Build an internal BGP (iBGP) peering between two IOS routers in the same AS over stable Loopback0 addresses, with OSPF providing loopback reachability. Each router originates a /24 from Loopback1 into BGP, and next-hop/peering behavior is validated from end hosts. This lab emphasizes the deterministic neighbor configuration (remote-as, update-source Loopback0, router-id) and exact-match network origination, supported by a minimal, secure OSPF core.

Advanced EIGRP capstone, run as a fault hunt. The branch LAN has disappeared from the network, one router sees only half its neighbours, and the routing process looks healthy on every device. Nothing was recorded. You get symptoms and the required end state — no fault list. Faults span all three routers, and two of them leave EIGRP running perfectly while doing nothing useful.

Inject a static default route from an edge router into an EIGRP domain so internal routers and hosts gain internet reachability. You will verify the D*EX 0.0.0.0/0 on the internal router and validate end-to-end connectivity from a branch host through the edge to an ISP-side server.

Implement classic EIGRP manual summarization on R1 to collapse four contiguous /24 loopback routes into a single /22 summary toward R2, reducing R2’s routing table entries while preserving reachability.

Build a 3-router EIGRP domain where R1 reaches R3’s loopback over two paths (direct and via R2). You will tune interface delay so the indirect path becomes the successor and the direct path remains a feasible successor, then enable variance to install both unequal-cost paths in R1’s routing table. Two Alpine hosts validate end-to-end reachability while router show commands confirm unequal-cost load sharing.

Harden EIGRP adjacencies with MD5 authentication between two iol-xe routers over a /30 transit, then validate that only trusted peers form neighbors. You will configure a key chain, bind it to the transit interface, and enable EIGRP (AS 100) to exchange two user LANs. Verification includes neighbor state, key chain presence, and end-to-end host reachability.

Configure a classic hub-and-spoke EIGRP domain where the single-homed branch (R2) is made an EIGRP stub, limiting query scope while still advertising its LAN. Validate that R1 flags R2 as a stub neighbor, routes still exchange, and query behavior is scoped appropriately.

Configure HSRP on two routers with a shared virtual gateway and speed up failover by tightening hello/hold timers to 1/3 seconds. Validate deterministic active/standby selection and confirm timer settings via show commands.

Implement two HSRP groups on a single VLAN so each router is Active for one group and Standby for the other. Two hosts split default gateways across the two virtual IPs for deterministic load-sharing with redundancy.

Harden an HSRP virtual default gateway with MD5 authentication so only trusted routers can participate. You’ll secure an existing HSRP group on two IOS routers that share a user VLAN via a single L2 switch. Validate the authentication state on both routers and confirm the endpoint still reaches the virtual IP.

Replace HSRP with open-standard VRRP to provide a shared virtual gateway on a single access VLAN. Configure VRRP group 1 with a common virtual IP and deterministic master/backup roles via priority and preempt. Validate using show vrrp commands and end-host pings.

Migrate a single-subnet LAN from HSRP version 1 assumptions to HSRP version 2, enabling group numbers above 255. Configure HSRPv2 on two routers that share one virtual default gateway IP so hosts retain gateway resilience without reconfiguration.

Troubleshoot and repair a pre-broken HSRP gateway on a single shared LAN. Two routers (R1, R2) and two clients (PC1, PC2) connect to a single L2 switch (SW1) in VLAN 10. The hosts intermittently lose gateway reachability because both routers act active due to seeded faults. Use show commands to diagnose, then correct HSRP so both routers share one virtual IP and R1 deterministically wins active.

Build an LACP Layer-2 EtherChannel between SW1 and SW2 so Rapid-PVST+ treats two parallel links as one logical Port-channel 7. Without EtherChannel, STP will block one of the two access links. With LACP active on both members and Port-channel 7 as an access port in VLAN 70, STP shows a single forwarding interface (Po7) and both physical links forward as one logical channel. Two hosts in VLAN 70 verify end-to-end connectivity.

Advanced EtherChannel capstone, run as a fault hunt. The uplink bundle between two access switches is not passing traffic and the hosts either side cannot reach each other. Some members are up, the bundle is not, and nothing was recorded. You get symptoms and the required end state — no fault list. Both ends of a bundle have to agree about several things at once, and only one end was touched during the change — so comparing them is the exercise.

Build a two-link LACP EtherChannel between two layer-2 switches as an access port for VLAN 60, then tune the global load-balancing algorithm to src-dst-ip so traffic distributes more evenly. Verify Po6 status, the hashing method, and end-to-end host reachability.

Build a Layer-3 EtherChannel between two IOS XE routers using LACP active/active. Two parallel router links are bundled into Port-channel5, which carries a /30 transit. R2 hosts a loopback; R1 installs a static route to reach it. Validate that the Port-channel holds the IP (members do not), that the bundle is up and uses both links, and that pings across the /30 and to the loopback succeed. Emphasis: deterministic EtherChannel configuration and Layer-3 port-channel practices.

Advanced CCNP troubleshooting lab: a pair of Layer-2 switches are connected by a two-link EtherChannel intended to carry VLAN 90 between access hosts. The starter configuration ships broken on purpose: the inter-switch bundle won’t form due to incompatible aggregation modes, and a trunk allow-list drift on one side prunes VLAN 90. Diagnose with IOS show commands, correct the EtherChannel mode so LACP forms the Port-channel, and restore trunk policy so same-VLAN hosts can communicate.

Build a routed LACP EtherChannel (Port-channel 8) between two iol-xe routers and route real inter-LAN traffic using static routes. Two parallel physical links (Ethernet0/0 and Ethernet0/1) on each router are bundled into a single Layer-3 Port-channel with a /30 transit. Each router serves a local /24 LAN with an alpine host. Validate that Po8 is up/up, static routes are present, and end-to-end host pings succeed across the aggregated uplink.

Use Rapid-PVST+ to elect different root bridges per VLAN across two parallel trunks, spreading VLAN 80 and VLAN 81 across distinct physical links without modifying path cost or port priority. Validate independent per-VLAN trees and confirm hosts in VLAN 80 can communicate over the surviving path. Includes a drift-check to diagnose/restore trunk allow-lists.

Advanced Rapid-PVST+ troubleshooting on a 3-switch triangle with a real Layer-2 loop. Two deliberate faults are seeded: an unintended root bridge wins VLAN 100 due to a mis-set/default priority, and PortFast/BPDU Guard are mistakenly applied on an inter-switch trunk. Two Alpine hosts in VLAN 100 verify user impact. Your job: use show commands to diagnose, then restore the correct root and remove edge features from the trunk while preserving them on access ports.

Hands-on CCNP OSPF lab comparing broadcast and point-to-point network types. Three routers share a multi-access Ethernet via an access switch to observe DR/BDR election, manipulate interface priorities, and then convert to point-to-point. Includes a user LAN behind R1 and realistic troubleshooting: neighbor stuck in 2-Way due to type mismatch, area mismatch isolating a router, and incorrect interface priority preventing desired DR/BDR roles.
