PE Router 3 (PE3)

PE3 connects to customer A.

In executive command mode, configure SPBV on the router:

• Set Spanning Tree version to SPT
• Configure the Spanning Tree MST configuration name to spbvRegion1
• Configure the SPVID pool for 2000 - 2200 and set the pool to SID spvid (4095)
• Map customer VLAN 100 to SID spbv (4093)
• For the ECT algorithm, there is only a single SPBV region, so the default value of 1 is used.
• All Global router ports, ge.1.10-20 are enabled for SPBV

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
