The following configuration guidelines for the use of split horizon group in a VPLS service apply:
On 7210 SAS-T, and 7210 SAS-Sx/S 1/10GE operating in network mode, mesh SDPs cannot be configured in a service which uses split horizon group (SHG). Conversely, if a service has a mesh SDP configured, split horizon group cannot be used in the same service.
On 7210 SAS-Mxp, service based SHG can be configured along with mesh SDPs and spoke-SDPs.
