Our router is running simple bgp. "one BGP router, two upstreams (each 100M
from ISP A and ISP B)
We are getting full feeds tables from them

We discover the routes is going to ISP A only even the bandwidth 100M is

Can we set the weight to change to ISP B to use ISP B as preference routes?

Can the following configuration work?
What suggest to this weight no. too?

 neighbor description ISP B
 neighbor remote-as 111
 neighbor weight 2000

If this works, how is ISP B upstream connection is down?

Can it still be failover to ISP A automatically?

If it won't work, Do you have any suggestion?

Thank you for your help
