Currently I run 2 routers(7206) and a core switch(6509 acting as a vlan router/switch), BGP to two different providers and EIGRP internally. The 2 routers run HSRP and the switch points to a HSRP as the gateway.
Currently R1 is the primary router all traffic goes out 1 router. The other router was for backup in case the pri link went down. We are soon going to have to equal providers and I want to balance the traffic over both of them with BGP.
Is my thinking wrong that I would be better off using GLBP between the routers to accomplish this over HSRP?
I currently do not redistribute BGP to EIGRP but I have recently upgraded my 6509 with sup 720's so I know it could handle it. I am just not sure whether or not to use a high availability protocol or just let the routing protocols handle the switch over. In my mind GLBP would provide better uptime in case one or the other links goes down. But thats why I am asking as I could be very wrong.
Any help would be greatly appreciated.
