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. The ISDN link is in the EIGRP domain. Pretty much I've concluded that the only way this works is that here have to be static default routes on R1 and R2 pointing to eachother. The only other way I can see this working is for the ISDN link to be permanently up. Unfortunately, the lab instructions are not very clear on this point. The only relevant instructions are: 1) no broadcast packets should initiate a DDR session. Multicast packets should be able to traverse the ISDN link. 2) use an access-list 120 for any filters you may need for DDR 3) only IP traffic will need to traverse the link That multicast instruction is interesting. Am I on the right track thinking the test here is to let the link stay up forever by defining the EIGRP hellos as "interesting" ?? thoughts?
