Hello Group

In the absense of tools such as Ciscoworks or 3rd party tools in THE LAB,
has anyone come up with a quick way of testing interface reachability for
all interfaces of all routers. (and no I do not trust myself to read each
line of the sh ip route output under pressure.)

My thoughts were to create a series of ping statements for each interface.
(This can be done quickly by copying all the configs together, sorting them
alphabetically grabing the ip address statements and changing them to ping
statements) ie.
ping 128.200.1.1
ping 133.10.0.1
ping 133.10.0.2
ping 133.10.0.3
ping 133.10.0.4
ping 133.10.0.5
ping 133.10.0.6
ping 133.10.10.1
ping 133.10.20.1
ping 133.10.20.10
ping 133.10.30.1
ping 133.10.40.1
ping 133.10.60.1
ping 133.10.60.3
ping 133.10.60.4
ping 133.10.70.1
ping 133.10.80.1
ping 133.10.90.1
ping 133.10.90.2
ping 133.200.0.26
ping 133.200.0.36
ping 133.200.0.62
ping 133.200.0.63
ping 160.100.1.1
ping 160.100.1.254
ping 160.100.100.1
ping 160.100.128.1
ping 160.100.129.1
ping 160.100.130.1
ping 160.100.2.1
ping 160.100.2.254
ping 161.100.1.1
ping 172.16.30.2
ping 172.16.30.22
ping 172.16.30.3
ping 172.16.30.6
ping 192.168.1.1
ping 192.190.100.1
ping 192.190.101.1
ping 192.190.102.1

but if I try to do a copy/paste to the router via either a console session
or a telnet session buffer overflow results and characters are dropped.
Hence this approach as is does not work. Has anyone come up with a solution
that enables reliable and quick reachability testing of all interfaces of
all routers.

thanks in advance
