Q:Can I just Use passive interfaces to reduce the CPU processing?
A:Passive interfaces with no requirements for adjacencies will reduce CPU processes, but a superior way to enable this within EIGRP exists.
Q:If I use the neighbor command, won't that be sufficient as i will no longer be multicasting my EIGRP "hellows"?
A:This will not be sufficient.
Q:I have modified my hellow timer on R8 and now my routes are flapping.Is this aceptable.
A:No,you need to remember that R8 will have formed a neighbor relationship on VLAN2;you should ensure that all routers are configured in the same manner.
Q:I have configured R6 and R8 with identical hellow intervals but I find that my routes are still flapping.Is this aceptable?
A:No,you should maintain a reliable neighbor relationship with R4; consider adjusting other EIGRP parameters.
