Hello, as Ondrej mentioned already, you have wrong basic network setup - you're using wrong network masks. H0 thinks, that all nodes (H1, H2, H3) ale in single directly-connected L2 network. To have BGP working, you need to have basic L3 connectivity working - that means, you must be able to ping

Hello, that's expected behavior of BGP. There's extension to BGP described in RFC 7911 allowing multiple paths to be advertised to eBGP peers, in Bird you can try "add paths" configuration option (but this also requires capabality support on other side). With regards, Daniel On 8/21/18 12:05 PM,

Hello, I think sorting should not be limited only to "show routes" output. Also other show commands needs to be sorted in human-readable order (like show protocols, show bfd sessions etc).

Hi, in general is good practice to null-route packet with unused destination IP for address space assigned to your network. That's done by statement you sent. You can define multiple protocols in config file, including static one (typically definition is based on it's purpose). - Daniel On 12/3/
