Hi,
Is Free Range Routing (FRR) a viable choice for a pure BGP route reflector
for a regional ISP with ~ 35 routers? A mix of L3VPN-MPLS and BGP-EVPN
services. Full transit, plus some peering. About 5 x L3VPN instances, and
maybe 500 x EVPN-MPLS instances.
I don’t see a lot of posts of people using FRR for RR. And not a lot of
people reporting issues, so maybe it is just the perfect RR solution?
We have 8 devices running FRR for iBGP to form our DCN. 2 of those 8
devices are RR's, and the other 6 are clients.
7 of the devices are pfSense running FRR, and the other one is FreeBSD
running FRR.
All of them are running WireGuard to create the mesh with OSPF (multiple
cities around the world), and iBGP on top of OSPF.
Haven't hit any drama.
FRR in pfSense is very forgiving, because they assume many roadblocks on
your behalf. FRR on FreeBSD was a bit more work, but nothing insurmountable.
Mark.
