Application of RRPP and STP

RRPP cannot be configured with STP/RSTP/MSTP on the same interface at the same time, but you can configure RRPP and STP on different interfaces of a device. Figure 1 shows an example of a network that has RRPP and STP configured on different interfaces of the same device.

Figure 1 Network of RRPP and STP

In Figure 1, RRPP is applied to an Ethernet network enabled with STP/RSTP/MSTP in tangent mode. You can enable RRPP and STP/RSTP/MSTP on different interfaces of the intersecting device (UPE1) so that the RRPP network and the STP/RSTP/MSTP network are used together.
