Connect to vm from another vm

[KGMK]

Hello,

I have 4 virtual machines on my Proxmox setup. From the PVE host I am able to access all network interfaces and ping all computers from network.

When I run arp -a from my PVE I am getting these IP's:

mail.supportdedicated.com (135.181.4.202) at ce:f2:a3:70:c8:b0 [ether] on vmbr2
static.193.4.181.135.clients.your-server.de (135.181.4.193) at e4:5d:37:09:f6:85 [ether] on enp35s0
windows.204.4.181.135.clients.your-server.de (135.181.4.204) at 26:50:cd:8d:5b:f0 [ether] on vmbr0
static.203.4.181.135.clients.your-server.de (135.181.4.203) at a6:b0:f2:b3:cd:de [ether] on vmbr1

When I run arp -a from one of the other machines (let's say 135.181.4.203) I am only getting this:

? (135.181.4.233) at 62:90:64:2d:5d:af [ether] on ens18

Here is my network interface file:

### Hetzner Online GmbH installimage

auto lo

    bridge-stp off
    bridge-fd 0
    up ip route add 135.181.4.203/32 dev vmbr1

auto vmbr2
iface vmbr2 inet static
    address 135.181.4.233
    bridge-ports none
    bridge-stp off
    bridge-fd 0
    up ip route add 135.181.4.202/32 dev vmbr2

How do I get vmbr0 to access vmbr1? Someone please help? In other words, how can I get vmr0 to ping vmbr1?

I solved it by adding:

up ip route add 135.181.4.204/32 dev vmbr1

to vmbr1
