Hi, I've configured a dummy interface (in Linux) with IP Address 1.1.1.1/32 and advertising it in BGP. However, this network is not getting advertised unless I also give "no bgp network import-check" command. Please see below for more details and advise what could be going wrong or I'm missing some other configuration. (Same is true with IPv6 address with /128 prefix - this also cannot be advertised unless no import-check is given even though the address present in IPv6 routing table) Thanks Amol Current configuration: ! frr version 7.4 frr defaults traditional hostname FRR log syslog ! router bgp 1 no bgp ebgp-requires-policy neighbor 10.10.10.2 remote-as 2 ! address-family ipv4 unicast network 1.1.1.1/32 exit-address-family ! line vty ! end ==== FRR(config-router)# do show ip route Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP, F - PBR, f - OpenFabric, > - selected route, * - FIB route, q - queued route, r - rejected route K * 1.1.1.1/32 [0/10] is directly connected, loop0, 00:54:33 C>* 1.1.1.1/32 is directly connected, loop0, 00:54:33 === [ As you can see "*>" is missing before 1.1.1.1/32.
