Load balancing on Cisco ASA over VPN

[vaibhav58]

Hi Guys,

I have a site to site VPN between two sites on cisco asa , both have dual ISP and vpn has been created on both ISP and one of them server as a backup for other.

I want to know if i can use both the vpn link together , say just like link aggregation i.e. use both link for my traffic to the other site.

This is so i can have a bigger pipe for my traffic . Is it possible?

Thanks in advance.

Regards

Theoretically, you could use ECMP if you have 2 unique tunnels between the sites, each with its own outside interface (ISP). Having 2 equal cost routes will send traffic through both tunnels towards the other end. I have never seen this being used though.
