PXE boot over DMVPN not working

w.wolkers · ‎05-24-2012

Hi,

I'm trying to get PXE booting working over a DMVPN link.

I'm currently at the point that the PC gets an IP address, and then tries the TFTP boot, but I get the message:

PXE-E32: TFTP open timeout

PXE-M0F: Exiting Intel Boot Agent.

The BVI1 interface is setup with 2 ip helper-addresses, 1 for the DHCP server, 1 for the TFTP/PXE server. Booting from PXE works fine at the main site.

The config of the DMVPN Spoke is attached.

I'm currently guessing this has something to do with MTU settings and TFTP, but I'm at a loss at the moment.

Check that you can TFTP using another PC.

Hi, did you resolve this? I'm experiencing the same issue and would appreciate any suggestions.

Thanks,
