Troubleshooting IBM 10-247
CIP: Host Running Routed Has No Routes
Possible Problem Solution
RIP not properly
configured on the
router
Step 1 Use the show running-config privileged exec command to view the router
configuration. Make sure RIP is configured on the router. If RIP is not configured,
configure it.
Step 2 Check the configuration to see whether there are network statements for each of the
networks that should be advertised in RIP updates. If they are missing, add them to
the configuration.
Step 3 Make sure the passive-interface command is not configured on the channel
interface.
Step 4 If the command is present, remove it using the no passive-interface router
configuration command.
Step 5 Make sure there are no distribute-list statements filtering RIP routing updates.
Step 6 Check the router configuration to be sure the broadcast keyword has been specified
in the claw interface configuration command. The following is the claw command
syntax:
claw path device-address ip-address host-name device-name
host-app device-app [ broadcast ]
Example:
The following example shows how to enable IBM channel-attach routing on the CIP
port 0, which is supporting a directly connected ESCON channel:
interface channel 3/0
ip address 198.92.0.1 255.255.255.0
claw 0100 00 198.92.0.21 CISCOVM EVAL TCPIP TCPIP
Step 7
If there is no broadcast keyword specified, add it to the configuration.
Host misconfiguration
Step 1 Use the netstat gate command on the host. Check whether there are routes learned
from RIP updates.
Step 2 If you do not see RIP routes, verify that the host connection is active by pinging the
host IP address from the router.
Step 3 If the ping is unsuccessful, see the section “CIP: Router Cannot ping Host or Host
Cannot ping Router” earlier in this chapter.
Step 4 Verify that the routed daemon is running on the host.
Step 5 Use the show extended channel slot/port stat exec command to see whether RIP
routing updates are incrementing the counters.
Step 6 Check the TCP/IP profile on the host to be sure that there are
BSDROUTINGPARMS instead of GATEWAY statements.
