Hi
im planning setup a two sites with 2 different isp interconnected eachother
i have a /23 ip block and a ASN
Site A use ISP A With a CCR2004
Site B use ISP B with a CCR2004
and both sites are interconnected
now im want to use all the same network range /23 on both sites
if ISP fail on site A use ISP B
if ISP fail on Site B use ISP A
if interconection between both sites fail each site use the site ISP
what is the best way to approach this setup?
thanks
