Hi Laz,
I do have one follow up question. I went through the example in the Auto-Summary lesson to experiment as you suggested. I have it configured exactly the same as in the lesson.
To quote “If you specify the wildcard mask, EIGRP will take all networks configured on interfaces that fall within the specified range. The only exception is loopback addresses, which, regardless of the subnet mask on the interface, they are always advertised as /32 networks”
In the example above the Loopback0 “1.0.0.0/8” doesn’t look to be advertised as a /32 network. Can you just explain that bit out for me please?
