9. Configure the VRF instance defined in the previous step on interface xe-5/3/1, which

connects with the CE device:

EX9208# set routing-instances VPN1 interface xe-5/3/1.0

10. Configure OSPF for routing between CE and PE devices. This step binds the VRF

instance called VPN1 to the routing protocols or static routes used at customer sites:

EX9208# set routing-instances VPN1 protocols ospf area 0.0.0.0 interface

xe-5/3/1.0

EX9208# set routing-instances VPN1 protocols ospf export default-export

EX9208# set routing-instances VPN1 protocols ospf import default-import

11. Configure the PE device to redistribute routes learned from CE devices into MP-

BGP. This example uses the routes learned from OSPF or BGP, but other routing

protocols or static routing could be used with other VRF instances. This example

redistributes routes from a policy statement called “Tsunami1”:

EX9208# set policy-options policy-statement Tsunami1-export-policy term 1

from protocol ospf

EX9208# set policy-options policy-statement Tsunami1-export-policy term 1

from protocol /jointfilesconvert/492162/bgp

EX9208# set policy-options policy-statement Tsunami1-export-policy term 1

then community add Tsunami1

EX9208# set policy-options policy-statement Tsunami1-export-policy term 1

then accept

EX9208# set policy-options policy-statement Tsunami1-export-policy term 2

then reject

EX9208# set policy-options policy-statement Tsunami1-import-policy term 1

from protocol /jointfilesconvert/492162/bgp

EX9208# set policy-options community Tsunami1 members target:100:2

EX9208# commit

On Juniper MX80 (P device):

The steps involved for configuration of a P device include the following:

• Configuring a loopback address

• Configuring addresses on interfaces connected to CE and P devices

• Enabling LDP

• Enabling MPLS

• Configuring a backbone IGP (in this case, OSPF)

1. Define loopback interface lo0 and configure an IP address for that interface. This

address will serve as the PE device’s router ID for BGP and LDP:

mx80> configure

mx80# set groups global interfaces lo0 unit 0 family inet address
