Morning Lazarus!
I have learned so much with this lab! The only incorrect result that I’ve noticed thus far is the mac and wildcard for this particular solution (3.4.10) and it could still be that I just misapplied the answer. I used deny ip 0.0.0.0 255.255.255.255 255.255.252.0 0.0.3.255 to catch and deny anything ge /22 and my output is this:
R9# show ip route bgp

Thank you again so much for this and the other routing labs you guys have put together! I love working through these!
