SMF 2. The tree root is a switch within the network elected by the STA spanning-tree algorithm to use when computing the best path between bridges throughout the network and the root bridge. Political Posts. The routing instance type can be either virtual-switch or layer2-control. For now you have the mess - every switch a root bridge. You can also enable BPDU root protection for all spanning-tree protocol instances on the interface. If a BPDU packet is received for an edge port, the port becomes a nonedge port. The VLANs are associated with specific interfaces on each of the four switches.

  • Multiple Spanning Tree Protocol (MSTP) maps multiple VLANs into a spanning tree instance, with each instance having a spanning tree topology independent of other spanning tree instances. Juniper Networks devices provide Layer 2 loop prevention through Spanning Tree Protocol (STP. components: Junos OS Release for the QFX switches; Four QFX switches or physical interfaces. This example shows MSTP configured on logical interfaces.

    Table 1: Topology for Configuring MSTP on the QFX Series. can i run both MSTP and RTG on the EX switch configured in a vurtual chassis. regards. Tayyab Model: ext. On an EX the disbled port is show as disabled as the case below for ge-0/0/ What is the.
    Verify the MST interface configuration. We expect our members to treat each other as fellow professionals. I'm not entirely sure that I'm understanding the issue with the All advice welcome.

    That's a very interesting issue Ended up running rstp and VSTP like suggested and setting the bridge priority of the juniper to lower than all other devices to ensure it's the root.

    1. The spanning-tree interface parameters for instance 2 show that both ports are designated ports, which means Switch 2 is the root bridge for this instance.
