Hybrid Routing
Similar to the "All Campus Routing" above, this configuration brings all of the Cornell campus IP space (10-space and public addresses) over the Direct Connect. Where it differs is in the individual subnet route tables:
- Private Subnets: AWS subnets without direct Internet access should use a route table that includes all propagated routes from the Direct Connect (includes campus 10-space and public space).
- Public Subnets: AWS subnets with direct Internet access (IGW) should use a route table that disables route propagation from Direct Connect and only includes references to campus 10-space addresses.
Can Cornell AWS accounts configured to use a VPN connection be upgraded to use the DC?
