About IEEE 802.1ad

Below, Sx is a simple bridge without STP.

Physical network

NOTE

It is critical for L2PF to disable STP on the client CVLAN to operate in that CVLAN.

STP wins over L2PF when both are enabled on a given client CVLAN.

Table 41

displays the Port

configuration for IEEE 802.1ah and IEEE 802.1ad.

NOTE

The behavior of L2PF is independent on whether the STP in the provider SVLAN is enabled or not.
