Re: [lwip-users] Interface with PPPoE and DHCP?

[Richner Simon]

Dear Simon,

 

The title of this discussion refers on the last part of my original post that so far nobody commented on:

 

    My last idea was to use DHCP and PPPoE in parallel. So if there was no DHCP server, the laptop would use PPPoE.

 

From the answers I got so far, I guess that this is no common approach.

Never the less: 

 

=> Would it be possible to use PPPoE and DHCP on the same interface in parallel?

 

PS: Setting LWIP_DHCP_AUTOIP_COOP_TRIES to 1 takes 45s to get an IP for <LwIP 1.3.2> and 85s for <WindowsXP-SP3>, what I'm after is "plug & play" (max. 3 seconds). 

 

Simon

Some devices are connected to a network, using DHCP to get an IP address. Other devices are setup for standalone use and are directly connected to a local laptop for maintenence. In both cases I want to use the same ethernet connetion with the same software.

Ehrm, what exactly does this have to do with PPPoE? I don't think I understand this...

Anyway, we also have built a scan-and-config tool that can talk to misconfigured devices or devices that don't have an IP yet. I don't think AutoIP takes too long here when used in together with DHCP, but our tool even shows the devices before they have an IP address (and you can see the DHCP/AutoIP state).

However, this only works using broadcasts unless the device has a correctly unicast-working  IP address.
