Re: BGP question [7:4973]
Greetings All I think the context of some of the conversation is missing. BGP can handle any class of address, and in fact the BGP being run on the net at present (BGP4) is classless. The whole reason for CIDR was that it was intended to shrink the size of the BGP routing tables. SO them saying BGP will only work with class C is totally bogus! BUT Any ISP running BGP will implement a BGP policy, a hopefully uniform way in which they do BGP routing and handle BGP peering with their customers. There may be rules they have set up regarding how they do BGP, and you may be asking for something outside of the capabilities of their Policy. That doesn't mean BGP can't do it, it means they do not do that. As for your having a class A address. Who do you work for? There are only 127 class A addresses, mopst belonging to ISPs or the Government, or Reserved. I can think of one compnay who has a Class A, HP, they have the 15.0.0.0 network. However if you have a RFC1918 Class A that you're using that's a whole different story. What is your address range, and which ISP told you they couldn't handle class A addresses?

RE: BGP question [7:4973]
not really true , some isp run BGP just to facilitate troubleshooting by viewing at the BGP status . If you only have one link to the isp YOU can still RUN bgp with no routes from the isp and you in turn still need to run a default route to them the BGP is just for troubleshooting purposes regards, suaveguru --- Fenech, William J wrote: You're absolutely rightwith only one connection to your ISP, all you are doing by running BGP is using up your Router's memory and CPU resources.

Re: BGP question [7:4973]
If my ISP told me that, I wouldn't believe another thing they had to say. BGPv4 supports CIDR and Classful addressing. It will advertise whatever address range you tell it to, with whatever mask you provide. Perhaps the ISP was really talking about their own policies, with regard to address space that they provide their customers. They certainly weren't referring to any limitations of BGP. - Original Message - From: Rizzo Damian To: Sent: Friday, May 18, 2001 9:38 AM Subject: BGP question [7:4973] Hey folks, I have a quick question regarding BGP.

Hmm... I would venture to say this fellow is not all that up on BGP either. We have an entire class B running in BGP. The only thing this fellow could be remotely referring to, is the MAX hop command on EBGP that allows only up to 255 hops to connect to an external BGP neighbor. http://www.cisco.com/univercd/cc/td/doc/cisintwk/ics/icsbgp4.htm#41454 The syntax this link does not explain is the hop count limit... # Router BGP # Neighbor ebgp-multihop All the best Phil - Original Message - From: Rizzo Damian To: Sent: Friday, May 18, 2001 9:38 AM Subject: BGP question [7:4973] Hey folks, I have a quick question regarding BGP.

Re: BGP question [7:4973]
The question I have is: is the class A address space you're using on your LAN private? (10/8,192.168/16,etc)? Perhaps the tech was explaining why he would not route your space because it is prohibited per RFC 1918. In other words, if you have numbered your network with the 10/8 network space, your ISP will not (re: SHOULD NOT) allow you to announce that space to them. But if you have a legitimate IP space that has been swip'd to you from your provider or ARIN, then your provider should announce that for you. brent On 18/05/01 11:36 -0400, Circusnuts wrote: Hmm...

Re: BGP question [7:4973]
They may be assuming that you will advertise a small block of the /8 space (say a /24 or /23 etc) which likely be filtered by various providers. Small advertisements out of the class C space would not suffer similarily. Pete *** REPLY SEPARATOR *** On 5/18/2001 at 9:38 AM Rizzo Damian wrote: Hey folks, I have a quick question regarding BGP.
