I have a router with a simple babel protocol announced on an interface: protocol babel babel { interface "eth2" { next hop prefer ipv6; }; ipv4 { export where net ~ [0.0.0.0/0]; import none; }; ipv6 { export where net ~ [::/0]; import none; }; randomize router id; } bird> show proto babel Name Proto Table State Since Info babel Babel --- up 17:32:00.497 Out of interest, I tried the 'show babel' commands, but couldn't work out the syntax: bird> show babel ? show babel interfaces [<name>] ["<interface>"] Show information about Babel interfaces show babel neighbors [<name>] ["<interface>"] Show information about Babel neighbors show babel entries [<name>] Show information about Babel prefix entries show babel routes [<name>] Show information about Babel route entries bird> show babel interfaces "eth2" syntax error, unexpected CF_SYM_KNOWN bird> show babel interfaces babel syntax error, unexpected CF_SYM_KNOWN bird> show babel routes babel syntax error, unexpected CF_SYM_KNOWN What would be a correct argument to supply to these commands? In case it's relevant, I'm running 2.17.1 on Linux, which is the latest 2.x version on https://bird.network.cz/ https://bird.network.cz/download/ although I've just spotted there was a 2.17.2 announced on the mailing list in September. Best wishes, Chris.
