Hello everyone,I use a pure BGP network to form internal routes (because I want to keep the as-path), and the ASN of each router is the same. The vserver of LL_IX successfully export the route bird> show route for 2602:feda:ab2::/48 export HOME_1_ARCH Table master6: 2602:feda:ab2::/48 unreachable [BGP_Prefix 11:52:02.569] (200) But the server at my home could not import it,even i change to import all; bird> show route for 2602:feda:ab2::/48 protocol LL_IX bird> show route for 2602:feda:ab2:: protocol LL_IX bird> This is the code on home server template bgp tpl_ibgp { local as LOCAL_ASN; rr client; direct; ipv6 { next hop self; import all; # import filter { # if is_bogon_asn() then { # print "is bogon asn", net, " for ASN ", bgp_path.last; # reject; # } # if is_bogon_prefix() then { # print "is bogon prefix", net, " for ASN ", bgp_path.last; # reject; # } # if my_opt_prefix() then bgp_path.prepend(LOCAL_ASN); # accept; # }; export filter { if my_opt_prefix() then bgp_path.prepend(LOCAL_ASN); if bgp_export_all() then accept; reject; }; }; } And the log Jul 28 12:16:38 archlinux bird[71587]: Kernel dropped some netlink messages, will resync on next scan.

And the vserver at ll_ix.and log on this server is just about rpki. template bgp tpl_ibgp { local as LOCAL_ASN; rr client; direct; ipv6 { next hop self; # import all; import filter { if is_bogon_asn() then { print "is bogon asn", net, " for ASN ", bgp_path.last; reject; } if is_bogon_prefix() then { print "is bogon prefix", net, " for ASN ", bgp_path.last; reject; } if my_opt_prefix() then bgp_path.prepend(LOCAL_ASN); accept; }; export filter { if my_opt_prefix() then bgp_path.prepend(LOCAL_ASN); if bgp_export_all() then accept; reject; }; }; } Under what circumstances BGP import will only be "ignored? "I think this is the problem. Could soamone help me ? thanks.
