CSCve91311 - OSPF Area Range Command Truncated

[ogolovatyuk]

Hi,

I have experiencing the similar issue with OSPF "summary" command on 7.0(3)I5(2) software.

------

nexus9k-01(config-router)# summary-address 100.100.100.0/24
Invalid range, host bits are set

-----

Shorter prefixes work as expected.

Does anyone  know if the latest NX-OS has a fix for "summary" command as well as for "area range" command?

The nexus is on a production network and I am not able to use it  for testing .

Regards

Alex

Hi there,

Sorry you are running into this issue. This is fixed starting in the following releases: 7.0(3)I7(1) 7.0(3)I6(2) - We just released 7.0(3)I7(3) which can be found on Cisco.com which would also contain the fix for CSCve91311 among others.

Hope that helps.

Thank you Andrea. 

 CSCve91311 bug only mentioned fix for "area range" command. There is nothing in regards of the "summary-address " command  in the bug description, that is why I am not sure that the issue with "summary-address"  has been fixed.

If you have an access to the 7.0(3)I7(1) 7.0(3)I6(2)  NX-OS , could I ask you to check if "summary-address 100.100.100.128/25" command  works? 

Thanks again.

Alex,

Sure thing - "summary-address" has certainly been fixed on I6(2) and the other releases mentioned. I'll go ahead and modify the defect to make sure we state "summary-address" is impacted by the same defect and thus fixed as well as the "area range" command to avoid confusion in the future - Appreciate you bringing this up:

Quick test on my 9K in I6(2) for both summary-address & area range:

9396-VTEP(config)# router ospf 1000
9396-VTEP(config-router)# summary-address 100.100.100.128/25
9396-VTEP(config-router)# area 1.2.3.4 range 123.123.123.0/24 cost 1
9396-VTEP(config-router)# end
9396-VTEP# sh run ospf
