First things first, great lab! I am only a few labs in to vol1 but already appreciate the quality. There are a couple of things I could do with some clarity on... Appreciate any ones time.
First thing. The solution to one task was to use a virtual template, assign it to both dlci's, add chap authentication, and enable ppp multink. The same virtual template is then used on single dlci's to other routers. This is all fine. The one query I have involves the ip addressing. The solution assigns the ip address to the virtual template. Having listened to Marko on the AoD, in the ip addressing section, he describes that assigning the ip address to the virtual template, that is used for multiple clients would create multiple virtual access interfaces , and hence conflicting idb's. Which is a bad thing. I hence went along trying to address the virtual template with ip unumbered from a loopback. In the end had to peek at DSG. Question is why is it okay in this scenario? Next, hopefully simpler. When you disable inverse arp, I understand that the router will not send out inverse arp requests, but it will still respond. However I wouldn't expect it to learn dynamic mappings. In this lab I observed an interface still learning a dynamic mapping whilst no inverse arp on that interface. Is that expected.?
