probleme in network configuration

[khalil31]

I'm trying to configure 3 bridges in my Proxmox servers but I'm unable to ping the configured ips, what's wrong with this configuration ? Thanks.

auto lo
iface lo inet loopback

iface eno3 inet manual
iface eno4 inet manual
iface eno2np1 inet manual
iface eno1np0 inet manual

auto vmbr0
iface vmbr0 inet static
address 10.10.3.34/24
gateway 10.10.3.254
bridge-ports eno3
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet static
address 192.168.1.34/24
gateway 192.168.1.3
bridge-ports eno4
bridge-stp off
bridge-fd 0


auto vmbr2
iface vmbr2 inet static
address 10.20.2.4/24
bridge-ports eno1np0
bridge-stp off
bridge-fd 0
# bridge-vlan-aware yes

You shouldn't set 2 gateways. But I think this won't fix it.
From where to where do you try to ping?
If you got no router that routes between them you need to be in the same subnet, so you need to be on the same bridge.
