Hello! We have the following setup:
Two 1700 routers with one WIC-ADSL interface in each connected to the same ISP; the two ADSL lines are separate.
The ethernet interfaces are on the same VLAN as each other plus there is also the outside interface of a PIX firewall on the same VLAN.
All users access the internet through the firewall and then out of the routers. We have normal Active/Passive HSRP running, however the customer now wants to load balance the two ADSL circuits to maximise throughput.
The question is which is the best way to load balance please? Is it GBLP or OER or VRRP?
A concern that our tech guys are bringing up is the fact that the balancing methods are based on MAC addresses, and since there is only internal device (i.e. the PIX firewall) there may be difficulty balancing the load since the PIX will only look at one router.
Can anyone shed light on this for me please? Which is the best method of load balancing?
