Challenge Lab 2

The following challenge lab tests your ability to configure tag switching, BGP, and MP-IBGP.

Challenge Lab 2 385

10.4.0.010.4.0.0

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

386 Appendix A Challenge Labs

Tag Switching

This section includes the following lab exercise:

Lab 2.1: Configure tag switching

L A B 2 . 1

Configure tag switching

1.Configure tag switching on PE1.

2.Configure tag switching on P1.

3.Configure tag switching on P2.

4.Configure tag switching on PE2.

BGP

This section includes the following lab exercise:

Lab 2.2: Configure BGP

L A B 2 . 2

Configure BGP

1.Configure BGP AS 65000 on PE1.

2.Add an I-BGP neighbor statement for PE2 (use the Loopback 0 address).

3.Configure BGP AS 65000 on PE2.

4.Add an I-BGP neighbor statement for PE1 (use the Loopback 0 address).

MP-IBGP

This section includes the following lab exercise:

Lab 2.3: Configure MP-IBGP

Challenge Lab 2 387

L A B 2 . 3

Configure MP-IBGP

1.On PE1, activate neighbor PE2.

2.On PE1, configure PE1 to send both standard and extend communities to PE2.

3.On PE2, activate neighbor PE1.

4.On PE2, configure PE2 to send both standard and extend communities to PE1.
