Hi,
I am trying to configure a router : to load balence between Serial and ISDN lines. Both are 64Kbps speed. Can you suggest which method is best for this (cisco 2600 router)?
I tried all four load-sharing approaches:
- fast switching (ip route-cache)
- process switching (no ip route-cache)
- CEF (per-destination)
- CEF (per-packet)
Out of all, fast swtiching seems to be better. But, I noticed that, performance even with this not good (however better than other load-sharing methods). Most of the traffic is taking ISDN line rather than Serial line. I have two static routes: ip route 0.0.0.0/0 Serial0/0 ip route 0.0.0.0/0 Dialer1
