Core Switches
The following are best practices for the campus core:
Reduce the switch peering by using redundant triangle connections between
switches.
■
Use routing that provides a topology with no Layer 2 loops, which are seen in Layer 2
links using STP.
■
Use Layer 3 switches on the core that provide intelligent services that Layer 2
switches do not support.
■
Use two equal-cost paths to every destination network.
