Troubleshooting Router Connections

" NOTE:
3-8 6400 Computer TCP/IP Client User's Guide
An IP router (gateway) usually connects two different types
of network media; for instance, Ethernet to Token Ring.
The router has at least two network interface devices
installed, each with a unique IP address, which allows you
to access another part of the network.
If a router is on your network, PCTCP.INI should list the IP
address of the router through which you can access the rest
of the network. If you are having problems accessing other
hosts on your network, it may be because of problems with
your router configuration or service.

Testing Router Configuration

Use ping IP address and specify the IP address assigned to
a router on your network segment. If you cannot reach the
router, view the router entries in PCTCP.INI and make
sure they are correct.
Though only one address is necessary, you can list a maximum of
three routers in PCTCP.INI. If the first router is disabled, the second
router on the list is used; if that one is disabled, the third is used.

Testing Router Service

You can test the router service by tracing the route of a
packet through the network by using ping, as follows:
The ping -q command traces the route of the packet
"
and lists the number of hops, the domain name (if
supported) and IP addresses of the hosts that handled
the packet, and the round trip time.
The ping -i n command follows an ICMP packet as it
"
makes its way through the network. The command
output summarizes the success (or failure) of the echo
request, the round trip time, and the packet's TTL.
