Campus ve MPLS Aglarda Spanning tree priority

Core, aggreation ve acces switchler için campus ve … ağlarda kullanılabilecek stp değerleri aşağıda ki gibidir.

Priority Description Notes
0 Core Switch For the core switch (core1.campusX)
4096 Redundant Core Switch For cases where we have a second core switch (building redundancy into the core)
8192 Reserved
12288 Building Distribution (dist1-b1.campusX; dist1-b2.campusX)
16384 Redundant Building Distribution For cases where we have a redundant building distribution switch
20480 Secondary Backbone This is for building complexes, where there are separate building (secondary) backbones that terminate at the complex backbone.
24576 Access Switches This is the normal edge-device priority (edge1-b1.campusX; edge2-b1.campusX; edge1-b2.campusX; edge2-b2.campusX)
28672 Access Switches Used for access switches that are daisy-chained from another access switch. We’re using this terminology instead of “aggregation switch” because it’s hard to define when a switch stops being an access switch and becomes an aggregation switch.
32768 Default No managed network devices should have this priority.
