I have a network, where only Extremes exist.
Access layer are 8 stacks spread through floors.
Distribution layer is a stack of 2 X670.
Core layer are two BD8806 connected with MLAG. There is also VRRP configured.
There is one etherchannel between core for MLAG, and one etherchannel to X670 stack.
Floor stacks are connected to X670 with one etherchannel link.
I have 30 vlans total.
The schema is provided below.
Could you please help me to find the most suitable STP type/configuration?
At the moment I have configured EMISTP encapsulation with dot1w mode, but I don't like it.
Many thanks in advance,
P.S. With this scheme I have strange alternating ping replies from 1 to 50 ms. Is there any connection with STPDs or VRRP in the core?
P.P.S Could you give me a link to any article where the simplest STP configuration on extremes described? I am interested in the method of configuring STP for all vlans with minimum efforts like in CISCO.
