Symptoms

When running the snmpwalk utility, an error is seen similar to: Error: OID not increasing: IP-FORWARD-MIB::ipCidrRouteDest...

Impact

snmpwalk may fail or snmpd may core.

Conditions

This issue occurs on typical BIG-IQ installs with the affected versions, because of a duplicate routing table entry.

Workaround

Deleting the duplicate routing table entry will temporarily work around this issue, but the duplicate entry will be restored on the next reboot. In a bash command shell, run the "ip route" command. Examine the output to identify the two entries with the same destination network. Delete the entry that includes "metric 9" by running "ip route del <entry>", where <entry> is the line of "ip route" output that describes the entry. For example: # ip route del 172.27.64.0/24 dev eth0 scope link src 172.27.64.29 metric 9

Fix Information

BIG-IQ no longer has a duplicate routing table entry by default.
