And also, if you have NOT issued the command clear frame inarp (12.1 and above) or clear frame-inarp (12.0 and below), the map statements will remain until you reload the routers. That will need to be done on router B and router C. Routers B and C do not form adjacencies with each other in this topology *unless* you make use of the full mesh, which you've been instructed *not* to do. They both form adjacencies with Router A. That's why you add a map statement to each Router B and Router C to point them to each other via their respective DLCI's to Router A, unless you're explicitly told not to do that. (Which is whole different can of worms) My strategy is shut off inverse arp, clear frame inarp, get the map statements into the config, write the config, and reload. You may wish to reschedule your Feb lab date if you're at this point with OSPF and frame relay a month or so away from your lab. It only gets more complex than this, and this concept, while not elementary, is 'core' to your success in the lab exam. > -----Original Message----- > From: Wilson, Christian [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 10, 2002 12:23 PM > To: [EMAIL PROTECTED] > Subject: Frame relay map 0.0.0.0 question, please help!
