I have 2 trunk connections going to the core. It is going to one of our distro switches. What protocol can I use to make the second connection redundant? So it takes over if the first int fails?

Is there a way for me to do this? We have 2 trunks from our core to our distro. Instead of having both connections, I would like it to go through only 1 trunk and then use the secondary if there's a failure.

Any help is greatly appreciated.
