ESPECIALLY if you are an ISP (i.e. 100s if not 1000s of people are PAYING you for reliable access), you need to be running BGP or a comparable external routing protocol with at least two different backbone providers. All other solutions will leave your customers in 'limbo' while waiting for you to drive to the office or remote access in and 'switch stuff over to the backup'. Your customers become the christmas tree lights "when one goes out, they all go out" BGP, assuming you have picked decent upstream providers, allows you to route your IP blocks from both upstream ISPs across both ISP's networks. Outages result in (almost) immediate routing updates - your users don't notice much at all assuming proper network design on your part. - Tony --- [This E-mail was scanned for viruses by http://www.intouchmi.com] To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
