Hello, > This is not easy to answer without all the details. But for sure there are cluster running with BGP in the field just fine. Out of curiosity, is there someone here that has his Ceph cluster running with BGP in production? As far as I remember, here at croit with multiple hundred supported clusters, we never encountered a BGP deployment in the field. It's always just the theoretical or testing where we hear from BGP. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@xxxxxxxx Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx On Tue, 6 Jul 2021 at 07:11, Stefan Kooman <stefan@xxxxxx> wrote: > On 7/5/21 6:26 PM, German Anders wrote: > > Hi All, > > > > I have an already created and functional ceph cluster (latest > luminous > > release) with two networks one for the public (layer 2+3) and the other > for > > the cluster, the public one uses VLAN and its 10GbE and the other one > uses > > Infiniband with 56Gb/s, the cluster works ok.
