Zero to Hero Network Engineer

Configure VLANs 10, 20, and 30 across a collapsed core topology, create dot1q trunks between switches, and verify inter-switch connectivity with gateway IPs in VLANs ten, twenty, and thirty.

Enable cdp and lldp on switches to view topology, using show cdp neighbors and show cdp neighbor detail to identify connected ports and remote device information.

Learn to configure port channels between switch three and switch four by creating a port-channel and adding ports 0/1 and 0/2 with channel group and mode on.

Configure spanning tree across VLANs, verify root bridges, and adjust priorities on switches. Explore rapid spanning tree, port fast, BPDU guard, and root guard to improve convergence.

Configure HSRP between switch one and switch six to provide a virtual gateway for VLAN 30, enable preemption, and verify the active gateway with show standby for reliable routing.

Set up your BGP Grid unit lab server, log in, create or import labs, add routers and switches, connect nodes, and manage network configurations with templates.

Configure EIGRP between switch one and switch six, removing OSPF and setting the AS number, then advertise Ethernet zero three networks with wildcard bits. Add a loopback and verify neighbors.

Configure DHCP on a layer 3 switch, set a DHCP pool with network and gateway, exclude the gateway address, and verify assignment to the host VPC.

Demonstrates configuring a dmvpn hub-to-branch vpn over mpls, including vrf setup, tunnel interfaces, ip addresses, network ID, and authentication key, and adjacency formation.

Configure OSPF authentication between routers 12 and 13 using md5 with key 81 and password camp, enable cryptographic authentication in area zero, and verify adjacencies.

Explore SRP load balancing, compare equal and unequal cost paths across switches four, five, six, and three; apply the variance command with feasible distance and feasible successor to loopback.
