Re: ONE or TWO PIXs
Uh, what are you thinking? youre about to put as 10K box on a 64k hookup. screw the pix. pix are awefull. you really ought to invest in a better connection if i were you i would do that, and use something like a linux box or obenbsd box as your firewall. either that or a cheap router doing NAT/PAT, and use the rest of your moolah to get a nicer connection brought in. if you have two connections, you should use a router anyway, NOT a pix. a good router can do just about anything the pix can do anyway. they are MUCH better for reduncany as well, dseepending on how you look at it. fmxiao wrote: > All kindly guys, I need some help or suggestion > > Our company has two lines connecting to Internet, one is only 64K for DNS or > mail server, > the other is for WWW service.

Re: Question on the meaning of "tunneling" [7:6136]
ok. well my own personal idea of a tunnel is a thing that ecapsulates traffic to make it transparent to the underlying network, or vice-versa... the VL does not meet my own definition, but it is an alternate path that the traffic can take. In reality, the traffic is ROUTED along the path that you need to take to get to the opposite endpoint.

Re: how to track down unused ports on a switch [7:9213]
OK. THIS IS OUT OF THE QUESTION. I want to let everyone on this list know, that after a post I made to this group today, the second post in this thread, i was pulled aside by my manager. The email, which i appologized for, was directed at luke, member of groupstudy. in it, I jokingly had called him a "brainless peckerhead". I appologize if this offended him, im sure he's a nice guy and all, but he recomended a solution which would take thirty days to complete, I AM NOT RECANTING MY APPOLOGY. ..However, my manager printed me an email from someone who fancied himself more professional than I. The email from [EMAIL PROTECTED] said, " I just thought that someone might like to see how your engineers are representing your comany publicy", and, then stated how easy it was to find my company's webpage, with the information contained in my signature file. Steve Brokaw, MCSE, CCDA, CCNP, had taken it uppon himself to forward the email thread to my CEO Ken Mckinnon. Steve had titled the email "A rude Planetary Networks employee" At that point, copious amounts of sh*t began flowing downhill at supersonic speeds. This, I do not think was deserved. I Post constructively to this group CONSTANTLY, as i have for almost a year now. I do my best to help you people out. I have even put labs together on my own time, with my own equipment, to simulate problems and scenarios described by members of this group. ..Now, this email was in NO WAY directed at steve. I have not seen enough posts from him on this group to warrant his policing of it. Steven was kind enough to sign HIS message Steve Brokaw, MCSE, CCDA, CCNP Sr. Network Engineer 817-233-8075 cell How nice of him. He took something that should have been addressed to the group, and got up close and personal with my CEO. "this is how engineers are representing your company"? Are you serious? Steve, are you trying to get me fired? Do you guys who post on this list regularly want to have to worry about crap like this? Do you want to worry that if you say something that pisses someone off will come down on you like a jackhammer from your employer? Are we babies? I thought we stopped tattling on each other years ago. ESPECIALLY anyone old enough or professional enought to be titled "Sr. Network Engineer" but then again, steve was the only contact provided, im not going to say anything offensinve, and will stop right here before i get in any more trouble. Im not going to sign any more of my posts. Of course, you could always go look at my email address and find my domainname. I called Steve today. I asked him why he had done this, his response was "you were being a jerk"... And he hung up. HOW PROFESSIONAL. You wasnt disrespectful? how's being hung up on. If anyone thinks someone else is at fault, YOU TAKE IT UP WITH THEM. NOT MOMMY OR DADDY. This is not kindergarten. We are all engineers, we should all be friends, and work together, we shouldnt be getting each other in trouble. Steve, at least I realize that i was at fault here, and appologized, but i think that you have done is absolutely out of the question. What goes around comes around, and i hope that one day, you learn your lessons the same way I get to.

Re: Wanna Be a CCIE? Try This One [7:6076]
well, since C and D are in the same area they have the tame topology DB. they KNOW the best route to each other and are going to use it. the tunnel idea is kinda stupid. first let me ask why you would want traffic between two directly connected routers to NOT use that link? ...But anyway, i would suggest policy routing in this case, or if there is a large traffic volume (too much for routers C and D to process switch, make static routes. other options include putting C and D in their own areas, and making each a stub, and get rid of that link between C and D. that would be the best idea... play with plath costs, and you might try a virtual link as well between C and D, but break glass only in case of emergency, if you know what i mean =P -Peter - Original Message - From: "Kevin Schwantz" To: Sent: Tuesday, May 29, 2001 10:03 AM Subject: Re: Wanna Be a CCIE?

Absolutely, but he has traffic going from one router to another, it's not ever exiting the system. ...why would you want to break up an AS that small into two seperate private ASes? besides... the OSPF routes are going to take precedence, not that the admin dist. cant be changed, but ospf is 120, and BGP int routes are 200 (right?) - Original Message - From: "W.

I think BGP is completely unecessary in this case.YES, splitting it into two ASes ans using eBGP would work (well), but i really think that modifying the path cost would be the right solution. remember that i never said eBGP wouldnt work. the initial discussion was about using BGP to do this in a SINGLE AS. ...don't get all in a tizzy, i recognize that you have a good idea.
