1.L2 or L3 etherchannel link between the two core 6500 switches.
What is the advantage of using a L2 or L3 etherchannel link between the two core switches. What would best suite my network design (Diagram)
2.HSRP/GLBP: redundancy for Edge switches
For L2 redundancy for all edge switches I'm undecided to use GLBP or HSRP. What is the advantage\disadvantage of each protocol. What would best suite my network design? (Diagram)
Each core 6500 is attached to a single Cisco 2821 router over a L3 link. Both routers are running eigrp.
All routing will be out the primary router and the secondary router is used only for backup.
What would be the best way to configure this for failover? Should eigrp routing be enabled on the two core 6500 switch.
Etherchannel(6509 - 6509): L2 or L3 link
Redundancy(6509 - 3750): GLBP or HSRP using rapid-pvst (spanning-tree vlan 10 root primary)
