[j-nsp] BOOTP helper on MX vrf

[Peter Krupl]

Hi,

I have the following configuration working on an MX240 running 12.2R3.5.
--------------------------------------------CUT--------------------------------------------
set routing-instances 1023 forwarding-options dhcp-relay server-group SRV 10.1.1.33
set routing-instances 1023 forwarding-options dhcp-relay active-server-group SRV
set routing-instances 1023 forwarding-options dhcp-relay group all active-server-group SRV
set routing-instances 1023 forwarding-options dhcp-relay group all interface ge-2/0/2.85
set routing-instances 1023 forwarding-options dhcp-relay group all interface ge-2/1/9.806
--------------------------------------------CUT--------------------------------------------

Until now it has been running perfectly.

Subject: [j-nsp] BOOTP helper on MX vrf

Hello,

as I'm hearing conflicting information regarding bootp helper on MX routers in a vrf routing-instance, has anyone a working configuration?

What I need:

Forward DHCP broadcast requests from one vrf interface to a central DHCP server in the same VRF (classical bootp helper functionality). I don't want bootp helper on *every* interface, just a few.

So any information regarding this is appreciated.

Regards

Sebastian
