Below, Sx is a simple bridge without STP.
FIGURE 28 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.
