BGP prefix announcement issue
Posted on 2013-05-16
I currently have the following setup:
2 independent ISP's (ISPA and ISPB)
I have 2 /24's each able to be advertised to each ISP
I have 2 routers. R1 is connected to ISPA and R2 is connected to ISPB. R1 and R2 are connected to each other.
On R1, I have static routes to null0 for each /24 along with the bgp config. Each /24 is working fine. However, when I add the static routes to null0 on the 2nd router, connectivity gets lost on the first router. If I remove the static routes to null0 on the 2nd router, things start to work properly again.
Any idea why this is?
