RE: X25 ping own serial interface

I'm not too sure which bits of the config you've missed out - is
172.16.10.2 the remote ip address or your local address? Anyway, making
a few assumptions, this is how to do it.

The basic technique is to bounce the packet off a remote host, there is
no way to ping your own interface directly. There is also the problem
that by default you can only have one vc per protocol between two hosts,
and using this method requires 2 vcs - one for the outbound trip and one
for the return! This can be changed with the nvc command. So......

Assuming:
local ip address 172.16.10.1 /24
a remote ip address 172.16.10.2 /24
local x25 address 1234
x25 address of remote site 5678

The config would be:

int s0
ip address 172.16.10.1 255.255.255.0
x25 address 1234
x25 map ip 172.16.10.2 5678 broadcast
x25 map ip 172.16.10.1 5678 broadcast
x25 nvc 2

with appropriate coding of nvc and maps at the remote host. A ping to
172.16.10.1 would then be sent via 172.16.10.2 and would work!

Hope this helps.

Vaughan

Subject: X25 ping own serial interface

Hi...

How can I configure x25 so that I can ping my own serial interface.
I can ping the remote interface, but not my own.

I have tried

int s0
x25 address 5678
x25 map ip 172.16.10.2 5678 broadcast

but it doesn't work

Any hints ??

Eng Wee
