[nv-l] mibtable hangs for ospf table on cisco

[thierry.van-mol@ciev.vd.ch]

By trying Leslie's script get_ospf_if_sh, I discovered that the script
hangs
on all my cisco routers. By trying the mibtable , I discover that it hangs
after a few "dummy" ospf entries:


# /usr/OV/bin/mibtable -table ".1.3.6.1.2.1.14.7.1" \
      -fields "ospfIfIpAddress=1:15,ospfIfAreaId=3:15,ospfIfAdminStat=5:8"
-node router1

                      User Specified MIB Table for router1

ospfIfIpAddress  ospfIfAreaId     ospfIfAdminStat
0.0.0.0          0.0.0.0          disabled
0.0.0.0          0.0.0.0          disabled
0.0.0.0          0.0.0.0          disabled




and then mibtable hangs.

If I do a snmpwalk on the node, it works OK:

# snmpwalk router1 .1.3.6.1.2.1.14.7.1

.............


The number of those "dummy" instances in the mib varies from router to
router, but there is
at least one. For example:

# /usr/OV/bin/mibtable -table ".1.3.6.1.2.1.14.7.1" \
         -fields
"ospfIfIpAddress=1:15,ospfIfAreaId=3:15,ospfIfAdminStat=5:8" -node router2

                      User Specified MIB Table for router2

ospfIfIpAddress  ospfIfAreaId     ospfIfAdminStat
0.0.0.0          0.0.0.0          disabled

then hangs...


#snmpwalk router2 .1.3.6.1.2.1.14.7.1

Any ideas?
Thanks.
