Hello group, I'm now starting Section 1 and i have some comments i would like to see discussed:
Task 1.2) In the 7200/ATM topology, R2 is not directly connected to R5. R2 connects to R4 and R4 connects to R5. So if this true, this task is not so trivial as it seems. I lost several hours to make it work. Basically i configured CRB in R4 and IRB in R2 and R5. With the release i was using, the bridge was not working. Then i moved to another release and the bridge started passing traffic. Then i found another problem with IP traffic from R1 to R5. The solution was using PPP between R2 and R5 instead of HDLC. Task 1.3) Why do we need "no arp frame-relay" ? I'm convinced that this command has not effect at all. And we don't need to configure IETF in R1. The routers are smart enough to communicate even if the encapsulation is IEFT in one side an CISCO in the other end. Task 1.4) The default OAM timers are enough to make it faster than ISIS. Task 2.2) Is this minimal configuration ? My options were area-password and domain-password. And instead of using L2-to-L1 route leaking, why don't we simply send the default route from R1 and R5 to R2 ? Task 3.3) Isn't the command "timers throttle spf" also valid for iSPF ? Thanks.
