Nimbostratusrunning Active-Active with BGP
Hi, i am scratching my head as to how this works We have 2 F5 1600's running active-standby using 2 different internet paths with BGP advertisment of eg 192.168.5.0/24 on both using LocPrf of 100(active) and 70(standby) i need to modify to Active-Active. i have created a traffic group and told a VIP of eg 192.168.5.10 to use it but i am unsure as to how BGP works with this. as you can imagine i have Asymetric routing as it goes out Box B and tries to come back Box A
Idealy the nonspecific BGP route of 192.168.5.0/24 would stay on box A and the new more specific route of 192.168.5.10 would have been generated and advertised with a higher LocPrf for box B
Can anyone shed some light on this. cheers

Most ISPs won't accept BGP routes for anything more specific than a /24 so you will probably have problems outside your control even if you do get the LTM to do what you want.
In any case you probably want to follow this:

electroboard_13i followed this guide, thanks, but i can now see that BGP is suppressing my route. is there a way to force to not suppress route

Our ISP have said they will advertise whatever i give them. i have made the "redistribute kernel" change but the route that is advertised is a summary and not the specific routes. what am i missing
