Hi Chuck >From the look of the problem the best solution to the problem would be to move the redistribution from R1 to R2 and run OSPF over the link. Which then allows you to use an OSPF Demand Circuit reducing the time the link is up.
But if the problem specifically mentions that EIGRP must be redistributed on R1 then from the look of the instructions all you need is an Access list that allows no broadcast IP traffic to initiate the link and allows Multicast packets to initiates the link so EIGRP is able to form a neighbour relationship. From memory there is no version of Snapshot for EIGRP, but I could be wrong. If there was that would be the answer. Hope I haven't confused you more Chuck :) Vince ----- Original Message ----- From: "The Long and Winding Road" To: Sent: Sunday, March 23, 2003 4:26 PM Subject: Sanity Check - ISDN and EIGRP [7:66016] > I'm working on a practice lab problem. > > there are two domains - OSPF and EIGRP > > The two domains can only communicate via ISDN > > OSPF---R1-------ISDN------R2----EIGRP > > R1 is where redistribution takes place.
