I have successfully added a *ton* of address families in my build. I will PR it, but we also have found an error. The error that we have found is an FRR error at this link here.

Once I finish up and verifying all of my work I will be putting a PR this week to add address families inside of BGP. Please note, they will be we'll add more over time. But they do seemingly work otherwise.

FRR coder Donald Sharp kicked ass and fixed it here...

Once this PR is into FRR then we should be able to put in my PR for BGP.

I put in a PR for this:

We still have problems though as the bug is still not fixed yet in FRR. I checked on this bug and unfortunately the PR that was supposed to fix it did not. I'm still bugging Donald Sharp on it. When it is fixed we'll merge.
