Thanks for your feedback, Marvin. I didn't read the instructions carefully,
so I just assumed we couldn't add addresses, based on comments on classes I
took in the past. I will certainly read them next time.
My multicast question uses a specific scenario, but I was hoping even people
who doesn't have the IEWB material would be able to answer, since it's about
multicast verification. I understand that sometimes the problem may be IGP
related. Hopefully, this is not the case here. Anyway, my question is about
verification of multicast. Is there a rule to determine which source
interface is taken when using the command "ping 224.6.6.6" ? Is it
conclusive enough if I can ping with no extended commands?
I tried to enable pim dense-mode in all interfaces, just in case it's taking
an interface that is not multicast enable. Again, I still think the proper
test specifies the source interface as the one where the server is supposed
to be, right?
Thanks,
Andre
