If your external router don't support ecmp static route to reach multiple proxmox nodes,
you can setup an HA floating vip on proxmox nodes with vrrp
If your external router doesn't support 'ECMP static routes' to reach multiple
{pve} nodes, you can setup an HA floating vip on proxmox nodes by using the
Virtual Router Redundancy Protocol (VRRP).
In this example, we will setup an floating 192.168.0.10 ip on node1 and node2.
Node1 is the primary and failover to node2 in case of failure.
In this example, we will setup an floating 192.168.0.10 IP on node1 and node2.
Node1 is the primary with failover to node2 in case of outage.
This setup need vrrpd package (apt install vrrpd).
This setup currently needs 'vrrpd' package (`apt install vrrpd`).
#TODO : It should be possible to do it with frr directly with last version.

Route Reflectors
^^^^^^^^^^^^^^^^
If you have a lot of proxmox nodes, or multiple proxmox clusters,
maybe do you want to avoid that each node peer with each others nodes.
For this, you can create dedicated route reflectors servers. (Minimum 2 servers for redundancy).
Here an example of configuration with frr, with rrserver1 (192.168.0.200) and rrserver2 (192.168.0.201).
If you have a lot of proxmox nodes, or multiple proxmox clusters, you may want
to avoid that all node peers with each others nodes.
For this, you can create dedicated route reflectors (RR) servers. As a RR is a
single point of failure, a minimum of two servers acting as an RR is highly
recommended for redundancy.
Below is an example of configuration with 'frr', with `rrserver1
(192.168.0.200)' and `rrserver2 (192.168.0.201)`.
