Dear all,
I want to ask some questions about IPExpert lab 21. Some of them
are not technical question but the way to understand what is the task request
us to do.
1: In the switching part, it request us to change the spanning tree
age timer to 20. But I don't see any config relate to spanning-tree timer in
the final config. Is that "age timer" means max age in the result of "show
spanning-tree vlan xx"?

2: What is the meaning of "add loopbacks as deemed necessary"?? I
just put the loopback into routing process. Is that the task request to put
the loopback subnet as external route?
3: in the BGP part, it use "neighbor
x.x.x. local-as" to make R4,5,6 look ask AS600 in R7. But I don't think it
will work for the R2, which under AS610.
Regards,
Howard
