2. Define IP addresses for interfaces xe-0/0/1 and xe-0/0/2 (connected to the Juniper

Virtual Chassis and Cisco Nexus 7010, respectively, each acting as PE devices):

mx80# set interfaces xe-0/0/1 description "to Juniper Virtual Chassis xe-

5/0/5"

mx80# set interfaces xe-0/0/1 unit 0 family inet address 192.18.38.2/24

mx80# set interfaces xe-0/0/2 description "to Cisco Nexus 7010 e3/10"

mx80# set interfaces xe-0/0/2 unit 0 family inet address 192.18.70.2/24

3. Configure LDP as the MPLS backbone label distribution protocol:

mx80# set protocols ldp interface xe-0/0/1.0

mx80# set protocols ldp interface xe-0/0/2.0

mx80# set protocols ldp interface lo0.0

4. Enable MPLS on the interfaces connected to PE devices:

mx80# set protocols mpls interface xe-0/0/1.0

mx80# set protocols mpls interface xe-0/0/2.0

mx80# set interfaces xe-0/0/1 unit 0 family mpls

mx80# set interfaces xe-0/0/2 unit 0 family mpls

5. Enable OSPF on the service provider network. IS-IS would also work as an IGP:

mx80# set protocols ospf area 0.0.0.0 interface xe-0/0/1.0

mx80# set protocols ospf area 0.0.0.0 interface xe-0/0/2.0

mx80# set protocols ospf area 0.0.0.0 interface lo0.0

mx80# commit

Cisco Catalyst 3850 (CE device):

1. Configure IP addresses for interfaces t1/1/3 (connected with the Juniper Virtual

Chassis) and g1/0/2 (connected with the Spirent TestCenter test instrument):

c3850# configure terminal

c3850(config)# interface TenGigabitEthernet1/1/3

c3850(config-if)# description to Juniper Virtual Chassis int xe-5/3/1

c3850(config-if)# no switchport

c3850(config-if)# ip address 192.18.1.2 255.255.255.0

c3850(config-if)# no shutdown

c3850(config-if)# interface GigabitEthernet1/0/2

c3850(config-if)# description to stc

c3850(config-if)# no switchport

c3850(config-if)# ip address 192.18.18.1 255.255.255.0

c3850(config-if)# no shutdown

c3850(config-if)# exit

2. Enable OSPF on the interfaces defined in the previous step:

c3850(config)# ip routing

c3850(config)# router ospf 1

c3850(config-rtr)# network 192.18.1.0 0.0.0.255 area 0
