Hi, I have Three routers in my network like the below diagram. RTR01 has a BGP to RTR02 and RTR02 has an OSPF to RTR03. I wrote a filter to redistribute origin routes from BGP protocol to OSPF in RTR02 but it's not working. ┌───────┐ ┌───────┐ ┌─────┐ │ RTR01. ├──┤ RTR02 ├── ──┤ RTR03 │ └───────┘ └───────┘ └─────┘ 10.2.2.3 -BGP- 10.2.2.2 10.100.100.2 -OSPF- 10.100.100.3 RTR02 Bird config: protocol bgp bgp_to_rtr01{ local as 64513; neighbor 10.2.2.3 as 64512; source address 10.2.2.2; allow local as 64513; multihop; ipv4 { import all; export all; }; } protocol ospf my_ospf { rfc1583compat yes; tick 2; ecmp no; ipv4 { import where proto = "bgp_to_rtr01"; }; area 0.0.0.0 { stub no; interface "dummy0" { type ptp; }; interface "enp0s9" { type broadcast; }; }; } I did the same redistribution to OSPF to announce the default route via OSPF and it is working, but the same filter for redistribution BGP to OSPF is not.
