REP & STP ISSUE

[kamleshkatariya1994]

3 switches are connected in Ring and by default spanning tree block 1 port.. I have enable REP(RESILIENT ETHERNET PROTOCOL) as I execute command "rep segment 1" on each connected interface, it shows a message that ENABLING REP , disable spanning tree on particular port.. But as I check by  "show spanning-tree" command all the REP interface still showing in spanning tree.

How to solve plz help me......

     >Spanning Tree Protocol Interaction
            REP does not interact with STP or with Flex Links but can coexist with both of them. A port that belongs to
            a segment is removed from spanning tree control, and STP BPDUs are not accepted or sent from segment
            ports. Therefore, STP cannot run on a segment.
            To migrate from an STP ring configuration to a REP segment configuration, begin by configuring a single
            port in the ring as part of the segment and continue by configuring contiguous ports to minimize the number
           of segments. Each segment always contains a blocked port,so multiple segments mean multiple blocked ports
           and a potential loss of connectivity. You can configure the edge ports when the segment has been configured
           in both directions up to the location of the edge ports

you can use stp bpdu filter under each interface, this disable STP
but friend I answer you in other post about your exact issue here can you check it and reply
