I have a few questions on load balancing OUTGOING internet traffic through the ASA5540 firewall running code version 7.2. My company has 2 internet links going to the same ISP and the firewalls are running in active/standby mode. I would like to load balance OUTGOING internet traffic through 2 different edge routers. The outside interface of the firewall and the internal interface of both edge routers are on the same subnet. Here's a quick diagram of
---------------->Router A -->internet connection A, same ISP as B
---------------->Router B -->internet connection B, same ISP as A
1. Can I use 2 static routes on the ASA5540 to do outgoing load balancing? If so, is there a way to configure the firewall to track internet link failure.
2. Code 7.x supports OSPF and RIP. If I use OSPF, is it recommended to inject a default route through both edge routers into my internal network to do load balancing?
3. What is the recommended way to configure outgoing load balancing with dual internet links going to the same ISP.
..NO !! GLBP is not a feasible solution here..Gateway Load Balancing Protocol feature provides automatic router backup for IP hosts configured with a single default gateway on an IEEE 802.3 LAN....just like VRRP/HSRP..moreover not supported on 1800 series
we are not looking for router backup failure...we are looking for load sharing rather
