Can you please post the relevant portions of the configurations ? I would
like to test this.

Subject: Unicast RPF check! (correction!)
Please correct the previous email as i mistakenly put R1 where it should be
R2 that has the "ip verify unicast reverse-path" config!
Hi group!
I got strange behavior and hope someone can clarify it for me.
I have the following simple topology:
R1-----------------------------------------R2--------------------------SW1
10.10.10.1 10.10.10.2 192.168.1.2 192.168.1.1
R1 is connected to R2 via Frame-Relay
R2 is connected to SW1
R2 frame-relay interface has RPF check as "ip verify unicast reverse-path "
When R1 pings SW1 interface (192.168.1.1) i get RPF failure! R2 debug shows
the 192.168.1.1 IP comes from the frame-relay interface and thus drop the
traffic as spoofed IP!
Can anyone explain what's going on?
