Hi, Is the following configuration supported ? protocol bgp { debug { states, routes, filters, interfaces, events, packets }; debug all; ipv4 { import none; export filter export_bgp; }; local as 65001; neighbor range 0.0.0.0/0 as 65001 internal; #neighbor 10.255.254.3 as 65001 internal; password "12345678"; } If I switch to non-range neighbour everything works fins. However w/ above configuration in place the BIRD does not react to incoming packet: # tcpdump -veni any port 179 tcpdump: listening on any, link-type LINUX_SLL (Linux cooked v1), capture size 262144 bytes 19:41:05.377600 P 02:42:0a:ff:fe:03 ethertype IPv4 (0x0800), length 88: (tos 0xc0, ttl 64, id 52315, offset 0, flags [DF], proto TCP (6), length 72) 10.255.254.3.35894 > 10.255.254.1.179: Flags [S], cksum 0x123e (incorrect -> 0xb691), seq 307422819, win 64240, options [nop,nop,md5 shared secret not supplied with -M, can't check - ee89cc98bcbc5b38f7500c2f751a7612,mss 1460,nop,nop,sackOK,nop,wscale 7], length 0 However at the same time stracing the BIRD process shows nothing: # strace -p 8042 strace: Process 8042 attached restart_syscall(<... resuming interrupted read ...>) = 0 poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLOUT}], 3, 3000) = 0 (Timeout) poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLOUT}], 3, 3000) = 0 (Timeout) poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLOUT}], 3, 3000) = 0 (Timeout) poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLOUT}], 3, 3000) = 0 (Timeout) poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLOUT}], 3, 3000) = 0 (Timeout) Am I missing something? The BIRD logs are empty. Best regards, Adam
