I could have tried -questions but was afraid that is was kind of very specific. To the point: Two machines running 4.7, A and B, connected to the same switch. Both running zebra. When A is turned off, B receives A's traffic (which is normal as the switch needs to flood packets after a while): TCPdump on B: Source MAC: a router's MAC (on the same LAN) Dest. MAC: A's MAC Source IP: someplace in the net Dest. IP: A's IP To my surprise B tries to forwards the packet to A, which AFAIK shouldn't because it doesn't have the right destination MAC. Of course there is no VRRP or anything else. Is this a known behavior? Would it be Zebra? Thanks in advance for any help! Fernando.
