Please ignore this. A typo in iptables... On 08/18/2017 01:43 PM, Jerry Scharf wrote:

Hi,

I'm confused with what is going on with this.

Here are the config snippets for what I am doing:

this sets up the bgp peer that I am monitoring: template bgp tocore { description "bgp to data center as"; local as 65304; direct; export filter inside_export; import filter inside_import; next hop self; bfd on; }

protocol bgp inside_netA from tocore { neighbor 10.12.0.3 as 65304; source address 10.12.0.11; }

this is the bfd config: protocol bfd { interface "edge*" { interval 300 ms; multiplier 3; }; interface "net*" { interval 300 ms; multiplier 3; }; }

Other than not defining any neighbors directly, it looks just like the docs as far as I can tell.

BGP is working, the peering is established and the routes are passing correctly.

here is the show protocols all from birdc: bfd1 BFD master up 13:16:07 Preference: 0 Input filter: ACCEPT Output filter: REJECT Routes: 0 imported, 0 exported, 0 preferred Route change stats: received rejected filtered ignored accepted Import updates: 0 0 0 0 0 Import withdraws: 0 0 --- 0 0 Export updates: 0 0 0 --- 0 Export withdraws: 0 --- --- --- 0

This machine is .11 and the juniper is .3 on the 10.12.0 net. Here is the tcpdump output: 13:37:23.444104 IP 10.12.0.11.38316 > 10.12.0.3.bfd-control: BFDv1, Control, State Down, Flags: [none], length: 24 13:37:24.251246 IP 10.12.0.11.38316 > 10.12.0.3.bfd-control: BFDv1, Control, State Down, Flags: [none], length: 24 13:37:24.408134 IP 10.12.0.3.49152 > 10.12.0.11.bfd-control: BFDv1, Control, State Init, Flags: [Control Plane Independent], length: 24 13:37:25.056399 IP 10.12.0.11.38316 > 10.12.0.3.bfd-control: BFDv1, Control, State Down, Flags: [none], length: 24 13:37:25.571488 IP 10.12.0.11.bgp > 10.12.0.3.63762: Flags [P.], seq 54144952:54144971, ack 992801306, win 237, options [nop,nop,TS val 995413 ecr 83872572], length 19: BGP, length: 19 13:37:25.673017 IP 10.12.0.3.63762 > 10.12.0.11.bgp: Flags [.], ack 19, win 16384, options [nop,nop,TS val 83880802 ecr 995413], length 0 13:37:25.847516 IP 10.12.0.11.38316 > 10.12.0.3.bfd-control: BFDv1, Control, State Down, Flags: [none], length: 24 ^C13:37:26.408150 IP 10.12.0.3.49152 > 10.12.0.11.bfd-control: BFDv1, Control, State Init, Flags: [Control Plane Independent], length: 24 13:37:26.737727 IP 10.12.0.11.38316 > 10.12.0.3.bfd-control: BFDv1, Control, State Down, Flags: [none], length: 24

and so on

So clearly from tcpdump bird is always saying down and so nothing is setting up. What do I need to do. This is running 1.6.0 right now.
