If your supervisor card supports it, VSS or Easy VSS.

Hi,

HSRP, if you're not comfortable with VSS technology.

You may look for GLBP for better load sharing but simply little complex & hard to troublsehoot if the things don't go as they supposed to do.

Also, by configuring multiple HSRP group, you share the traffic load pretty much in the similar way.

Hi,

The ideal situation is to use these 4507s as a core switch for your LAN and use another two routers for ISP connection.

However, there's nothing stopping you to use the two 4507s for both LAN core and WAN edge.

HSRP (not HRRP :-) ) has similar feature with VRRP whilst VRRP is an open protocol. There's nothing stopping you to use VRRP in Cisco environment either.

GLBP however, is an Cisco pro protocol with added load-balancing.

Now, it all comes with how you would do your WAN Edge. If your WAN edge is capable of doing load-balancing then GLBP is a good choice here. (Note. You can also use HSRP/VRRP for WAN edge load-balancing but it's pretty much defeat the purpose)

If your WAN Edge only support failover, then either HSRP or VRRP will do the job.

If you have to choose between HSRP or VRRP? Does not really matter anymore here, but if you insist, you can use HSRP over VRRP for the obivous reason.

and Leo Laohoo is right, if you can afford VSS, go for this feature. You will pretty much 'stack' your 4507 to be one single logical switch.

HTH,

Actually we are having two WAN connection terminated to our edge ,so how do i identify or know that it supports for failover and load balancing?

failover----if the primary fails then all state connection will be switched to secondary connection

load balancing--- actively shares wan traffic

am i right?

we only configure that failover or loadsharing,is it?
