PE Router 3 (PE3)

PE3 connects to customer A.

On customer A VRF5 configure:

• RD – 1:12
• Route target – export 1:10 and import 1:1 and 1:10

In the global VRF (using L3 Tunneling):

• Configure a loopback interface for each L3 tunnel to be used as the tunnel source interface, specifying the global VRF BGP address as secondary
• Configure L3 tunnels 2 (tun.0.2) connecting PE3 and PE1 and L3 tunnel 3 (tun.0.3) connecting PE3 and PE2
• Configure a static route to the loopback interface BGP address to force BGP traffic to use the tunnel instead of the associated VLAN
• Enable the VPNV4 address family in BGP configuration mode (if using IPv6 enable VPNV6)
• Activate VPNV4 neighbors
• Redistribute OSPF in the BGP configuration mode IPv4 address family for both VRF3 and VRF5

In the global VRF (using Native MPLS):

• Enable Native MPLS for the appropriate IP address type
• Enable MPLS LDP for the appropriate IP address type
• Configure a loopback interface specifying the global VRF BGP address as primary
• Enable the VPNV4 address family in BGP configuration mode (if using IPv6 enable VPNV6)
• Activate VPNV4 neighbors
• Redistribute OSPF in the BGP configuration mode IPv4 address family for both VRF1 and VRF2
