"show bgp neighbors ... advertised-routes" and some other commands fail for IPv4 neighbors
Open, Requires assessmentPublicBUG

Description

When I try to get more details, like for example the advertised routes, I get an error.

[email protected]:~$ show bgp neighbors 127.0.0.1 advertised-routes
% No such neighbor or address family

This applies to all sub-functions of show bgp neighbors 127.0.0.1 ...
"show bgp neighbors 127.0.0.1" as such however, works.

[email protected]:~$ show bgp neighbors 127.0.0.1
BGP neighbor is 127.0.0.1, remote AS 1111, local AS 2222, external link
  Local Role: undefined
  Remote Role: undefined
  BGP version 4, remote router ID 127.0.0.1, local router ID 1.1.1.1
  BGP state = Established, up for 00:19:46
  Last read 00:00:00, Last write 00:00:16
.

.

Also the BGP session as such works fine,

[email protected]:~$ show bgp summary

Also the error applies only on IPv4 sessions.
IPv6 sessions work fine.

Event Timeline

use the next syntax

show bgp ipv4 neighbors x.x.x.x advertised-routes

This works,
but if this is the new syntax the cli needs some cleanup.

show bgp neighbors 127.0.0.1 advertised-routes

Is still offered by the autocomplete and works for ipv6.
