Symptom: 3640 router reboots itself over and over again!! [7:18674]
Hi all Have anyone encountered the situation that the 3640 router rebooted itself over and over again? I don't think it is the crashed flash memory because I booted off the flash card and it showed the same symptom. This is the first time I have ever seen this kind of issue. Thanks in adv.

Looping up remote csu !! [7:14384]
Hi all 3600A--csu-private line-csu--3600B In this environment, I am at 3600A router. I was wondering if I could loop up remote csu(3600B side) by configuring 3600A router instead of having telco do that for me. I remember that I have done this before between 7200 router and 3600 router. I was also wondering if I could do with even lower model of routers, such as 2600s and 2500s. Would it be possible?

BGP Bandwidth [7:13817]
Hi all I am trying to implement BGP. I used to have 2T1 lines going straight to Qwest (isp). Now I want to install another T1 line going to ATT (isp) as a back-up line. Now my question is what bandwidth will I have? Will I have 4.5M bandwidth (2xT1 + T1) together? or Will I have only 3M bandwidth (2xT1) from Qwest because T1 going to ATT is used as a back-up? It would be better if I could use extra T1 not only as a back up but also as an additional bandwidth. Your input will be appreciated.

Primary and back-up line at Frame-Relay [7:12580]
Hi all We have Frame-relay network using EIGRP as a routing protocol. There are two main head quarters; one in San Jose and one in New York. All the branch offices ( spokes) has redundancy lines; one pointing to San Jose router and the other one pointing New York router. I want spokes at the western region to use San Jose router as a primary router and New York router as a back up circuit to get to internet. Also I want other spokes at eastern region to use New York router as a primary router and San Jose router as a back up router. What should I put in config on spoke routers to implement this performance? For the reference, here is a part of config on one of spoke routers that is performing redundancy properly. interface Serial0/0.1 point-to-point description PVC to San Jose ip address 172.16.249.42 255.255.255.252 bandwidth 1544 frame-relay interface-dlci 115 ! interface Serial0/0.2 point-to-point description PVC to New York ip address 172.16.249.46 255.255.255.252 bandwidth 1544 frame-relay interface-dlci 312 ! interface FastEthernet1/0 no ip address shutdown ! router eigrp 1 network 10.0.0.0 network 131.119.0.0 network 172.16.0.0 network 192.187.128.0 network 198.211.28.0 network 205.227.143.0 network 206.214.16.0 ! ip classless ip route 0.0.0.0 0.0.0.0 172.16.249.41 ip route 198.211.28.64 255.255.255.192 198.211.28.123 ip route 205.227.132.208 255.255.255.240 161.69.241.209 Thanks JP Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=12580t=12580 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
redistribute subnet vs. redistribute connected [7:12103]
Hi all One is ospf's subnet command: redistribute subnet The other is eigrp's connected command: redistribute connected Are these two kind of same? I know that without subnet keyword, ospf's routing table shows only major network address that are not directly connected the redistributing router will be redistributed. I was wondering if this is true for eigrp's connected Thanks JP Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=12103t=12103 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Output of sh ip route connected [7:11266]
That's what I couldn't figure out. I think 10.20.1.104 must be host ip address, not network address. Am I understanding wrong? Like you recommended, I was able to ping 10.20.1.105 and 10.20.1.106.

Disappointed with CCNP --Original poster
Hi group members!! I am the original poster of this thread. First of all, I appreciate your encouragements, concerns and even criticizing point. I received more replies than I expected. There were some people who made a point on removing my ccnp cert from my resume. It was not only thoughtful suggestion, but also scary suggestion, because I felt that removing it from my resume was like 7 months of ccnp prep going down the drain all of a sudden. However, I made up my mind not remove it. My intension of listing ccnp on my resume was to show how much interest I have on networking. I believe that there is clear difference between ccna without experience and ccnp without experience. If I were employer, I would hire ccnp without experience because there is obviously difference between these two guys in terms of the amount of technical knowledge and potential performance that he or she might make. As some members mentioned, lots of people consider their careers from IT industry because of money. I agree with them not only I am partly one of them, but also money can be one of strong motivation in advancing their living condition. But money doesnt give me enough motivation as my interest in networking does. I didnt even consider CCNP. I was going to start to look for a job after I got MCSE and CCNA certifications. But I couldnt stop my interest in knowing more on network knowledge. There might be some people who would say, none of these guys would be hired. Well, the biggest irony that I have is that who is going to start his or her career in IT industry if everyone is looking for only experienced engineer. That is why I am looking for entry level of job. I wouldnt be able to perform in the beginning as much as years of experienced CCNP would do. But I am sure that I could learn things faster than most of entry-level job applicants. If nobody offers me a job, I would go for CCIE without any corporation experience. I would buy network devices, and take ccie lab classes. I wonder if there is anyone who made ccie without any corporation experience. I wish there were. If not, I will be the first one who becomes ccie without experience. I am not talking about home-network or training school network experience. I am talking about the experience that can be obtained as a network engineer. I know it would be harder to become ccie without real world experience, but I believe that lots of members who showed their concern would be with me. When I become CCIE, I will put nothing but CCIE, and see if anyone gives me job offer. I wonder if people who emphasizes on only experience still wouldnt hire me. For the people who are already out there and working for company without any certification, I respect them because they might have had harder time on getting a job than I do. Since I posted my message, I had some job interviews. Well, I will see how it will go. Once again, Thanks you for encouragement and advices. I will definitely let you know if I got hired. jeongwoo __ Do You Yahoo!? Yahoo!

