VPLS Packet Walkthrough in Network Mode
This section provides an example of VPLS processing of a customer packet sent across the
network from site-A, which is connected to PE-Router-A through a 7210 SAS M to site-C, which
is connected through 7210 SAS M to PE-Router-C (Figure 35) in an HVPLS configuration. This
section does not discuss the processing on the PE routers, but only on 7210 SAS routers.
