MadProf Posted March 29, 2022 Share Posted March 29, 2022 (edited) Hello, I am studying OSPF and I am using CML2. In my studies, all the vIOS images in CML2 do not output Routing Bit information in the output of a command: No Routing Bit R6#show ip ospf database router OSPF Router with ID (150.1.6.6) (Process ID 1) Router Link States (Area 0) LS age: 452 Options: (No TOS-capability, DC) LS Type: Router Links Link State ID: 150.1.1.1 Advertising Router: 150.1.1.1 LS Seq Number: 80000007 Checksum: 0x1391 Length: 60 Number of Links: 3 Different IOS image, R7#sho ip ospf database router OSPF Router with ID (150.1.7.7) (Process ID 1) Router Link States (Area 2) Routing Bit Set on this LSA in topology Base with MTID 0 ################################################## Routing Bit LS age: 366 Options: (No TOS-capability, DC) LS Type: Router Links Link State ID: 150.1.6.6 Advertising Router: 150.1.6.6 LS Seq Number: 80000006 Checksum: 0xF8FE Length: 36 Area Border Router AS Boundary Router Unconditional NSSA translator Number of Links: 1 I am inquiring whether anyone knows of a current image preferably vIOS that outputs Routing Bit information. Any assistance in this matter is grealtly appreciated. Edited March 29, 2022 by MadProf 1 Link to comment Share on other sites More sharing options...
w1z4rd Posted March 29, 2022 Share Posted March 29, 2022 The Routing Bit is supported on all IOS images. The Routing Bit is only set on an LSA when the router can actually use the for routing. You must troubleshoot why R6 cannot route to 150.1.1.1 Also, keep in mind that IOS sometimes does not say "Routing bit set...", but rather it will provide no information. The Routing Bit information will actually pop up afer the LSA loses it. IOS will then say "Routing Not Set for LSA ...." Link to comment Share on other sites More sharing options...
MadProf Posted March 29, 2022 Author Share Posted March 29, 2022 "The Routing Bit is supported on all IOS images." Routing Bit is NOT supported on all images and that is the reason I am here. Please refer to the Kevin Rivest reply: This is the hidden content, please Sign In or Sign Up My question is limited to whether an vIOS .qcow2 image exist that would output Routing Bit Set. I am certain that some versions of IOS/IOS-XE do not output Routing Bit. Thanks 23 4 2 Link to comment Share on other sites More sharing options...