newbie question on Frame Relay!!
Hi all I have a quick question. On the traffic between central router and branch office router on frame relay, how could central router's connection rate to FR cloud be different from branch office router's connection rate to FR cloud? I could understand if cloud had traffic congestion. But when there are no traffic congestions, how could they be different? These two routers are using same mechanism, Frame Relay, which gives relatively high-speed transfer rate. I happened to ask myself this question while I was reading about FR traffic shaping. Traffic shaping could be useful under this situation. ( according to the book) Could anyone give clear answer? I appreciate your reply. jw __ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.

RE: newbie question on Frame Relay!!
Mike First of all, thanks for your reply. I didnt know there was such a thing as physical access circuit going to providers access switch. All I was thinking as a connection mechanism was PVC. I understood that central routers sending rate could be different from branch offices receiving rate because of, as you explained, different physical access circuits to FR cloud. However, I got new question derived from your example. How could each pvc transfer rate be calculated? When central router has T1 connection (1.544 Mbps), and there are 4 pvcs, then each pvcs transfer rate would be 1.544M/4=386K? If it is, the companies that have 30 to 50 branch offices around the country would have not very fast speed rate? Or am I understanding something wrong? As far as I the traffic shaping was concerned based on what I understood from the Cisco book, I thought that traffic shaping would be configured on central router which sends more traffic than a branch office router can handle. But you mentioned that traffic shaping comes handy by throttling the traffic coming from branch office router. It sounds to me that traffic shaping is configured on branch office router. Isnt that supposed to be configured on central router? I will appreciate you reply. --- "Coker, Michael" [EMAIL PROTECTED] wrote: jw, When using Frame Relay the router will have: - a physical access circuit (this is the circuit between the router and the Frame Relay provider, i.e. T1) - a PVC or SVC (this is the "virtual" circuit through the Frame Relay cloud to the other router) The physical access circuits can be different for each router. However, a PVC connected between Router A and Router B will be the same speed. I think you may be confusing the two types of circuits. Example: Router A (main branch router) can have a single T1 to the Frame Relay provider (CO). This would be the Physical Access Circuit. Router A could then have multiple PVC mappings, let's say 256k each, to multiple branch office routers (i.e. Rtr B, Rtr C, Rtr D, Rtr E, Rtr F, etc.). All of these branch offices may have 512k physical access circuits to the Frame Relay cloud, but it's the PVC's that will have the same transmission rate (256k each) back to Router A. Traffic shaping comes in handy when you have multiple PVC's that basically oversubscribe your T1 (meaning the cumulative amount of PVC's, in bps, is more than the bps of the physical access circuit of Router A). Traffic shaping allows you to keep from oversubscribing your central router by throttling the amount of traffic transmitted by all of the other branch offices. Hope this helps.

Re: Which one is correct?
Sorry for the unclear question. What I was trying to ask was the FR configured with Multipoint. When multiple PVCs are configured in a subinterface of the central site router, I was wondering how many local DLCI numbers are needed. There are three branch offices, and each branch office has two PVCs going to central site router. Then there will be totally 6 PVCs in this whole structure. From the view of central site, its router has three subinterfaces, and each subinterface has two PVCs. Now, how many DLCI numbers do I need totally at central site router? Would it be 6 because there are six PVCs? or Would it be 3 because there are three subinterfaces? I hope this question is clearer. --- "Peter I. Slow" [EMAIL PROTECTED] wrote: It is quite an unclear question. first, at least one pvc will need to be setup, no matter how you look at it; subinterface or not. at any type of central site, i reccomend using subinterfaces, this way you when you go to expand, you dont wind up with an inconsistent config. everything will be on subinterfaces, and when you type show run, you rconfig will be prettier. from your "description", it is not apparent if you need point-to-multipont or point-to-point subinterfaces. jeongwoo park wrote: Hi all.

