Subject: lotsa ICMP redirects lateley??

I've been seeing (and dropping) quite a few router redirects lateley.  These
seem to be coming from about 4 or 5 different sites/routers.  The part I don't
get is why would a router legitimately send an icmp redirect to another router
many hops away??

I can't see how an icmp redirect is useful to any router except the one that
just sent the packet, and that being, why would a router send icmp redirects
many hops away??
