by K.Graham 29 Mar '01

29 Mar '01

Just a quick question. I am trying to find some documentation on Alteon switches. In particular the WebOS. Of particular interest are command references, troubleshooting, and configuration. If anyone can give me pointers to information it would be appreciated. Please reply off line so we do not spam the list. Kim Graham

FW: Next Hop Attribute
by Charles Smith 29 Mar '01

29 Mar '01

re-posted for broader audience: My apologies if this has been discussed recently... Is there a collective wisdom as to why the BGP RFC makes the statements that it does about the BGP next hop attribute? Specifically: (From RFC 1771): "A BGP speaker must never advertise an address of a peer to that peer as a NEXT_HOP, for a route that the speaker is originating. A BGP speaker must never install a route with itself as the next hop. When a BGP speaker advertises the route to a BGP speaker located in its own autonomous system, the advertising speaker shall not modify the NEXT_HOP attribute associated with the route. When a BGP speaker receives the route via an internal link, it may forward packets to the NEXT_HOP address if the address contained in the attribute is on a common subnet with the local and remote BGP speakers." At routers that have EBGP session injecting routes into its own AS on Cisco routers we set the next-hop-self attribute to eliminate synchronization issues, but I'm curious as to why the RFC made these requirements in the first place? Thank you for any brain cycles spent on this. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

RE: Content Injection Appliance
by Irwin Lazar 29 Mar '01

29 Mar '01

I think that you are referring to the Nortel/Alteon product line. http://www.nortelnetworks.com/solutions/mahs/hosting/idc/net_host.html These devices have the potential to make the Internet look a lot more like cable delivery networks - e.g. Time Warner Cable forces Disney to pay to allow TWC's cable modem customers to access Disney web content. UUNET strikes an agreement with CNN that blocks access to FOX, NBC and other news sites, etc. It also could kill the web banner advertising industry as these devices allow ISPs to replace banner ads on a web site with ads inserted by the ISP. Even worse, web surfers might be forced to watch a 30 second commercial for every ten minutes that they surf. The privacy issues alone could generate enough discussion to write a book (or two). It almost looks as if we'll move to a model where free, unimpeded access to the net is going to cost a whole lot more than $21.95 per month. Irwin -----Original Message----- From: shane [mailto:shane@bratnet.net] Sent: Thursday, March 29, 2001 2:43 AM To: nanog(a)merit.edu Subject: Content Injection Appliance I need someones help, I saw a product at ISPCON Fall in CA. And the product allowed me to have it operate on my core routers and watch web traffic and allow me to "Inject" a "pop-up add" or a service anouncement. I have been searching my ISPCON "stuff" I collected and I can't find it, and it is driving me crazy. What I want to do is set up this box to watch web traffic, and when a new user logs in it checks to see "for example" if he has new mail on our mail-server, and pop-up a little window on his/her screen alerting them about this. But I don't want to make the user be required to use our home page as the start page. Can anyone tell me the name of this product, I am already aware of FrontPorch and their product would work, but they require me to allow them to to advertising to my customers, I don't want that. shane brath TDS.NET Internet Services shane(a)bratnet.net

RADIUS info for traveling users ...
by Mohan Sundar 29 Mar '01

29 Mar '01

Hi, A Service Provider, having several POPs, I presume will be using at least one RADIUS server that is associated to each POP, and are usually colocated at the POP, along with the RAS, aggregation and other IP service devices. And the IP address assigned for a subscriber dialing up from one location is assigned by the corresponding RADIUS server, after authentication. If this is the case, how is this subscriber provided service like internet connectivity, when he travels to another part of US? Will the RADIUS server info be available to all the POPs of the Service Provider? How are the current ISPs doing this? To take it further, when policies are associated with this subscriber that are based on IP address, how is that handled when the subscriber travels? Your input on this will be greatly appreciated. thanks. Mohan __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
