I've been trying to make sense of the docs when it comes to configuring RSTP in a simple way and in a more or less simple topology. (On older/EOS systems: do nothing at all besides activating it, if it is not running by default)
Page 1102 of EXOS 22.4 User Guide shows an RSTP setup apparently defining a carrier VLAN. However, page 1056 (in the introduction part to Spanning Tree Domains and carrier/protected VLANs), RSTP is not mentioned in the list of STP protocols requiring a carrier VLAN.
I also found the following, which does indeed look simple: https://extremeportal.force.com/ExtrArticleDetail?an=000080794
Is using the default "Default" VLAN (VLAN 1) everywhere a prerequisite for the knowledgebase article to work? If so, what would be the actual steps to have EXOS RSTP interoperate in the following way with 3rd party switches running "port-based" RSTP:
Is also found this: https://extremeportal.force.com/ExtrArticleDetail?an=000079923
When we set up the 3rd party stuff we used RSTP because we didn't want all the fuzz with MSTP and regions and instances etc. anymore, which we didn't use anyway. Now you'll probably be telling me that MSTP is easier to set up than RSTP. Is that info still valid? Argh (Unfortunately the KB articles give no indication as to when they were created or last updated)
BTW most examples create an STP domain s1, while I guess we should just go and redefine s0?
PS. Why is it that "An STPD with multiple VLANs must contain only VLANs that belong to the same virtual router" ?
