at the configuration, I see the interfaces are in the OSPF domain as well. Maybe the configuration is being misreported? Maybe if an interface is in both a RIP and an OSPF domain, RIP takes preference? That can't be right. CL: hhhmmm.. fooling around with the configs a bit. Mystery upon mystery. I can't duplicate the result on the CCO link below. I'm wondering if there are some IOS bugs. CL: the other thing I got to wondering is if there is some provision in the standard in the case of multiple ABSR's advertising the same route. I can't find anything off hand. It might require a more careful read than I have time for right now. Although, at first look everything does seem to be very straight-forward, not until you get under the hood do you really see or observe the real issues involved. Thanks for keeping us all sane :-) Nigel - Original Message - From: The Long and Winding Road To: Sent: Sunday, October 20, 2002 5:33 PM Subject: Re: Update: OSPF Route mystery - what am I missing [7:55975] funny you should mention it. I've spent the last forty minutes looking at debugs on all of the routers involved. given the topology, R1tr--R2 | | | serial |serial | | R4tr--R3 R1, R2, and R3 are OSPF routers R1, R4, and R3 are RIP ver 2 routers 2 way redistribution occurs on R1 and R3. The configurations for redistribution are identical on both routers-- here is what I believe I am seeing: R4 is advertising RIP routes to both R1 and R3 R1 and R3, in turn, redistribute those routes into OSPF as E2's R2 receives those routes and installs them into the routing table. However, shortly thereafter R2 flushes those routes. Why? Well, looking at the debugs on R3 and R1, what is happening is that the E2 routes are replacing the RIP routes on R1 and R3. Then, depending on the timing, the R4 routes show up in the R2 table sources from one router or the other. When I turn off mutual redistribution on R1 and R3, I start seeing results like this: O E2160.160.30.0/24 is possibly down, routing via 160.160.255.2, TokenRing0 O E2160.160.31.0/24 is possibly down, routing via 160.160.255.2, TokenRing0 O E2160.160.32.0/24 is possibly down, routing via 160.160.255.2, TokenRing0 O E2160.160.33.0/24 is possibly down, routing via 160.160.255.2, TokenRing0 O IA160.160.39.0/26 is possibly down, routing via 160.160.255.2, TokenRing0 Note that 160.160.3X.0 routes originate on R3. I have similar things happening on R3 With mutual redistribution turned on, the situation is a bit different. The routes just go round and round from router to router, being distributed and redistributed forever, so that even though the domain is unstable, to the casual eye, everything is fine. All routes are reachable, although not necessarily via the interface over the protocol one would hope Nigel, I believe we have had this conversation before - about where the redistribution process goes to get the information it uses in the redistribution process. It is reasonable to think that when one redistribute OSPF into something else, that the redistribution process goes to the OSPF database. For rip, where can it go but the routing table, and if all the RIP routes have been replaced by OSPF routes, then it has nothing to redistribute? Not saying this
Re: Frame relay circuit speed from IOS? [7:55908]
If the frame relay switch is reporting it (it may have something to do with the type of LMI) you can use show frame-relay lmi to get the CIR.

Sorry for the misunderstanding, guys. I got to thinking more about this and I guess I wasn't thinking of the MSFC, just the 6500 switch itself. I work with 6000's with MSFC's and it should have slapped me in the face right away that there were similarities.
