For an aggregation pair serving as HSRP gateway for downstream L2 access switches, is there any advantage of using trunk between the aggregation pair than simply a L3 link?
If vPC is used, a trunk is somewhat justified because vPC requires the trunk for peer link. But without vPC why not just put links between aggregation pair into a L3 bundle for simplicity and visibility? As I understand per port per VLAN traffic stats is not available on any platform.
