How the local loop address can be decided?

[K.FUJIWARA]

I understand how to configure the local loop interface, and for what it is used in OSPF. But I can't make sence about the way to decide the local loop address. Please tell me easy way. ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
