Lab 176 - MPLS VPN using BGP

Prerequisites: CCNP level skills.

Note!

This lab layout is based on the new physical topology presented here. This lab assumes that you have successfully configured ALL previous MPLS labs.

IMPORTANT!
As per recommendation ALL loopback addresses on P and PE routers will use /32 network mask! 
PE routers are: R1, R3, SW3.
P router is: R2
All other devices are CE routers in this MPLS topology. 

Topology

Pic. 1 - MPLS Topology.

Task 1

Configure two additional loopback interfaces in BB1 and advertise all of them using OSPF. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.111.1/26
• Loopback2 = 192.168.111.65/26

Task 2

Configure two additional loopback interfaces in SW4 and advertise all of them using RIPv2. The new loopback addresses should be as follows:

• Loobpack100 = 192.168.100.1/26
• Loopback200 = 192.168.100.65/26

Other subnets (configured in previous labs) should not be advertised in BGP. Do not use network statement under BGP to accomplish that

Task 3

Configure BGP peering between BB1 (CE) and its PE router (SW3) and between SW4 (CE) and its PE router (R3). Make sure that subnets configured in Task 1 and Task 2 are advertised using BGP protocol and are reachable between the sites. Use L3 VPN to accomplish that.

NOTE!
You will need to create a new vrf on R3 (VRF D). Assign whatever rd you want, but then you will have to override the int f0/0.103 vrf forwarding config from lab 174 by assigning this interface to newly created vrf D.

Task 1

Configure two additional loopback interfaces in R4 and advertise all of them using OSPF. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.4.1/27
• Loopback2 = 192.168.4.33/27

Task 2

Configure two additional loopback interfaces in R5 and advertise all of them using OSPF. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.5.1/27
• Loopback2 = 192.168.5.33/27

Advertise Loopback0 address 10.0.8.8 of SW2 in OSPF (almost forgot - thanks Tom for today's comment).
DO NOT enable ospf peering between R4 and R5 on their direct LAN connection (for now, since I want to come back to it later).

Task 3

Configure devices such that SW2, R4, and R5 subnets are reachable. Use layer3 VPN to accomplish this.

Task 1

Configure two additional loopback interfaces in SW1 and advertise all of them using EIGRP. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.7.1/28
• Loopback2 = 192.168.7.17/28

Task 2

Configure two additional loopback interfaces in SW4 and advertise all of them using EIGRP. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.10.1/28
• Loopback2 = 192.168.10.17/28

Task 3

Configure routers such that SW1 and SW4 subnets are reachable. Use peer-to-peer VPN to accomplish this.

Task 1

In R6 configure four additional loopback interfaces and advertise all of them using RIPv2. The new loopback addresses should be as follows:

• Loobpack1 = 192.168.6.1/29
• Loopback2 = 192.168.6.9/29
• Loopback3 = 192.168.6.17/29
• Loopback4 = 192.168.6.25/29

Task 2

Configure PE router (R1), to accept prefixes advertised by R6 using RIPv2 protocol. Make sure that R1 can accept RIPv2 prefixes from other potential CE routers with overlapping addresses.

Task 1

On all LDP enabled routers advertise the labels of the loopback0 subnets. All transit subnet addresses should not advertise their local labels.

Task 2

Verify the configuration. If successful, remove the configuration done in Task 1.