Re: ISDN Backup
Why would you need to have primary router and backup router implementing HSRP even if you had primary interface and backup interface? You could do it with one router instead of two. jw --- michael owuor [EMAIL PROTECTED] wrote: Chris, What are the specific problems you are seeing the T1 comes back up? The only routing issues I would look for would be to make sure you have recursive routing configured wherever you have IP unnumbered configured. Either that, or I would get rid of ip unnumbered alltogether since this is a private network, and there is no risk of running out of IP address space. Does the ISDN router have a recursive host route to the 2.1 address which says it is reachable through the BRI/dialer? I think the easiest/cleanest way to do his would be to run the routing protocol, and have the Remote ISDN router do the dialing when needed. Have the Central router advertise a default route to the Remote T1 router, which would also have the floating default route pointing to the ISDN Router. When the T1 connection is lost, the floating static route is installed, and traffic is directed to the ISDN router which only needs a static default route going out its BRI. Since the remote routers share a LAN segment, you could also look into implementing HSRP where the Remote T1 router is confiured as the active router, and therefore receives all traffic from the LAN users who need to get to the Central site. If that router fails, or if the T1 interface goes down, the ISDN router now becomes the active router and receives the traffic from the LAN users and sends it out the ISDN interface. A combination of floating static routes with a dynamic rouing protocol and HSRP is a good design to go with, since you achive redundancy on layer 1, 2 and 3. Floating statics with a routing protocol ensure the Remote T1 router is notified when, for example, the T1 interface on the central site goes down. In such a case, the T1 interface on the Remote could stay up and floating statics alone would not notify the Remote T1 router of the loss of connection. The dynamic routing protocol will. HSRP allows the ISDN router to be notified when the T1 interface or the ethernet interface on the Remote T1 router goes down, or when the entire router fails. michael a.o From: "Chris Sees" [EMAIL PROTECTED] Reply-To: "Chris Sees" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: ISDN Backup Date: Thu, 9 Nov 2000 14:21:21 -0500 Hi, I'm having some issues with ISDN backup failover and hopefully someone has done this before. -Central site with a dedicated T1 through serial int. to Remote site router -Central site also has a ISDN to Remote site to a second router The Central serial has the BRI as a backup.

Hi all Lets say there are 5 subnets (Class B/16 subnet mask) consisting of approximately 500 DHCP clients and 20 servers. Someone as a Network Expert suggested flattening the network. As a Network newbie, I simply followed the instruction from the book on how to supernet, and finally summarized those 5 contiguous subnets into following address: 123.80.0.0/14 (**this is a made-up number) Now I am done with supernetting.

Broadcast Suppression!!
Hi, I have a customer who wished to enable broadcast suppression for a new network we're building. Generally I've never used it - I normally like to keep switch configurations as simple as possible. However I have no reason to tell him not to. It's a good feature, and broadcast suppresion is one of the reasons I recommend keeping VLANs smaller rather than bigger (where possible - lots of other things ocnsidered of course). However I am wondering what's a good limit. Years ago, it was said 100 broadcasts per second was a good value - this equates to about 12% of Ethernet if the broadcast are full length packets. These days things are a bit different with Pentium processors on hosts, and FastEthernet. I was thinking of simply setting all ports to 15% as the broadcast threshold, however if some ports are 100Meg and another 10Meg, then 15% of 100Meg will kill the 10Meg ports. Therefore I would be looking at seting 15% on 10Meg ports, and 1.5% on 100Meg ports. This is the sort of thing I wanted to avoid - differenting settings on different ports etc. Any advise - any horror stories I should perhaps know about. Thanks __ Do You Yahoo!? Thousands of Stores.

subinterface!!
hi Brian. I have a quick question from what you mentioned regarding multipoint subinterface that I have always been wondering about.

Two DLCI numbers?
Hi all While I was reading a cisco book, I came across the fact that DLCI number has only local significance because there might be more than one DLCI number associated with one pvc. Why would any pve in frame relay network have two DLCI numbers? I know that DLCI number is given by frame relay service provider. Can someone explain this? Thanks in adv. jeongwoo __ Do You Yahoo!?

Thanks for your response. I forgot to mention that primary link is frame-relay and backup link is isdn link. Our company has HQ in San Francisco, and 4 branch offices are located around bay area. Not as a network expert, but as a ccnp wannabe, I was curious which router would initiate isdn backup link first between HQ router and branch router.

Which router detects the link failure first? what decides which router does first? You should really specify what they have as backup in the first place. There are many different ways of backing up lines from HQ to branch. Some examples: On a router you could have serial 0 as the primary and then a lower bandwidth serial 1 as the backup. To do this, in interface s0 you would place "backup int s1 0 300". The 300 being the time s1 waits to go back down when it realizes that s0 came back up. If you are using HSRP then you would have 2 devices. One would be the active and the other on standby. All info is passed through the main until it goes down and then it automatically starts going through the standby which has now become the active. These both have much more detail to them but instead of me going into detail, I'm sure you could just read up on them. The book would be more accurate them me for sure. Hope I helped...

