Good day=20
I have a question from a customer point of view. We currently have a multi=
-site WAN with all our Internet connectivity at one site consisting of 3 IS=
P type connections, full BGP, including our own ASN with IPv4 and v6 addres=
sing space. All up and running.
I am now looking to add Internet connectivity from a second site on our WAN=
for fail over in the event of a site 1 failure. My initial thoughts are t=
owards another full BGP session at site 2, and perhaps something like Cisco=
's Global Site Selector, or F5's GTM to direct traffic.
I'm thinking of phasing this in over a couple of years since the "server" f=
olks will not have full hot fail-over at that site for that period. Of cou=
rse, in a failure situation, the site will be expected to be live and opera=
tional immediately.
Any suggestions on where I should start looking ? Any good white papers or=
case studies you have seen? And technologies we should look at or stay aw=
ay from ?
Thanks=20
