How to properly use 2 channels?

Question

Domain Name System

Hello!
There is Ubuntu Server 14.04 with two links and IP addresses (from one provider).
Each link issues n-Mbps.
The task is to organize a garden of several web servers on IIS with ssl.
That is, I plan to:
1. set a dns-server on these two links (a kind of Round-robin) and redirect requests by headers to local servers;
2. increase the speed of the channel using link aggregation - but what about two "white" IPs in this situation? Doesn't this idea contradict item 1?
Please help with advice.

Answer 1

1. Implement, there is no fundamental difference to work with two servers or one with several addresses.
2. Normally, without crutches, channel aggregation cannot be done, crutches are a separate issue; there are many different ones, almost all of them are crooked and depend on the situation.

Answer 2

Seriously, look aside: BGP This is at the level of the protocol and switches
. For example, mail - in one channel, web traffic - in another. It's all at the firewall level.
