isdn backup over ospf

[pccthailand]

Hi

I have seen my router logs , i found this debug messages.

" Di1 DDR: Cannot place call, no dialer string set "

I think, this cause from ospf hello interval . how can i prevent router to sent hello message on dialer ( when it's not used for backup)

thanks

You can either not configure OSPF at all on that interface or configure it using the OSPF demand circuit feature.
