Hi Tarry,
with standard ping it takes the ip of the outgoing interface as source
address. with extended ping you can specify which ip to use:
opcore#ping
Protocol [ip]:
Target IP address: 192.168.1.1
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Default Ping takes the address of the outbound port on your router. Default
being "ping xxx.yyy.zzz.abc"
If you just type "ping" (enter) then in the dialog that follows you can
specify the source address.

Hope someone can enlighten me on the preceding issue. Recently I

I have two routers, 3640 and 1602 both with T1 WIC's w/built in DSU/CSU.
They are connected back to back. The 3640 int s1/1 ip address is
12.10.2.97/29 and the 1602 is 12.10.2.98/29. I can ping from the 1602 both

Clearly ICMP protocol is enabled if you can ping server 1. It would seem

It appears there is some pretty mean congestion somewhere in the path
looking at the pings and its causing some packet loss. Notice the
extremely high ping times. I would first do a traceroute to www.cisco.com
and see if you can find a congested point along the path and call your
service
nitrous.digex.net
has several different sites that youcan
do ping and traceroute from OUTSIDE your network back TO your network.

Hi,
Slow response but where. Step one check your interface to see what traffic you have at
the time, check the drops etc.
If this is ok.
Do a traceroute to discover the path taken. A traceroute might indicate where to find
a problem.
First try trace, then try a ping to the first point
Check your routing table.
You could have two routes to the same destination and one of them is not
working for some reason.

Hi all,
When I ping the loopback address the reply is much quicker than when I

Do a trace to your loopback, then a trace to your connected serial

When you ping your connected interface, the packet has to go out on the

There are probably access lists employed on the router (or intervening routers) that

I can ping from router A through various hops to router F.
Therefore the packet'knows' how to reach F - and also how to find a path
back to A by reply. However from router F I cannot ping router A.
As the ping works in the first case - ie it knows the path back from F to A
- how come

I don't think it's an error. The first packet is probably lost while the
router or switch is performing an arp request. That takes a second or two
to come back, then the pings are successful. If you ping again (immediately
after the first time when you loose one packet) you shouldn
The first PING is lost because the source system is performing an ARP
request. The ARP information, once obtained, is cached (remembered) for a
small amount of time. Successive Pings to the host should show all four
replies.
Hope this helps,

eeded for
final delivery. So- your first series of Ping packets defaults to
inverse ARP, and if properly configured, the new interface is known.

We have 2620 connected to ISDN 1004 routers. The problem

delayed pings (1200ms). How can I fix this ? It gets fixed
once I reboot 1004 router but it starts doing something
after day or week.
Is it IOS or memory issue ??

Guys,
While studying the CIT. I read that using the extended ping you can change
the data pattern (0xABCD the default) to debug data sensitivity problems on
CSU/DSUs or to detect cable-related problems such as crosstalk.
I don't understand that, did anybody tried it.
Thanks
