This command was removed from Quagga five years ago and never made it to FRR.

This is not a "bug" - we pass any argument to show ip bgp down to FRR.

Probably the implementation should be changed and remove the /opt/vyatta/share/vyatta-op/templates/show/ip/bgp/node.tag/ directory which is responsible for this and add possible missing show commands to the CLI

[email protected]:~$ show ip bgp scan
% Unknown command: show ip bgp scan
[email protected]:~$ show ip bgp foo
% Unknown command: show ip bgp foo

@Viacheslav what you think?

erkin added a comment.EditedAug 29 2020, 3:46 AM

Viacheslav seems to have migrated a good portion of Quagga show commands to the XML template format a while ago and the remaining completion file for ip bgp scan also got deleted then. I can see that the useless command completion for it is still there on 1.2.5 LTS but it's gone from the nightly builds.

I have removed show ip bgp scan for the upcoming 1.2.6 release.

@erkin it looks like the same applies to:

[email protected]:~$ show ip bgp rsclient summary
% Unknown command: show ip bgp rsclient summary

can you verify this?

Yup, the same situation: It's there on LTS but not on nightly. Also nonexistent functionality on frr, so it can go from the completions too. (Although the CLI files are still in the vyatta-op-quagga repo.)
However it still seems to be stuck in reset on nightly:

$ reset ip bgp foo rsclient
% Unknown command:  clear ip bgp foo rsclient
