Solved: "subnets" keyword into redistribution have disappear from the config!

JEROME BOSC · ‎03-15-2022

Hello,

I just noticed the "subnets" keyword from redistribution into OSPF isn't displayed anymore from the config.

I am using IOS-XE 16.12.5 on a ISR4331.

(config-router)#router ospf 1 vrf TXX
(config-router)# redistribute bgp 65444 subnets




sh run | s ospf gives : 

router ospf 101 vrf T01
redistribute bgp 1031

No more subnets keyword displayed, but fortunately, subnets are advertised !

Maybe it has become implicit ?

Have you noticed it ? Is it discribed somewhere on the Cisco Website ?

Regards - Jerome

OK thanks for your answer. I made some tests on an IOS (on an 2900 router running the last IOS available) and it looks like it is the default behavior as well. The only difference is you can see it in the sh running on IOS device, whereas it is hidden in the sh running on an IOS-XE device.

Hello

Its applied by default in IOS-XE so subnetted prefixes are advertised if you want ot advertise just classful prefixes then you need to specify it
