Challenge Lab 3

The following challenge lab tests your ability to configure a VRF, a route distinguisher, a route target, RIPv2 as a PE-CE routing protocol, and RIPv2 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

Service Provider Addressing

VRF Configuration

This section includes the following lab exercise:

Lab 3.1: Configure a VRF, a route distinguisher, and a route target

L A B 3 . 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.

RIPv2

This section includes the following lab exercise:

Lab 3.2: Configure RIPv2 on peer and POP routers

Challenge Lab 3 391

L A B 3 . 2

Configure RIPv2 on peer and POP routers

1.Configure RIPv2 on Peer 1 for all networks.

2.Configure RIPv2 on Peer 2 for all networks.

3.Configure a RIPv2 context on the Atlanta POP router.

4.Configure a RIPv2 context on the Raleigh POP router.

Redistribution

This section includes the following lab exercise:

Lab 3.3: Configure redistribution

L A B 3 . 3

Configure redistribution

1.Configure redistribution between MP-BGP and the RIPv2 context on the Atlanta POP router.

2.Configure redistribution between MP-BGP and the RIPv2 context on the Raleigh POP router.
