Here's a question I can't seem to answer. I came up with a scenario in my head, and now I can't find a solution.
Example: I have a dual homed network via BGP. I have ISP 1 and they give me 209.21.220.1/20 for use, and ISP gives me 199.33.23.1/21. Say I use the 209.x.x.x for my web servers, mail server, etc, and advertise that back out to the Internet via ISP 1 (the ISP that assigned me the block) and in DNS. I'm assuming ISP 2 will not advertise that block for me, as it's ISP 1's block. So, now the whole world knows to get to me via ISP 1. Then let's say ISP 1 goes down, how would the world know how to get to me, if they only knew how to get to me Via ISP 1 and it's IP's? -- RFC 1149 Compliant Get in my head: http://sar.dynu.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=43163&t=43163 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
