I am trying to understand the "Adjacency type (L2 or L3)" setting for service graph connectors.
Figure 21 on the following white paper show some information about this.
https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-734298.html
It says
1) "If the connector is associated with a bridge domain that provides the Layer 3 outside (L3Out) interface function, in addition to verifying that the unicast routing option is set to true, you need to make sure that the adjacency is set to Layer 3, not Layer 2"
question - what does it mean - "bridge domain that provides the Layer 3 outside (L3Out) interface function”?
2) To Help Ensure That the Switch Virtual Interface Is Enabled on the Bridge Domain with L3Out, Set Adjacency to Layer 3
question - what does it mean - "Bridge Domain with L3Out”?
So, in addition to my main question regarding the Adjacency type setting for Service graph, I now have 2 more questions
please help me to under these things
