Hi, group:

  I want somebody to help me on the command. You see, I set idle-timeout 20 and made a big PING.
So the 2-way traffice exist, I think the link is not IDLE. but at the 01:00:21 the DDR disconnect the call. Why?

TIA

=== Test one ===

r1#p 172.16.12.2 rep 1000 size 500

Type escape sequence to abort.
Sending 1000, 500-byte ICMP Echos to 172.16.12.2, timeout is 2 seconds:
...

( At the same time, back to R2, made a PING to bring up the link )

( Make a telnet session from R2 to R1, then 2-way traffic exist. But it disconnect after 20 second )
