Hi guys

Can someone help with the following scenario:

Setup:

The client has 2 connections to 2 different ISPs & wants to establish
redundancy in case of failure to any one ISP. Can't use any dynamic routing AT
ALL (no BGP or RIP etc). Connection to ISP 1 is with a serial link router (L1)
which in turn connects to another router via Ethernet (L2). L2's 2nd Ethernet
goes into a Cat switch (S1). Connection to ISP 2 is also with another serial
link router (R1) which in turn connects to another router via Ethernet (R2).
R2's 2nd Ethernet goes into a Cat switch (S1). Into S1 we have another router
(C1). C1's 2nd Ethernet is connected to user LAN.

The Issue:

How to achieve redundancy & possible load balance with static/default routes.

So far in the lab I've tried to put 2 defaults on L1. The 2nd with higher AD
pointing to R1 but this does not seem to work. Some packets make it out R1 but
the other half fail

Please help!
