Jean-
Yeah, don't worry about people complaining.
Is this an accurate description of what you are trying to achieve?
- Have 2 different sets of prefixes that you announce. Set A via
router1/ISP1 , Set B via router2/ISP2
- If BGP to one of your ISPs goes down, start announcing those prefixes to
the other ISP. ( Example, if ISP2 goes down, start announcing prefix Set B
over ISP1 )
