Included with a subscription
Build a two-router, two-LAN EIGRP domain and practice precise wildcard-masked network statements so only the intended interfaces participate. R1 has an extra LAN on Ethernet0/2 (172.16.99.0/24) that must be excluded from EIGRP. Validate with show commands and end-host pings that the correct LANs are exchanged and the excluded LAN is not advertised.
Hands-on CCNA ACL practice using standard ACLs and wildcard masks to allow a single host, a contiguous range, and an entire subnet while proving a deny. You will place the ACL near the destination, order statements correctly, verify with end-host pings and ACL counters, and troubleshoot common mistakes.
