Why am I not be able to ping myself ATM subinterface ip address?

I had a very strange problem. I got no successful ping respond to my router local ATM sub-interface

Two routers connect each other over the ATM/Frame WAN switch.

Router A (ATM Sub-interface:165.250.5.2)„º====„»( ATM/Frame WAN switch)„º====„»(Serial Sub-interface:165.250.5.1)Router B

I can ping IP 165.250.5.1 from router A, but I can not ping 165.250.5.2 from router A. I can ping all IP address from router B

I got debug ICMP packets form router A here: you can see the ICMP packets are redirected. So I can not get ping respond. Do you know why?

Re: Why am I not be able to ping myself ATM subinterface ip addr

Please note that unless you are using a LANE client, you will not be able to ping your own ATM interface IP address. This is normal with ATM PVC configurations