Re: static route question ??
Thanks for your reply Just want to clarify what I meant. When I said that static route gives us faster traffic transmission, it meant that static route's administrative distance is 1, which is lower than other dynamic routing protocols' administrative distance. Can I say this? Please correct me if I am wrong. Thanks in adv. jeongwoo --- Priscilla Oppenheimer [EMAIL PROTECTED] wrote: Just being picky, but I can't see how static routing would give you faster traffic transmission than dynamic routing. The router still looks into the routing table and finds a route for the first process-switched packet. From then on it uses the fast-switching cache, (unless configured not to do so.) But just because it's a static route instead of a dynamic route doesn't make it any faster. Static routing uses less bandwidth because no routing updates are sent, but that's a different concern. Also, dynamic routing protocols can be slow to converge when problems occur, but fast-converging protocols such as EIGRP and OSPF wouldn't have this problem. Also, if you just have single links and no redundancy, there's nothing to converge to anyway. Static routes will work but could get cumbersome to configure and maintain as your network grows. Also, do the branch offices just need to get to the central office, or do the branches talk to each other? If so, a default route or a routing protocol might be a better option to avoid having to specify each network.

How can I get rid of broadcast storm?
Hi all Here is situation. We were trying to clone all the workstations over network in our computer lab. All workstations are set up to receive ip addresses from DHCP server, and an application server has static ip address( #.#.20.# subnet). This application server is located in our department with ip address(#.#.20.#), and DHCP server is in other building next to our department. When we were cloning all the workstations, the record showed that our department subnet ( #.#.20.# subnet) are causing broadcasting storm, so that it is screwing up another network too. So our department subnet was physically disconnected from Cat 5500. I understand that since we are cloning machines over the network from ( #.#.20.#)subnet to different subnet where all the workstations are located, this traffic has to go through a router. We are using Cat 5500. What does cloning machine have to do with broadcast storm? How can we get rid of this broadcast storm? If more explanations are needed, I will be more than happy to provide. I will appreciate your help. Thanks in advance. __ Do You Yahoo!? Yahoo!

Are they going to take any ip addresses as long as they are private ip addresses, such as 10.#.#.#? Besides that, does he still need dsl modem? or no need any more? --- Chuck Larrieu [EMAIL PROTECTED] wrote: All your friend needs is a hub or a switch, and of course a nic in each pc. Plug the ethernet port of the dsl router into the hub. Plug the pc's into the hub. Set the pc's default gateway to the ip address of the dsl router I do that here at home. Some businesses do it that way for their entire company.

Switches and VLANs
hi olzak! I have a question. How can a pc in VLan 2 reach to a pc in Vlan 3 without hitting a router? As far as I know, router would interconnect different Vlans.(in your example, Vlan 2 and Vlan3). I mean, is it possible not to use a router to connect different Vlans, because it can be done using Multi-Vlan function on 2900XL version? I will appreciate your reply. jeongwoo __ Do You Yahoo!?

HI all I have a question. Cisco recommends that there be one-to-one relationship between ip subnets and Vlans. When the number of devices on a Vlan exceeds the number of host ip addresses per configured subnet, more than one subnet can exit on a Vlan.

dhcp on router?
hi! all. I thought that the router only forwards the DHCP request from clients to DHCP server. So, can router dynamically allocate ip addresses for DHCP requesting clients without reaching to DHCP server? Then the router also should have same stack of all ip addresses on its memory.. How does router get all ip addresses? Does it receive from DHCP server? If the router serves ip addresses, what is the benefit of it? Could somebody answer this?

It usually the last byte of the default that's used to supernet so 172.37.2.56/8 could be a supernet but I doubt it that it would be used I'm still a bit confused with that 172.37.2.56/8 to /20 because the class B default is /16 (255.255.0.0). So if it was supernetting then it would be something like /14 but then it would say in the question otherwise it can be a class B with default subnet mask but still with 14 bits borrowed to make 255.255.255.252 wich you can use in WAN links so you don't lose a lot of hosts but then you have to use a Routing Protocol that can handle variable subnet masks) Hope this will cleared the confusion Koen -Original Message----- From: jeongwoo park [mailto:[EMAIL PROTECTED]] Sent: Friday, 14 July 2000 15:08 To: KoenBeth Subject: RE: Tcp/ip question hi Koen What i meant by class B, subnet mask without default, 12 extended bit was that 172.37.2.56/20 is class B and it can be a form that 172.37.2.56/8 has been subnetted to 172.37.2.56/20 by increasing bits from /8 to /20 (so, 12 bits was borrowed).
