My apologies if this question has already been asked, I wasn't able to find an answer.
I'm currently studying for my DCCOR and I'm using CML to play with Spanning-tree on some Cisco 9Ks.
When I check for inconsistentports, I see that bridge assurance inconsistencies for specific VLANs. The VLANs impact will be ones that are missing from one of the 3 switches.
My question(s) is, are their scenarios where seeing this is OK, and can be ignored?
I have 3 9Ks connected in a triangle, with one of them (9K-3) is connected to a router. The router connection port is in a VLAN, and an SVI is configured with a /30. Both downstream 9Ks do not have VLAN 100 configured. 9K-1 shows Bridge Assurance Inconsistent for VLAN100.
Another instance I see this is on 9K-1 and 9K-2. They have a VPC configured for VLAN10 which is intended to be used for servers connect to 9K-1 and 9k-2. I don't plan to add devices connected to 9K-3 to VLAN10, so its not configured, but the VLAN is showing inconsistent on 9K-1 and 9K-2.
Is this OK to ignore? Are there configuration best practices I should be following? Should I be configuring something for VLANs they may not be sent to all devices?
