Lab ips-09 - QoS Classification and Marking
Configure QoS classification and marking on R1 with class-maps and a policy-map: match the traffic that matters, tag it with DSCP values like EF and AF41, and attach the service-policy to an interface.

Lab ips-08 - SNMPv2c vs SNMPv3
Configure SNMPv2c community strings and an SNMPv3 user and group with authentication and encryption on R1, set system location and contact, and see exactly why v3 is the modern default and v2c is legacy-only.

Lab ips-07 - Syslog and Buffer Sizing
Point R2's logs at R1 as a central syslog destination with sensible buffered, console, and trap settings. Covers the logging commands, the eight severity levels, millisecond timestamps, and the log volume vs visibility trade-off.

Lab ips-03 - Static NAT Inside/Outside
Static NAT maps one inside private IP to one outside public IP, permanently and bidirectionally. This lab makes 10.20.0.100 reachable as 192.0.2.100 and shows you how to read the translation table.

Lab ips-02 - DHCP Relay (ip helper-address)
DHCP discovers are L2 broadcasts and do not cross routers. This lab configures ip helper-address on R2 to relay client requests to a DHCP server on another segment, and explains the GIADDR field along the way.
paid
Lab ips-05 - NAT Overload (PAT)
Configure NAT overload (PAT) on R2 to share one outside IP across all inside hosts. You read the translation table with its port columns and see why PAT is the NAT pattern nearly every production network actually runs.
paid
Lab ips-04 - Dynamic NAT with Pool
Configure dynamic NAT on R2 with a pool of public addresses, control which inside hosts translate with an ACL, and see how dynamic NAT differs from PAT and what pool exhaustion looks like.

Lab ipc-13 - VRRP vs HSRP Comparison
Run VRRP alongside HSRP on the same routers to see how similar they are and where they differ: Master vs Active terminology, the 0000.5e00.01XX virtual MAC, and reading show vrrp. Includes the full comparison table.
paid
Lab ipc-12 - HSRP Active-Standby
Configure HSRP between R1 and R2 on the base topology: virtual IP, virtual MAC, priority, and preemption, plus how to read show standby and show standby brief when the Active router fails.

Lab ips-01 - IOS XE as a DHCP Server
Configure Cisco IOS XE as a DHCP server: the ip dhcp pool syntax, excluding addresses from the pool, and reading show ip dhcp pool and show ip dhcp binding as HOST1 pulls an address automatically.

Lab ipc-14 - GLBP Active-Active Load Balancing
GLBP can use all routers in the group at once: the AVG answers ARP with different virtual MACs so hosts spread traffic across multiple forwarders. Configure it between R1 and R2 and watch the AVG and AVF roles split.
