Hub And Spoke Tls Configuration - Extreme Networks BlackDiamond 6800 MPLS Installation And User Manual

Configuring MPLS Layer-2 VPNs

Hub and Spoke TLS Configuration

The following example, shown in Figure 7-3 , configures a four-node hub-and-spoke
MPLS TLS configuration. The hub LER MPLS configuration includes a TLS tunnel to
every other LER. Each spoke LER MPLS configuration includes a TLS tunnel to only the
hub LER. The egress VLAN for the VPN is called ncsu. The target IP address
(10.100.100.2) shown in each TLS configuration command must be either a Router ID or
Loopback VLAN interface address.
