Note: This applies to both standard and large communities alike, as well as IPv4 and IPv6. Please make sure to fix them all.
In VyOS 1.4 and 1.5, the "old" way of looking at large communities and communities is like so:
vyos@cr01-vyos# run show ip bgp large-community-info Address Refcnt Large-community [0x558fae073930] (279) 4242420696:100:1 [0x558fae116340] (32) 4242420696:10:1 [0x558fae098ad0] (12) 4242420696:10:2 vyos@cr01-vyos# run show ip bgp community-info Address Refcnt Community [0x558fae0a8d90] (14) blackhole
The "new" way is supposed to be under show bgp ipv4 ..., and some of the command completions exist but it does not work:
vyos@cr01-vyos:~$ show bgp ipv4 large-community-info % Unknown command: show bgp ipv4 large-community-info vyos@cr01-vyos:~$ show bgp ipv4 large-community-info Possible completions: <Enter> Execute the current command bestpath Display only the bestpath longer-prefixes Display route and more specific routes multipath Display only multipaths vyos@cr01-vyos:~$ show bgp ipv4 large-community-info bestpath % Unknown command: show bgp ipv4 large-community-info bestpath vyos@cr01-vyos# run show bgp ipv4 Possible completions: <Enter> Execute the current command <x.x.x.x> Network in the BGP routing table to display <x.x.x.x/x> <h:h:h:h:h:h:h:h> <h:h:h:h:h:h:h:h/x> community Display routes matching the community community-list Display routes matching the community-list dampening Display detailed information about dampening filter-list Display routes conforming to the filter-list flowspec Flowspec Address Family modifier large-community Show BGP routes matching the specified large-communities large-community-list Display routes matching the large-community-list neighbors Detailed information on TCP and BGP neighbor connections prefix-list Display routes conforming to the prefix-list regexp Display routes matching the AS path regular expression route-map Show BGP routes matching the specified route map statistics RIB advertisement statistics summary Summary of BGP neighbor status vpn VPN Address Family modifier wide Increase table width for longer prefixes
