Hi all. I was working on a lab with an ISDN link between two of my OSPF routers. The link would come up if the Frame cloud went away. Normal stuff link would be initiated as usual. However, since area 0 had authentication turned on broadcasts from 224.0.0.5 kept the isdn link up all the time. If I filtered out the 224.0.0.5 from being interesting the ospf neighbors would get terminated at the dead interval. When I turn off authen. from area 0 all worked as normal.
Is this a normal occurrance? When area authentication is turned on do the key exchanges still happen even over a demand-circuit? Thanks...
