Do hold timer and hello timer should match in order to establish neighbor relationship between two routers running eigrp?
Thanks a lot!
Yes the router will advertise bandwidth and delay based on its own local interface.
1) EIGRP uses Dual all the time. Dual is the basic algorithm that EIGRP uses to select routes and to guarantee that the path chosen is loop free. Note that feasible successor is only a part of what Dual does.
2) when r2 sends an update it will advertise the lowest bandwidth of any link along the path and will advertise the sum of all the delays along the path.
It is helpful to understand that while OSPF does require that the timers match as a requirement for forming a neighbor relationship, EIGRP does not have this requirement. EIGRP will successfully form neighbor relationship between routers that have different hold timers and hello timers.
