I've got a direct connect for public AWS space. I used this https://ip-ranges.amazonaws.com/ip-ranges.json provided by AWS support so I could filter the over 2000 routes, we're only going to use S3 in the US for now. Unfortunately the prefixes in my route map are summarized (as they show in the link) but actually many come through as /24. I went from 20 prefixes summarized to 600. I don't want to advertise 600 additional routes into my network.
We're redistributing from BGP to EIGRP.
Options: 1) I could manually summarize these routes on an interface "ip summary address eigrp 1 x.x.x.x y.y.y.y" (I think is the correct syntax) but we're network engineers and we don't like static or manual things.
2) I could just redistribute all of them and potentially crash some of our older equipment but I like my job.
Those are the only two options I can think of off the top of my head. Are there any mechanisms of summarizing to what AWS said they're using?
example. int g0/0 ip summary-address eigrp 1 52.92.48.0/22 complete for all the below 52.95.142.0/23 54.231.232.0/21 52.218.128.0/17 54.231.0.0/17 52.219.20.0/22 52.219.24.0/21 52.219.96.0/20 52.219.120.0/22 52.95.144.0/24 52.92.16.0/20 52.219.80.0/20 52.92.32.0/22 52.219.112.0/21 54.231.160.0/19 52.92.76.0/22 52.216.0.0/15 52.95.166.0/23 52.95.168.0/24 52.92.252.0/22
