One of the conditions to generate an ICMP Redirect Message is that "the packet is being forwarded out the same physical interface that it was received from" (RFC 1812).
Therefore, we need to be able to trap such packets and let the kernel decide what to do with them.
For each RIF, enable the loop-back filter, which will raise the LBERROR trap whenever the ingress RIF equals the egress RIF.
