RE: ? how cisco router handle the out-of-order ICMP echo-reply packets

There aren't sequence numbers with ICMP.  And the timeout value is
watched/triggered before the next ICMP is sent, so there shouldn't really be
any ordering problem/interpretation anyway.

Hi,

Does someone happen to know how the Cisco IOS  handle the out-of-order 
ICMP echo-reply packets? print it as success  or lose?

Thanks,

Zhao Ping
