Question about different OSPF Process-IDs for single Area using "default-Information originate"

[whistleblower14]

Hi,

I´ve a technical question about the use of the "default-information orignate" command in OSPF! I`d like to anncounce a local static Default-Route into OSPF via two different Link-Networks to a L3 Stack! The Interfaces which connect the Router to the Stack-Members have already different Costs but that don`t influence the Default-Route because on the Stack I can see two entries for 0.0.0.0/0 learned - which probably indicate a Equal-Cost Link-Balancing?!
As I can see, when I setup two different OSPF Processes and put into each one of the Link-Networks with a "default-information originate /w different metrics" it seems to work as I`d like it to be, meaning that one Connection/Link is prefered over the other and the second one kicks in when the primary Link e.g. fails...
Can someone explain that behavior in more detail for me and tell me if this procedure is correctly used in the form?!

thanks in advance!
