Lab 2. MPLS VPN

Here step-by-step configuration MPLS VPN:

In PE Router:

1. Create VRF
2. Activate VRF in interface that connected to CE Router and then add IP address
3. Activate MP-BGP
4. Activate routing PE-CE

In CE Router:

1. Add IP address in CE
2. Configure default route or routing CE-PE

Let’s continue the lab from previous lab http://pursuingmydestiny.blogspot.com/2011/12/lab-1-mpls-backbone.html

Let’s take example

PE1#

ip vrf BRI_1                    ---- > create vrf. In vrf there are rd & route-target need to be set

 rd 65000:1

 route-target export 65000:1

 route-target import 65000:1

!

interface Loopback1        ---- > this loopback just for testing the vpn vrf BRI_1

 ip vrf forwarding BRI_1       

 ip address 1.1.1.1 255.255.255.255

!

interface FastEthernet0/1

 description ###Link to BRI1###

 ip vrf forwarding BRI_1     --- > activate vrf in interface to CE then add ip address

 ip address 192.168.0.1 255.255.255.252

!

router bgp 65000

 address-family vpnv4        ---- > activate MP-BGP

  neighbor 10.10.10.2 activate

  neighbor 10.10.10.2 send-community extended

  neighbor 10.10.10.2 next-hop-self

PE2#

ip vrf BRI_2

 rd 65000:1

 route-target export 65000:1

 route-target import 65000:1

!

interface Loopback0

 ip address 10.10.10.2 255.255.255.255

!

interface Loopback2

 ip vrf forwarding BRI_2

 ip address 22.22.22.22 255.255.255.255

!

interface FastEthernet0/1

 description ###Link to BRI2###

 ip vrf forwarding BRI_2

 ip address 192.168.0.5 255.255.255.252

!

router bgp 65000

 address-family vpnv4

  neighbor 10.10.10.1 activate

  neighbor 10.10.10.1 send-community extended

  neighbor 10.10.10.1 next-hop-self

Please verify vrf
