Title: I have been tasked with getting traffic from AWS, to a colo, and out through a private link to a third party.  I am a bit out of my depth here. How can I quickly learn to design and configure networks? I learned the basics of networking in university, and can work my way around all of the cloud provider networking primitives.<p>However, this seems like a different beast.  I need to learn about cross-connects, DHCP, ARP, BGP&#x2F;ASNs, firewalls, etc.  The reason I have found this difficult so far is that educational content I am discovering falls roughly into two categories:
1) Network programming, i.e how to use Unix sockets and system calls
2) Virtual networking, i.e AWS&#x2F;GCP networking primitives which are useful and important but I believe I need to go further.<p>I am not exactly sure where to start and am hoping for some direction.  A Cisco certification course?  An MIT OCW networking 101 course?  I have limited time and am looking to become simply proficient and provisioning and configuring to get my team unblocked.<p>Thank you so much in advance.
