BGP & Routing -- Noob Asking Advice

Hello,

I hope it is okay to ask here because I am not sure where else to ask...

So here's the basics.

We have an ASN, several IP blocks (v6 + v4) etc.

We have a BGP server setup on a server with BIRD that is working fine and broadcasting blocks to upstreams.

Now the question is:

Do we need to make a router or can we install routing software onto the same BGP server and how to add the blocks to it so they can be mounted to the server?

Before we had BGP hosted but the routing was handled by someone else and I have no idea how they set it up, assumable was a Cisco all in one type setup.

Now that everything is in-house, I am wondering other than BGP, what next step is there to have like from them we had before a gateway, netmask, and all. If I mount them on same network BGP is running on like they were before and use the BGP server IP as gateway, does this work? Or how?

​

Sorry for the noob questions here. Just trying to get this up and running and really don't wanna go spend 1000s on some all in one solution when it seems a simple server running this connected to switch is fine.

Pretty much my assumption is that there needs to be a router that is capable of handling external addresses and not some normal NAT based router there, or router software. Just not sure what to use.

​

Thanks.
