Hello guys,
I run a WISP network distributed on two cities with multi-backhauls in every city, the network is running using a static route for now and it’s getting difficult day by day to manage the network.
So, any advice on which routing protocol should I use?
Hello
I’m not a WISP, but I’ll ask you a question that others will probably ask. How big is your network? I’m assuming that your clients will just have a default route to your gateways. So no dynamic routing there.
I’m running a small 3-site MAN spread across two cities also and I find that ospf through L2TP tunnels works fine for me. All three sites have wired internet access.

Use OSPF.
Your other choices are:
BGP - big and complicated, and is mostly intended for exterior routing to/from the Internet. There are some creative ways to use it as an IGP, but they are not “usual” uses of the protocol.
RIP - only useful in small networks with a mostly stable topology / as a simple PE-CE interface protocol. RIP is chatty. It’s slow to converge. It can’t route based on any kind of metric other than just the number of hops. I usually tell my junior engineers there’s only two things they need to know about RIP: rip. sucks.
That’s it for the IPv4 routing protocols in ROS.
Getting started, you should just use a flat backbone area (area zero) and work up from there if your network demands it. Be sure to put a loopback IP on every single router and start using those loopback IPs as the official IP of the router for everything. (polling, management, source for things like RADIUS, etc)
Thank you for the advice my network is still relatively small but growing fast and I use PPPoE as authentication method at the end user device.
I was confused between BGP and OSPF but when I got your advice I’m definitely going with OSPF also MikroTik Wiki says about BGP: " If you just need to enable dynamic routing in your network, consider OSPF instead.".
