Example: Configuring a Remote LSP CCC over Aggregated Ethernet

See the topology in Figure 13. In this topology, CE Router G has an aggregated Ethernet connection to PE Router F. CE Router D has an aggregated Ethernet connection to PE Router E. Router E and Router F have an MPLS LSP between them. With remote CCC, you specify that the circuit from Router D is connected to the circuit from Router G. The circuit from Router D is connected to the LSP on Router E; the circuit from Router G is connected to the LSP on Router F. In other words, ae0.0 and ae1.0 are connected using lsp1-2 and lsp2-1. You configure Router D and Router G as standard aggregated Ethernet interfaces. For more information about aggregated Ethernet, see Configuring Aggregated Ethernet Interfaces.
