Seeking BGP Verification

[jasonwinters]

The company I work for will be purchasing a redundant internet connection, as they have been moving services to the cloud.

The company has services in AWS which are accessed via duel IPSEC VPN tunnels for redundancy.

With the addition of an additional Internet connection I was hoping some experienced eyes could have a look over my proposed BGP config to verify it will fit the bill.

A diagram of the connectivity is attached, essentially we will have 2 internet connections with 2 IPSEC tunnels using BGP to AWS over each Internet link.
