Tested the different voucher codes. Not working.

Not working!!

Based from the instruction: "If both r11 and r12 are declared unreachable from a preferred gateway, the other switch must be allowed to assume the gateway role." With this statement, do you mean that boolean "AND" should be used instead of "OR", even the instruction says that if "both r11 and r12 are declared unreachable from a preferred gateway". From my understanding, once both of the tracking are down that's only the time it will trigger the failover. Because if the answer is boolean "AND", then the instruction should say something that even one of the links are down that it will failover right away, but that's not the case here. In my opinion, it should use boolean "OR".

Conclusion: 1. IP SLA - From SW101 and 102, ping R11 and R12 loopback; source is physical interface 2. Use track list boolean OR As the tasks says "If both r11 and r12 are declared unreachable from a preferred gateway, the other switch must be allowed to assume the gateway role.", then boolean OR should be used since it will only trigger the failover when BOTH uplinks (to R11 and R12) are down. Because if the task says that even atleast one of the links go down that the gateway has to swing, then boolean AND should be used. But I think that's not the case for this particular task.

For this question, after multiple testings, I sourced from the physical interfaces instead for the SLA tracking, technically the SW101 itself for example is still the gateway for VLAN 2000, while SW202 is the gateway for VLAN 2001. Then used the Boolean OR. Upon testing, when I both shut down the physical interfaces of R11 and R12 facing SW101 for example, that's ONLY the time that the gateway swinged to SW102. Same logic for the other side (from R11 and R12, facing SW102).

thanks. working fine

Thanks a lot
