I have VM-100. Running around 50 tunnel to different sites and 4 AWS tunnels.
All tunnels running bgp and is all good. When i export 10.48.0.0/12 to aws via bgp,number of routes go above 100 ,aws doesnt
accept more than 100 routes and bgp to aws drops.I cant advertise defaull route as AWS need to send traffic to internet not to firewall only which happens with default route advertisement.
How can I summarize 10.48.x.x subnets learned via bgp from different tunnels and send to aws only.

I'm not sure I am picturing the toplogy correctly. are you looking for these instructions on how to create and use aggregate routes in BGP?
Or are you hitting this issue, where you can't advertise the aggregate up to the tunnel peer because it also has a contributing route for the aggregate on their side?
