Help! Locked out of my 7513 Router! [7:16770]
Dear Cisco Groupstudy Person: I locked myself out of my Cisco 7513 router somehow.My Keyboard has no effect. I'm not sure if this is the reason, but my most recent configuration change was to fill the No. 4 slot, previously blank, with a Fast Ethernet Card. Everytime I power cycle the router, it comes up again, goes through the boot sequence, and then freezes with a string of messages concerning the status of FE 3/0 and FE 4/0, first stating that they are up and then stating they are down. Even the password recovery technique where one uses the "Break" or "^[" Keys and then resets the Config Register can't be used. For some reason, the keyboard won't even work; it has no effect in this situation suddenly!!. I have carefully checked my Hyperterminal settings of 9600 baud ; Data bits=8 Parity=none stop bits=2 Flowcontrol=none Anybody have any idea why my keyboard is "dead" I am working with Vlan configurations on this Router. Please help! Thank you.

Re: BGP Bandwidth [7:13817]
You could of course set it up so that you will enjoy the full bandwidth of all 3 T1s lines with redundancy. Run a search on BGP multihoming on Cisco's site or Groupstudy archives. That should give you enough examples to start with.

match ip route-source without ACL? [7:13813]
Hello, I got some questions when using the "match ip route-source" command and would appreciate any input: 1. I was trying to set the metric for all the igrp routed redistributed into ospf t0 2600 using a route-map. Originally the route 12.0.0.0 showed up with a metric of 20. r3#i 12.0.0.0 Routing entry for 12.0.0.0/8 Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric 64 Redistributing via ospf 1 Last update from 135.1.20.4 on Serial0, 00:26:01 ago Routing Descriptor Blocks: * 135.1.20.4, from 135.1.14.4, 00:26:01 ago, via Serial0 Route metric is 20, traffic share count is 1 2. The I added a route map igrp-ospf and applied it to the ospf redistribution process. route-map igrp-ospf permit 10 match ip route-source 15 set metric 2600 r4(config-router)# redistribute igrp 1 subnets route-map igrp-ospf 3. I had thought that I have will have to add an access-list 15 before I see the metric changes, surprisingly, I noticed that the metric changed right away without a ACL 15... r3#i 12.0.0.0 Routing entry for 12.0.0.0/8 Known via "ospf 1", distance 110, metric 2600, type extern 2, forward metric 64 Redistributing via ospf 1 Last update from 135.1.20.4 on Serial0, 00:00:13 ago Routing Descriptor Blocks: * 135.1.20.4, from 135.1.14.4, 00:00:13 ago, via Serial0 Route metric is 2600, traffic share count is 1 4. According to cisco's site, the usage for match ip route-source says "To redistribute routes that have been advertised by routers and access servers at the address specified by the access list". It is kind of vague and doesn't explain why I can change the metric without specify ACL... Any ideas?

Assuming that you are talking about DHCP client, you need an IOS that supports DHCP client feature. I believe that it is not supported until some 12.1(x)T version. Once you got that from Cisco's site, you should be able to configure one of your interface to get an IP automatically from your ISP.

Re: advertising IP blocks [7:11191]
Daniel, Unless you are going to get your own IPs from ARIN, you don't have to worry about getting anything smaller than /24. Just like John said, if you are using IPs assigned from ISPs, they should do the aggregation job for you to make sure your IPs get global routability. If you could get two circuits from these two ISPs(make sure that they don't use the same carrier if you could...) and run some kind of dynamic routing protocols with these two ISPs. That would definitely give you the level of redundancy you are looking for. The only problem I can think of is that you might need to make quite a few changes in your network as you would be getting two blocks of IPs from these two ISPs. e.g. load-balancing.

Re: Information about Nortels Shasta 5000 [7:10809]
At least last time I checked over the Shasta support page, there are only a handful of documents over there. They really should have spent more time on this as the box has tons of new features. I am sure shasta support in Nortel GTS would be happy about this as well. ^__^ The things that I really like about the Shasta5000 is shasta's effort to make it a wholesale aggregation device. The idea is that service providers can throw DSL, dail, wireless, FR, ATM and cable all into this box and then you can apply customized global policies to these subscribers. I look at this as a great way to introduce value-added service, especially these days when everyone is talking about profit. Two features that I tried before were the firewall service policy and the captive portal service policy and they both work very fine despite some minor bugs. As other posts mentioned, the main way to configure the box is through a GUI interface which makes presenting a sample configuration difficult. I hasn't get a chance to see the Cisco ESR 10008 and 10005. However, I did compare the shasta with Redback/Cisco 6400. Taking everything into consideration, I would perfer the shasta5000 over the Redback/Cisco 6400 as an aggregation device. Hopfully Nortel will stick with it rather than cut it off...

Re: Information about Nortels Shasta 5000 [7:10809]
I have been dealing with these shasta boxes for a while. One thing I am pretty sure is that even Nortel Shasta won't have too much documentation for their own engineers... Therefore, your best bet to learn about this box would be to check your SE or through "trial and error", which is what I did... There are some bugs in both software and hardware side of the box and that java GUI interface is really slow... However, I do have to say that I am very impressed by the design of the router as it has quite a few nice features for an aggregation device that at Cisco/Redback doesn't have. For example, the content management features are really neat and I can see it as a very scalable solution. As long as Nortel keeps supporting Shasta, I think this box has some great protential and I will keep an eye on it.

