Description (partial)

If there is situation of ICMP redirect, the packet is sent to CPU for sending ICMP-redirect message back to the host. The original packet will still go out. If this outgoing interface also has egress span source configured, then SPAN will not work.

Egress span source is configured on the same interface where packet goes which triggers an ICMP redirect.
