Re: FRR for BGP route reflectors?

Hi Tom!

We are using FRRouting on Linux VMs as dedicated BGP route reflectors for AFs vpnv4, vpnv6 and evpn.
Having around 1000 RR clients connected with a handful of L3VPN and a few dozen EVPN instances.
We don't keep the full routing table on them, but that should cause no problem, just throw a bit more memory onto the 
VMs.
BGP works like a charm on FRRouting and is also pretty good on supporting recent BGP features.
We can absolutely recommend it.

As a sidenote: IGPs at FRRouting seem to get a bit less love, so don't be too sophisticated there...

BR,
