IE VOL3 Core LAB 5 HELP
Hi experts, I’ve just completed IE Core Lab 5 using dynamips and i have some questions with regards to the solution guide that i hope the experts here can help me with.
1. Task 4.3 - Why is tunnelling needed? with connection to R1 down, router 3 and 6 are still on the lan, they still can contact each other and since they are both on area 0 there shouldn’t be a need to tunnel, am i missing something?
2. Task 4.4 - Why is the command “ip ospf network point-to-multipoint needed? I’m asking this because even without this command. My OSPF between R1, R2 and R5 still establishes. Is it because i’m using dynamips that the OSPF establishes?
3, Task 4.5 - Why is a virtual link from R1 and R2 need to be to R5? couldn’t R1 and R2 virtual link to each other straight away? from my dynamips lab it seems that R1 can link directly to R2 instead of having to go thru R5. again is this because of dynamips?
