Using 2 MPTCP Routers in Active/Active mode with a local VIP (VRRP) for routing

[murateri75]

Hello
I have 2 RaspberryPI 4B configured with the same VPS.
I want to have some kind of High Availability (if one of the Raspberry fails the other is managing the MPTCP protocols for Internet bonding of my two DSL connections)
How can I do that ?
When I have both MPTCP routers actives only one is working well (connected to VPS as there only one VPS) The other says connection failed.
Should I have 2 VPS with two different MPTCP tunnels with local VIP for routing and VRRP protocol ?
Or is it possible that both MPTCP routers connect and mount a tunnel with the VPS server ?

I am using OpenMPTCP 0.60 version with Kernel 6.1 on VPS (Debian 12)
Thanks for any idea on this

I m just seeing that there is a new 0.61 version with Kernel 6.6
Perhaps good to upgrade before doing something else ?
