Re: Access server 2511 Reverse Telnet [7:73656]
Hi Wallis. You have to use a crossover cable, not the normal straight through. If you have the one with octal cables, you can use a RJ45-RJ45 connector and then another crossover cable.

Re: ISP OSPF Design [7:65316]
Hi. Usually ISPs use Integrated IS-IS for their IGP (at least the ones I've dealt with). IS-IS can deal better with large flat networks and has better convergence characteristics (milliseconds vs. 6-46s). That said, you could certainly use OSPF as your IGP. On CCO there is a document called "ISP Design Fundamentals" which could help here (too lazy to look it up now...)

BGP dampening [7:65086]
Hi! Can someone point me to a document which explains what happens with a prefix that is dampened if it's distributed via two providers. Will only the penalized route dampened, that is will we still have connectivity if one link is flapping. I think so, but I'd like to have some confirmation for that.

Re: What is QIP? [7:64819]
Hi. Quite offtopic, but anyway. Lucent VitalQIP is an enterprise / carrier class IP administration system offering e.g. DNS and DHCP services on a central platform. Quite good, in use by many large companies (I've heard of installations scaling up to 4 million Objects (IPs) in production). Currently I'm implementing a QIP based installation for a large german transportation company (think trains, think many employees). If you want more information on it, don't hesitate to contact me.

RE: Is there any switch capable of assigning IP addres [7:58230]
Hi. I'd simply use secured switchports fixed to one MAC address and a DHCP server which gives out IP addresses based on MAC address. You could also use static ARP entries (this would need to be done to all the machines on the network though). But I can not really see a scalable Solution. 100 stations? Error prone and a maintenance nightmare. Perhaps someone has a more elegant solution? Regards, Oliver Aaron Ajello sagte: > This might sound silly, but could you use a cat 5000 with an RSM or a > 6000 with an MSM?.

This actually creates no loop. The issue you have here is that all traffic forwarded on VLAN 7 on SW A gets forwarded to VLAN 8 and vice versa. So you see the MAC addresses on VLAN 8 also on VLAN 7 which could probably confuse the switch. It did never occur to me that someone might be doing that, so I can not tell if this really causes problems. But it's definately no STP loop (especially with PVST etc.).

reading BGP4 table size via SNMP [7:55340]
Hello. Does anybody know how I could read the BGP4 table size via SNMP from a Cisco router (7200VXR and 7603)? The only suggestion I've found so far is to walk the table and count.

Hello Puro. The UFM will still pass traffic during the burning of firmware. However, be aware that it can always go wrong.

RE: need help !!! [7:49315]
Yes, this is OT, but nonetheless: Mark W. Odette II sagte: > Totally off topic, but out of curiosity, does anyone ever refer to Cisco > or Cisco Systems in "Other" forums as Ci$co or Ci$co $ystems? I only know this spelling with a company from Redmond, WA > > Just a pondering thought... after all everyone seems to agree that Cisco > charges the most for their products in comparison to competitors, and > that the competitors seem to have Internetwork Devices that are far > superior in capabilities or performance in many cases compared to > Cisco's gear. Who really agrees on that? There are many cases where I've seen that competitor's devices seem to be much cheaper, but are not in the end. Many bought cheaper products which were working for the anticipated environment. Later, some change in the network was needed (as is constantly the case in every medium-to-large network). The device couldn't adapt to the new environment (be it a new network protocol or a new interface type). With Cisco, you often can upgrade the devices to a very high degree (there are e.g. still many long gone Cisco 4000's in use. Even with IOS 12.1. And another point, which Cisco hammers on in its sales trainings: Cisco delivers an end-to-end solution. Sure, you can buy a better-performing Juniper M20 for less, but your network administrators will have to know exactly one environment if they buy a GSR 12k. It has the same look & feel as a 2500. And having worked with TAC multiple times, I have to say that I'm pleased to have seen mostly competent technicians there. Kudos, I know how hard such a job can be. Disclaimer: I'm not related to Cisco in any way except being CCNP and working very much with Cisco equipment (and still liking it). Sure, Cisco can improve in many areas. But I think it will -- or will fold sooner or later. Then we can talk about it again.
