Building A & B, Ethernet connection from 6509 -àASA à ISP router has no
From 6509 in Bldg A & B. I added statement below to direct Internet traffic to both ASA
ip route 0.0.0.0 0.0.0.0 10.20.30.1
ip route 0.0.0.0 0.0.0.0 10.20.40.1
In theory, this should work.
The goal is to have a design that does load-balancing and fail-over for the Internet traffic.
The question I have is, how I make this set up for fail over without spending lots of $$$.
If you want to have more control over it, you can use the static route tied to an sla tracker. Here's a quick example:
ip sla 1
ip sla schedule 1 life forever start-time now
track 1 rtr 1
delay down 10 up 20
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/2.210 track 1
This will insert the route only when the ip address is reachable with a ping, and you can adjust the delay down and up timers.
Hope this helps
