Hey all, I’m loving this lab! Have a quick question regarding 3.4.10 BGP Route Filtering. Looks like the task is to filter out all /22 and above but the output of R9 shows routes with both /22 and /23. My mask and wildcard differed from the solution and I filtered out any prefix with a mask of /22 or greater. I was just wondering if I misunderstood the ask. Thanks again for the lab!
Notice that all prefixes ranging from /22 to /32 have been removed from the BGP table. The task is complete.
