Hi,
There are several discussions in the past, you can read them on
https://lists.apache.org/list?users@cloudstack.apache.org:lte=1M:vxlan
Indeed, however, here is the Frr configuration we are using.
Keep in mind that you will need a modified version of modifyvxlan.sh so
that it doesn't use Multicast for your VXLAN!
The configuration below uses BGP Unnumbered on two uplink interfaces
(ens3f0np0 and ens3f1np1) where it then announces a /32 and /128 to the
upstream routers.
VXLAN traffic is carried by IPv4 in this design, but with proper modern
switch this can be IPv6 as well.
IPv6 is used in this case for all other traffic then VXLAN:
- Management
- Storage
- Ceph
- TrueNAS
- Monitoring

Good morning guys,
me again :)
We are configuring VXLAN with KVM+Cloudstack, I have read the doc from
cloudstack website, but I cannot find anything about FRR, I understand that
cloudstack does not manage FRRounting, but in any case could you please
recommend a good guide?
Kind regards
Thank you all in advance
