i want to run ospf on atm pvc circuit must i add command "ip ospf network broadcast" to router's atm subinterface configuration? (atm subinterface is configured as point to point) i know that if i haven't add this command,the atm subinterface network type is point to point, if i add ,the network type is broadcast. i met this problem before, i rememer that i must set the subinterface to broadcast type to run ospf. but it seems as if not be so from what i read from book.can anybody tell me the truth ? thanks a lot _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
