RE: IPSec Latency [7:15874]
The maximum delay for keepalives really depend on your phase one and phase two lifetimes. And if you have an idle timer set for your tunnels and whatever that value may be. Keepalives are mostly supported by your router or vpn box. I haven't ran across a client that supported keepalives. Although there may be one. It only takes one direct for keepalives to keep the tunnel up. As for documentation, I haven't seen any. I have been working with IPSEC for a little over a year now and I have yet to see alot of vender specific documentation, only because IPSEC is still new and being tweaked. -Original Message- From: Cisco Chic [mailto:[EMAIL PROTECTED]] Sent: Monday, August 13, 2001 10:32 AM To: [EMAIL PROTECTED] Subject: IPSec Latency [7:15874] Hi All, I was wondering if anyone has any information or sites which talk about how to tweak (if this can be done) IPSec tunnls (via keepalives) from a dial up client to a VPN5008? We have a latency of around 800 milliseconds on a network and we are trying to determine what the maximum delay can be in the network to keep the tunnel up via keepalives. How long can the delay be for the keepalives and who sends the keepalives or are the keepalives sent in both directions via remote dial up access. (we are using static routes) I know that a keepalive protocol is used by L2TP in order to allow it to distinguish between a tunnel outage and prolonged periods of tunnel inactivity. We are trying to find out if this can be done for IPSec. We have a open case with cisco tac currently to get more details and have been looking at third party web sites and RFCs. Can't find anything about latency but have found performance issues concerning bw, memory etc. Any information or sites you can direct me to would be great. Thanks!! __ Do You Yahoo!?

I know Rita, and I regarded this as a legitimate request for information. There's a delicate line, I will admit, about information and advertisement. I don't think there was anything wrong with my posting a response to some reviews of my book, and adding some perspective. If it was a request for info why the link to the course URL? It is said that the cook is involved with making a BLT but the pig is committed. There is nothing wrong with doing business here, but seems like Rita is already teaching an on-line course so why the research. Looking at the link, Rita seems more than qualified to teach a course in entry level tcp/ip, yet doesn't know the feasibility of on-line learning Howard lets look at it this way: What do you all think about learning by reading from a book. I would like to get everybody's thoughts, OH by the way here is my book Designing Addressing Architectures for Routing and Switching ISBN: 1578700604. You must of thought it was a good idea or you wouldn't have written it. There you go a plug for a good book. Then Rita sends back a reply refuting my opinion, so I guess I don't feel that way. Then you do the same thing saying you can learn on-line but you don't like a classroom setting. I don't like an on-line setting or classroom setting that is still my opinion. so different people do have different opinions. Would much rather learn by teaching oneself (guess that is why we home school), also have taught adults and agree that I learn when in class teaching others. There are, again in my opinion, three ways to learn 1. repetition/memorization 2. facilitation 3. mentoring generally children need mostly 1 and some 2 generally adults need mostly 3 and some 2 I don't see where an on-line course can provide much real mentoring. The simple type 1 learning I feel on-line courses provide can be done by reading either Perlman or Comer which are listed in the recommended texts yourself. Rita, Howard do you have a mentor, are you mentoring anyone I can say yes to both. Even a boor like me could learn something from you Howard if you mentored me but you have to guarantee a win on Jeopardy with Alex. From a cash flow perspective on-line learning is great and much success to y'all??? The "good advertisement" and the "on-line learning" issues are seperate, and Rita, I apologize for being flip about your e-mail. If you are still here do either of you know Don Personally don't think you can learn anything new on-line. For some people, it may be the only option, even at the beginning. They may be in isolated locations, can't go to regular classes, etc. Classroom training is probably best for many people, although I tend not to learn well as a student in a formal class (I teach them well and learn when I teach) On-line learning is good for people finishing degrees not for entry level. Or in staying abreast of technology in general. Most of the real work of the IETF is done via mailing lists. Yeah but if you are on the IETF mailing list a lot is implied, start sending those e-mails to someone who doesn't even have e-mail and see if they are up to speed in no time :) Is this part of a degree program.

You actually never know what a Guy knows. I have an ex-coworker that is a CCIE. He got recruited by Xedia Corp 3 years ago.He had to learn there routers and technology. And also he works mostly with ISP's now. His Cisco knowledge has slipped and the first to go is basic concepts. He still knows Cisco, but to someone who works with it everyday he might seem like a dumb CCIE. Now if he comes back to the Cisco side of the track, yeah he will get job offers and a good position. But to the common Engineer ready to critique him, he will seem quite a bit of a Cisco poser. Derek S.

I faxed a copy of the business card he gave me (homemade BTW) to someone in the CCIE program at Cisco. She told me the card is bogus and that she would send the card to the Cisco lawyers. That was three months ago and this person is STILL working on site there. What do you people think I should do now? Send e-mail to the persons that are contracting him there? He is charging a very high bill rate. The people he is working don't have enough knowledge to confirm his credentials. Should I let this go?

RE: PRI vs T1
Actually they are both one and the same. The coding in the way the T1 is setup at the CO makes it viable to be used as a T1. Both provides 1.544mbs bandwidth.

RE: PRI vs T1
And that is correct. T1 is basically a physical standard for a Pipe. PRI is basically a logical standard for a pipe. The framing and line coding are the same. Derek S.

RE: Connecting Switches, hubs..
Traffic would overflow into both vlans. You would have traffic from VLan 100 flowing in 200 and vice versa. Only if you uses somekind of trunking will the packets get tagged with somekind of header so something like this would be disallowed. But to answer the question, that packets will get dropped after it reaches the vlan and find out it cannot be routed to any port. Derek S.

It only works in a completly switched network. Hubs do not run STP, hence the switch does not get BDPU's from the hub and does not recognize the non-STP connected ports in order to put the port into to a mode such as blocking mode. correct. That said, let's say you do have 2 switch ports (12) connected to a same hub. A broadcast occurs, which comes in on ports 12, but since a switched port does not return traffic to the source port, the broadcasts coming in on ports 12 will not get re-broadcasted back onto themselves... but broadcasts going out port 1 will still goto port 2 (which isn't itself), and vice versa.

Now my next question is: Do I now have an aggregate bandwidth of 20mbs? Actually STP is important in your example. if you have a switch with two ports connected to a hub, say ports 1 and 5. A broadcast sent to port 5, will come back into the switch on port 1. Since switches forward broadcasts, it will go back out port 5, and back in port 1, and this will continue infinitly if STP is not enabled. In multilayer switching networks, you can actually have your broadcasts magnified, and things can get REAL ugly. Brian TIA!
