When I ping my own router serial interface, the response time is more than when I ping the other end of the serial connection. Can I know the exact reason? I am using HDLC as encapsulation on the serial links?
When you ping your local interface on a ptp link your router will actually send the icmp echo request across the link and the remote router will redirect this echo-reply back to the sender. This redirect seems to take a bit longer than a direct reply (icmp echo-reply). If you'd like to test this you can do a debug ip packet (ON A TEST ROUTER) on the remote side and you'll see something like this.
On remote: (debug ip packet)
5w2d: IP: s=184.108.40.206 (Serial0/1), d=220.127.116.11 (Serial0/1), len 100, redirected
5w2d: ICMP: redirect sent to 18.104.22.168 for dest 22.214.171.124, use gw 126.96.36.199
Hi Don ,I had the similar problem as the sol u have given .Still I am not clear why doenot show show ip redirects that packet has been redirected.Moreover do only first packet gets redirected or all the packets get redirected.I know its only first..But why doesnot it shows in show ip redirects.Please clear my doubts.
For further refrence to the problem u can refer to "Some interesting thing about PING our interface " on the dec14 and comment on that part.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
