We have two different Internet links from the same provider. One link is in our main site and the other is in our DR location.
Each site has different hardware, edge routers and ASA5510 firewalls. Each site is in a different public IP Address range.
So, depending on which link is used, the traffic is sourced from a different address range.
We have a connection from the main site to the DR site with 100Mbps MetroE connection.
We also have an MPLS cloud that links the Main site, DR site to all of our branches.
Main site and DR site each has a link to the MPLS cloud, each branch has a link to MPLS all are via BGP.
Currently, everyone uses the main site for Internet access, a default route is being distributed from the main site Internet router to everyone.
There is a higher AD default route in the DR site internet connection.
If the main site goes down, a higher AD default route from the DR side is distributed to everyone and they go out that way.
Is it possible to do some load sharing from any one of our sites, so that the traffic is shared equally across the two Internet links.
I have been told by my manager that this is an easy thing to do (they do not know if it is or not).
For example, we have Webex, could I make an outbound connection using both internet links to the Webex destination IP Address by per packet or per destination load sharing?
The default route being distributed to everyone will have to be across the two internet links.
