Lab Objective:
The focus of this lab is to understand Gateway Load Balancing Protocol (GLBP) implementation and configuration in Cisco IOS routers. Additional technologies include security and timers.
Lab Topology:
The lab network topology is illustrated below:
|
IMPORTANT NOTE If you are using the www.howtonetwork.net racks, please bring up the LAN interfaces connected to the routers by issuing the no shutdown command on the connected switches. If you are using a home lab with no interface fastethernet 0/0 Alternately, you can simply connect the interfaces to a hub or switch if you have one available in your own lab. |
Task 1
Configure hostnames, IP addressing on all routers as illustrated in the network topology.
Task 2
Configure EIGRP as illustrated in the topology. Redistribute the LAN subnets into EIGRP.
Verify your configuration using the appropriate commands on all routers in the network.
Task 3
Configure GLBP on R1, R2, and R4. Ensure that R1 is elected AVG. R2 should be standby. The gateway IP should be 150.1.1.254. Verify your configuration using the appropriate commands.
Task 4
Configure MD5 authentication for GLBP. Use a password of ‘CCNP’ for authentication and a key chain named GLBP. Verify your configuration using the appropriate commands.
Task 5
In the future, NAT will be implemented on R1, R2, and R3. In preparation for this, configure GLBP so that a host will be guaranteed to use the same virtual MAC address as long as the number of Virtual Forwarders (VFs) in the GLBP group is constant. Verify your configuration using the appropriate commands.
Task 6
To allow for faster failover of GLBP, configure R1, R2 and R4 so that the gateways send five Hellos every second. If four Hellos are missed, then GLBP should be declared down. Verify your configuration using the appropriate commands.
