Challenge Lab 5

The following challenge lab tests your ability to configure a VRF, a route distinguisher, a route target, static routes as a PE-CE routing protocol, and static route redistribution into MP-BGP. Note that the network is already set up with MPLS and MP-BGP (AS 65000).

You need to know all the interfaces and IP addressing contained in the

Challenge Lab 5 399

Service Provider Addressing

VRF Configuration

This section includes the following lab exercise:

Lab 5.1: Configure a VRF, a route distinguisher, and a route target

L A B 5 . 1

Configure a VRF, a route distinguisher, and a route target

1.On the Atlanta POP router, create a VRF called peer_vpn.

2.On the Atlanta POP router, assign a route distinguisher of 50:1.

3.On the Atlanta POP router, configure an import route target and an export route target of 50:1.

4.On the Atlanta POP router, associate the PE-CE interface with the VRF and assign the appropriate address from the table.

5.On the Raleigh POP router, create a VRF called peer_vpn.

6.On the Raleigh POP router, assign a route distinguisher of 50:1.

7.On the Raleigh POP router, configure an import route target and an export route target of 50:1.

8.On the Raleigh POP router, associate the PE-CE interface with the VRF and assign the appropriate address from the table.

Static Routes and Redistribution

This section includes the following lab exercise:

Lab 5.2: Configure static routes on the peer and PE devices and configure redistribution static routes and connected interfaces

400 Appendix A Challenge Labs

L A B 5 . 2

Configure static routes on the peer and PE devices

and configure redistribution static routes and connected interfaces

1.On Peer 1, configure a default route using the Serial 0 interface.

2.On Peer 2, configure a default route using the Serial 0 interface.

3.On the Atlanta POP router, configure a static route to the Loopback 0 interface of Peer 1 for the VRF.

4.On the Atlanta POP router, configure redistribution of the static route and the VRF connected interface.

5.On the Raleigh POP router, configure a static route to the Loopback 0 interface of Peer 2 for the VRF.

6.On the Raleigh POP router, configure redistribution of the static route and the VRF connected interface.
