Our router is running simple bgp. "one BGP router, two upstreams (each
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
Can the following configuration work?
What suggest to this weight no. too?
neighbor 18.104.22.168 description ISP B
neighbor 22.214.171.124 remote-as 111
neighbor 126.96.36.199 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
I've done this for a few customers that have requested it. Some engineers
complain that advertising /24 routes dilutes the Internet routing tables,
which is true in some regards. However, this does work in many situations
to "balance" things out.
Check out my blog post that walks through this procedure:
