Cisco Nexus 7010 (PE device):

1. Enable the various NX-OS feature sets required for L3 VPNs:

Nexus7010# configure terminal

Nexus7010(config)# feature ospf

Nexus7010(config)# feature /jointfilesconvert/492162/bgp

Nexus7010(config)# feature mpls l3vpn

Nexus7010(config)# feature mpls ldp

2. Define a loopback interface and configure an IP address for that interface. This address

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

Nexus7010(config)# interface loopback0

Nexus7010(config-int)# ip address 192.18.69.1/32

Nexus7010(config-int)# no shutdown

Note that an explicit no shutdown command is mandatory for Cisco Nexus 7000

devices.

3. Define IP addresses for interfaces e3/10 (connected to the Juniper MX80 acting as a P

device) and e3/3 (connected to the Juniper Virtual Chassis Fabric):

Nexus7010(config-int)# interface e3/10

Nexus7010(config-int)# description to Juniper MX80 P device int xe-0/0/2

Nexus7010(config-int)# ip address 192.18.70.1/24

Nexus7010(config-int)# no shutdown

Nexus7010(config-int)# interface e3/3

Nexus7010(config-int)# description to Juniper Virtual Chassis Fabric

Nexus7010(config-int)# ip address 192.18.68.1/24

Nexus7010(config-int)# no shutdown

Nexus7010(config-int)# exit

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

Nexus7010(config)# mpls ldp configuration

Nexus7010(config-mpls)# router-id Eth3/10

Nexus7010(config-mpls)# neighbor 192.18.38.1 targeted

Nexus7010(config-mpls)# exit

5. Enable MPLS on interface e3/10 (connected to the P device):

Nexus7010(config)# interface e3/10

Nexus7010(config-int)# mpls ip

Nexus7010(config-int)# exit

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

Nexus7010(config)# router ospf 1

Nexus7010(config-rtr)# router-id 192.18.69.1

1 2 ... 20 21 22 23 24 25 26 27 28 29 30 ... 82 83
