Subject Re: [PROPOSE] Dynamic inter VPC routing
Date Wed, 27 Jan 2016 22:54:27 GMT
Hi Abhinandan,

I'm actually looking at how to perform routing between VPC, but in our case
we still need the public interface of the VPC as it is right now.
Improvement such as BGP for  various public route would be helpfull. But,
when it come to internal traffic between VPCs, there is 2 way that I see
for now,  IPsec, and Private gateway. In both case it does not scale well
if you want to interconnect let's say 10 VPC's together. Look Like using
things like OSPF has you are proposing make lot of sense, but do you
foresee to publish OSPF traffic against a dedicated VLAN into a
PrivateGateway instead of the public interface?

I was about to propose a feature spec around this, but I did not had
success yet in a quick POC, for some reason I had issue having Quagga+OSPF
 to work between VPC thru the Privage Gateway. probably just an iptable
issue.

Looks promising...
