is this supposed to be done in Packet Tracer ? What part do you have already configured, and what do you need help with ?


If this is a Packet Tracer project, post the zipped project (.pkt) file.

I have tried to do it on Packet Tracer cant do it. I need help with the whole thing thank you. I have uploaded the attachment you can take a look thanks again.

config the PVST for spanning tree
config HSRP group.


If the problem is you would like others to answer to all those questions then surly you won’t learn it for yourself correct?

If you simulate that network 90% of the answers you will get from just enabling those features and looking at the results.

Two things stand out which i hope others don’t provide you an answer to but you point you in the right direction is-

ospf loop backs - think of filtering 

spanning-tree ports- think of how it works with port-channels
