I was reading one of the slides from this year Cisco Live regarding VPC. One particular slide kinda confused me (attached). My understanding of setting up backup route path with VPC is: Use a dedicated L3 link between the two VPC peers for dynamic routing adjacency; Use a non-VPC VLAN interface between the two peers on a layer 2 trunk to form routing adjacency; Also possible to use specific VLAN over the peer link to form adjacency.
But from the Cisco Live Slide, I am confused:
1. The four bullet points means four options? If so, What does second and third bullet points are referring? Mainly why passive-interfaces on HSRP SVI?
2. What the section on top with blue background trying to say?

1. The four bullet points means four options? If so, What does second and third bullet points are referring? Mainly why passive-interfaces on HSRP SVI?
bullet 2 is saying any user/server vlan with HSRP should be configured as passive, so there isn't multiple peering between the 2 switches. bullet 3 is saying, you can use an SVI to peer layer-3 between the 2 switches.
2. What the section on top with blue background trying to say?
That is a combination of bullet 2 and 3. Same as bullet 2 and 3.

Thanks, so they are actually lining up with my own understandings, just different representation.
