Hello,
I am looking for a solution for the following problem:
I have a vyos-router with several vlan’s which should get their IP’s over unchanging dhcp servers.
I find only the dhcp relay service, which I can assign several interfaces.
So I should be able to start several dhcp-relay services.
Does anyone have an idea how I can realize with Vyos?
Best regards
Richard
If you have your interfaces configured correctly you should be able to add multiple DHCP servers to your DHCP relay config;
For example:
VLAN1 = 10.0.1.0/24 (eth0 & eth2)
VLAN2 = 10.0.2.0/24 (eth1 & eth3)
DHCP servers: 10.0.1.10 (VLAN1) & 10.0.2.10 (VLAN2)
Clients connected to eth2 (VLAN1) should have their DHCP requests answered by 10.0.1.10 and VLAN2 clients on eth3 by 10.0.2.10 respectively.
Please report back if this is working for you, i will add this as an additional example to the DHCP relay wiki article then.
Hello,
the answer does not quite meet my problem.
I have the following configuration:
eht0 = 10.10.10.0/24 (default-route)
eth1.11 = 10.10.11.0/24
eth1.12 = 10.10.12.0/24
DHCP Server1: 10.0.11.10
DHCP Server2: 10.0.22.10
So I need two “dhcrelay” processes and would configure this if this is going through VYOS.
As an alternative I found the file “/opt/vyatta/etc/config/scripts/vyatta-postconfig-bootup.script”.
Here I can configure the DHCP Relays
nohup /usr/sbin/dhcrelay -d -i eth1.11 10.0.11.10 &
nohup /usr/sbin/dhcrelay -d -i eth1.12 10.0.22.10 &
I would like to avoid this path.
I would like to find a solution like the Cisco IOS where I can configure dhcp-server for each interface (ip helper-address)
Best regards
Richard
Did you ever find a fix for this?