Re: weird BGP question [7:10384]
This is indeed an interesting question although I never heard that it is being done... If I were to take a guess, it would be to manipulate traffic so that upstreams A would always be preferred. (append extra AS paths and a default route should do the trick). Then there has to be some kind of network management tools to send out alerts when the accumulated traffic for upstream A reaches 300G. At that point, you can tell the router to take B as preferred while put A as backup. Your upstream provider might have a traffic monitoring web page that you can log into to view the same results.

Re: what is loopback interface for ? [7:9493]
I can simply use the quote from Michael Williams' message above to answer your question... 1. "A loopback is a logical interface that never goes down. It's used for various reasons (for setting up various kinds of tunnels, for setting who is the DR/BDR in OSPF, etc)." 2. "Many people use the subnet mask 255.255.255.255 because that's the only way to assign a single IP to the lookback instead of using more than 1 IP address." Therefore, you normally won't see /24s on loopback interfaces.

Re: POP relocation [7:9897]
Since you did not mention for sure whether you would switch ISP or not. 1. If you stay with the same ISP, they should be able to let you keep the same IP number especially for those 2 /24s. If they plan everything ahead of time and you keep the old IPs, it is indeed only going to be couple minutes of downtime and you don't have to do anything on your router. Of course, this is based on the assumption that they have good network engineers over there taking care of your case. 2. If you are going to switch to another ISP, you would probably have to change your IPs since you don't own those /24s. Theoretically, those two ISPs could make arrangements to let you keep the old IPs. However, it is going to be a big hassle and you would find it not worth the effort.

Re: Two DSL circuits for Fault Tolerance [7:9200]
I discussed fault tolerance a lot before with customers who has a web site that would like to be up all the time using DSL lines. As far as I can tell, there is just no easy way to achieve a high-level of fault tolerance without running some kind of dynamic routing protocols with your ISP. Your idea of using two DNS servers won't work. When anyone tries to send an email, their smtp server will randomly pick one of the authorized name server requesting for your IP address. Therefore, you would still have 50% chance of failure if one of the DSL is down. I would recommend that you get some kind of load balancing device in front of these two DSL lines. Or, if mail is all we are concerned about, you could assign one IP from ISP A as the primary MX record while use IP from ISP B as a backup MX record. That will make sure your mail always get to the exchange server. BTW, I would not recommend using a second DSL line to backup another DSL line since both DSLs would probably go into the same DSLAM in the same CO anyway... Richard ""Steven V.

Re: Load Balancing for Applications [7:8260]
Assuming that you have a router at home that you can plug both the cable modem and DSL in. If you only need to get hold of a specific IP (game server ) throught the DSL while everything else through the Cable, you could simply configure default route for the Cable while adding a static route for the game server IP with the DSL ip as gateway. However, it would be more complicated if you want to load balancing using different port numbers. You probably would have to setup something like policy routing to achieve this.

OT: power requirements for home lab? [7:8070]
Just a quick question for those of you who have dealt with a home lab before: Currently I got 5 2500, 1 2926 and 1 4000 and just realized that I probably want to make sure that I don't blow my circuit-braker off once I turned all these on at the same time. According to Cisco's site, the 2500 would take roughly 1 amp, 2926 would take 3 amp while I could not find anything for the 4000( it only says 200 W). So I am just curious whether anyone has done any study on the power consumption of these various Cisco gears. BTW, stupid question, anyone know how many amps would a normal desktop PC take? Thanks!

Re: IBGP multihop?
Thanks for all the recommendation from the group. I finally figured out how to make it work... Originally, on R2 , there is no route to 3.3.3.3, the reason why it is pinging is because of the default route. Same on R3. I ran "debug ip bgp out" and got the following error: 23:48:57: BGP: 2.2.2.2 multihop open delayed 13727ms (no route) 23:49:11: BGP: 2.2.2.2 multihop open delayed 16256ms (no route) 23:49:27: BGP: 2.2.2.2 multihop open delayed 13949ms (no route) 23:49:41: BGP: 2.2.2.2 multihop open delayed 18975ms (no route) 23:50:00: BGP: 2.2.2.2 multihop open delayed 19711ms (no route) For some reason, the BGP neighbor setup process won't take default route. Therefore, I tried to add static route for the loopback interface and then the bgp session finally came up. I would imagine using IGP to carry the loopback address should work as well.

IBGP multihop?
For EBGP, you can use the ebgp-multihop command when the neighbors are not directly-connected. I was just wondering whether there is a similar work-around that anyone know of for IBGP. Basically, I am using loopback interfaces on these two routers and they have to go through another hop before hitting each other. I configured IBGP on these two routers with those loopback addresses and found out that the BGP session can't be formed...

Re: CID 3.0 study material/books?
Well, I used the CiscoPress CID book and that's probably all you need to prepare for this exam if you already had your CCNP. Note that I would only recommend this CID books for those who want to take the CID test. I don't think it is a good Network Design book, you should have other reference materials so that you know how to deal all those unclear points in the Cisco CID book. ^__^ Richard Li Li Zhao <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Dear group, > > Pls advise me the study materials for the new version > of CID 3.0.
