Lab Objective:
The focus of this lab is to understand Cisco IOS IP SLA Operations and BGP implementation and configuration in Cisco IOS routers. Additional technologies include EOT.
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
Enable BGP on R1, R2 and R3 as illustrated in the topology. Use the physical interfaces for the BGP peering. Advertise the LAN subnets on R2 and R3 via BGP. Do NOT advertise the LAN subnet between R1 and R4 via BGP. Verify the configuration using the appropriate commands.
Task 3
Configure R1 so that R2 and R3 are able to reach the LAN subnet between R1 and R4. You must adhere to the following restrictions when completing this task:
1. Do NOT advertise the 150.1.1.0/24 subnet via BGP
2. Do NOT redistribute the connected subnet into BGP
3. Do NOT advertise a default route via BGP
4. Do NOT configure static routes on either R2 or R3
You are allowed one static route, which can NOT be a default route, on R1. This route can be advertised via BGP using the network x.x.x.x mask y.y.y.y command. This route should have a network mask no longer than a /16, i.e. a mask no longer than 255.255.0.0. Verify the configuration using the appropriate commands.
Task 4
Configure R4 so that it is able to ping the 150.2.2.0/24 and 150.3.3.0/24 subnets and vice-versa. Verify your configuration using standard and extended pings.
Task 5
Configure a Cisco IOS IP SLA Operation on R1 so that when the LAN connection between R1 and R4 is down, the route advertised in Task 3 is withdrawn and is no longer advertised. Test your solution by disabling the LAN interface on R1.
