Re: 7507 rate-limit [7:54987]
Sorry, wrong choice of words perhaps. What I mean is to use the policing features of ATM. I believe using CAR will take up more processor power as compared to using the ATM policing.

Re: Confused about MTU size [7:54689]
I am interested to know what are the applications out there that sets the DF bit . Does anybdy know and common ones ? The reason for this is because I want to run LFI on my router for the purpose of VoIP. If I understand how LFI works, it will "chop" up large data packets so as to reduce possible jitter. If there are critical applications that don't allow fragmentation, my guess is LFI would cause the packets to be dropped. I don't want that to happen. Any suggestions what I could do besides throwing BW at the equation and turning off LFI altogether ?

Re: OSPF Default Routing [7:46111]
Hi, If you look at the lab walk through on page 817, you will notice that the statement "default-information originate always route-map condition" The default route will only be propagated if the condition listed in the route-map statement is met. If it is not met, the default route will not be propagated. Things would be alot simpler if you just took out the "always" statement, but then again, the CCIE lab requirement may require it.

Re: Wanna Be a CCIE? Try This One [7:6076]
Giles, I don't think its a OSPF Cost problem. I tried it without avail. I am not very sure but I believe OSPF will prefer Intra-Area routes despite having an alternate path that seemingly has a lower cost. Please correct me if I am wrong. Could this be an administrative distance thing? As much as I would have liked to come up with an ingenius solution, I was not able to. I have since changed Area 1 into Area 0. It works fine now but I have this nagging feeling that something more constructive could have been done. The solution I adopted seems more like a cheap work around. But I guess it works and that matters more. By the way, the network is much bigger than what I have illustrated. It consist of around 40 routers spanning over 16 countries. Its a private IP network that runs on MPLS to provide VPN's. My next project would be to implement traffic engineering.

Re: Wanna Be a CCIE? Try This One [7:6076]
Thats a good point James. Distribution lists are too restrictive and not very scalable in this situation. I think my first course of action would be to tweak the OSPF cost between A and C so that traffic from A to D will go via B instead of C. My only concern is that I might create the situation where traffic from A destined for C goes via B !! This would just be creating a new problem.

Re: Wanna Be a CCIE? Try This One [7:6076]
Peter, Thanks for your input. I hope my description of the geographical topology in another post should point out why I want my traffic to route in the manner I have described. Taking down the link between C and D is not an option. You mentioned Virtual links. I always thought they were used to link an area to area 0. I don't see how it can be applied to my case. I can take the easy way out and place all the routers in area 0 but want to use that action as my last resort. kevin ""Peter I.

Re: Wanna Be a CCIE? Try This One [7:6076]
Thanks for the recommendations. Firstly, let me explain why I need the routing to behave in such a way. The reasons are purely geographical and I want to reduce latency. Routers A and B are in London and connected back to back via FastEth. Routers C and D are in and SanJose and NewYork respectively(Connected to both London routers via FR). I certaintly won't want traffic originating from RouterA ( London ) destined for RouterD (NewYork) to have to go to SanJose first. It would be much better if the hop is A-B-D instead of A-C-D.

Re: Wanna Be a CCIE? Try This One [7:6076]
routerArouterB AREA0AREA0 || routerC routerD AREA1-AREA1 Since we are on the topic of OSPF, could someone help me out on the scenario above? Routers A and B have interfaces in Area 0 and Area1. I want traffic from routerA destined for routerD to go via router B. This is not the case in my network because I realise that routerA prefers Intra-Area routes and thus would route traffic to routerD via routerC. What tweaks must I make in order to force the traffic from routerA to routerD to go via routerB ? Someone suggested building a GRE tunnel between routerA and routerB and then configure the tunnel to be in AREA1. Any suggestions? Kevin ""W.

Re: Is it really worth it? "CCIE" [7:5725]
Did you know that many of the top Cisco engineers are not CCIE qualified? I have always wondered why people like Sam Halabi and the likes do not get certified.A Cisco employee told me that these people have everything to lose and nothing to gain if they take the CCIE exam. If they refrain from taking the tests, their reputation stays intact. If they take the test and fail, people will start to question their credibility.

Re: Passed BCMSN [7:4546]
Please don't get me wrong, I am not advocating memory work without any hands on experience. I just wanted to correct the person who mentioned that one requires practical experience to pass the BCMSN exam. If I had a choice, I would have loved to build a multilayer swithching lab to practice on, but the truth of the matter is that I did not have the resources. If I had put that obstacle in my path , I would have never gotten my CCNP.I pursued my CCNP for the purpose of gaining sound fundamentals in networking issues and to see the broader picture. I strongly believe that if want to pursue a certification to prove your salt in "hands on" work, go take the CCIE. I really wonder why employers don't set up a lab tests to select job canidates.

MPLS and CoS/QoS [7:4016]
Hi, My company has recently set up international IP network that runs MPLS. We have already successfully provisioned VPN services on this network. However, the next phase would be to turn on classes of service mechanisms like WREN,WBFQ and CAR functions. We are aiming at providing three classes of service. The first class should guarantee latency and packet loss and if possible BW. The second class will just guarantee latency whilst the third class will offer best effort traffic. I would appreciate any advice the group can give with regards to implementing these classes of service. What happens if a customer pays for 3 different classes of services at varying bandwidth settings (using CAR) . What happens to out of contract traffic? If I rate limit my premium traffic to 30% of the trunk, what happens when I pump in more than that? Would it spill over the the other classes? I can I monitor the amount of "spill over" traffic so as to advise the customer to increase the size of the premium class trunk? Thanks in advance for your advice!

Re: OSPF dropouts [7:3964]
I am not sure if this is a OSPF related problem but I recently encountered a strange problem in my network. I have a WAN link that has been running on frame relay encapsulation for the past few years without any problems. Just today, I noticed that I lost connectivity between site A and site B (these sites are directly connected) .The first thing I did was to do a show int on both ends. I found both the line protocol and interface to be up. I however, could not ping the two ends. I couldn't even ping the WAN interface of the router that I am connected by console to. How is that possible? Should I do a shut , no shut? Another interesting thing I discovered on this router (7500) is that when I ping the WAN IP address of other interfaces, I get a round trip delay. I always thought that since the IP address is assigned on that router, the ping should be less than 10ms ?? I run OSPF,BGP and MPLS. FR guys says that there is no problem with the PVC. I would appreciate any help rendered. Thanks! Kevin wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I have had similar problems to this with OSPF.
