I have connections to 2 ISPs terminated on a single router taking full routes.
ISP A- T3 address block xx.xx.xx.xx
ISP B- 2xT1 advertises the same block
I have set the local preference to 500 for ISP A.
I have also prepended our AS for our route advertisement going out ISP B.
This works to steer traffic to ISP A for the vast majority of networks. In some cases ISPs advertise more specific route only to ISP B. This results in a relatively small number of routes pointing to ISP B. It appears that hosts in these networks cannot access our web sites. I have a client in one such network who cannot access our web site.
I tried a static for the client IP point to ISP A with no luck. Any thoughts would be appreciated.
