Performing load balancing this way is very unpredictable. When you do this
within your own network (ie. intra-as) you have full control and knowledge
over the possible paths. Though this will work, performance will vary, and
potentially fail if one of the providers goes down.

Hi,

I would like to know if a default routing for multiple providers works as a
basic solution for Multi-Homing.

The customer has a low-end router and the step 1 would be add default routes
in the way to both increase outbound bandwidth to the Internet and
redundancy that multi-homing provides.

The configuration would be something like:

ip route 0.0.0.0 0.0.0.0 @provider1
ip route 0.0.0.0 0.0.0.0 @provider2

int s0
ip route-cache
int s1
ip route-cache

Having two default routes with equal metric, both routes will be installed
in the Cisco´s IP routing table and the load balancing would be done on a
per-connection basis.

Is this the right way to do that ?

I would like to know about your experience with this kind of solution.

Best Regards,
