Remember that the virtual link is part of area 0, so did you do area 0 authentication message-digest?
Also how did you specify the key.. Router ospf 100 Area 0 authentication message-digest Area X virtual-link a.b.c.d message-digest-key 1 md5 password This must be on both routers. I am working on a lab as I type and this worked fine for me... Here is a sample on the Cisco Site http://www.cisco.com/warp/public/104/27.html Thanks Larry -----Original Message----- From: James Johnson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 28, 2002 2:27 PM To: [EMAIL PROTECTED] Subject: OSPF virtual link authentication [7:52238] My OSPF link will not come up. I'm trying to do MD5 authentication across a virtual link. I thought there was a trick to this but I can not remember. Any help?
