Are you sure?
I'm not really familiar with the routing code in the current kernel, so someone may yet correct me. However, judging from the 2.0.24 source, recent kernels *only* store ICMP redirects in the route cache, not in the routing tables.
As far as I know, there's no standard utility to view the route cache, but you can "cat /proc/net/rt_cache". Any routes with the RTF_DYNAMIC bit (0x10) set in "flags" are the result of a redirect.
Even though these entries won't appear in the routing table, they'll still be used.
