ip helper-address operation

Unanswered Question
Nov 13th, 2007

When you have multiple ip helper-addresses configured on an interface, does the router/L3 switch forward the UDP packets in the same order as they are configured or does it forward them to all of the helper addresses configured, regardless of order?

In otherwords, do you need to configure the helper addresses in the same order to match your primary, secondary, tertiary DHCP servers or does the router forward to UDP to all configured helper addresses?

I have this problem too.

The order in which you list the helper addresses does not matter because the router will forward to every helper address configured.
