Configuring MPLS Layer-2 VPNs

Configuration Example

The MPLS TLS ESRP configuration example, shown in Figure 7-7, illustrates how to
configure a pair of BlackDiamond switches to provide redundant Layer-2 VPN services
over an MPLS domain. Two additional switches have been added to the TLS MPLS
network configuration example shown in Figure 7-1, LSR 5 and LSR 6. LSR 5 and LSR 6
provide redundant connectivity for TLS VLANs into the MPLS domain.
