FW: Advertise loopback IP into BGP - BIRD 2.0.1

Can someone help me on this please ?

My goal is to just export lo:10 interface IP (10.10.200.3/32) through eBGP and import all the routes on the BGP. With the following configuration, I am able to import all the routes, but export of lo:10 interface route is not happening. Below is my bird.conf , what is that I am missing? router id 198.51.100.10; filter http_loopback { if net = 10.10.200.3/32 then accept; } #protocol kernel { # ipv4 { # import all; # export all; # Default is export none # }; # scan time 20; # persist; # Don't remove routes on BIRD shutdown #} protocol direct { interface "lo:10"; ipv4 { export filter http_loopback; }; } protocol device { scan time 10; # Scan interfaces every 10 seconds } protocol bgp { local 10.10.100.2 as 65110; neighbor 10.10.100.1 as 65001; ipv4 { export filter http_loopback; import all; }; } I have a doubt, the "show route" output is also not showing the lo:10 ip in the table. Why is it not in the table. And "show protocol all" output under BGP shows below, it has 6 routes received and 6 rejected for Export updates. Why is it rejecting. Channel ipv4 State: UP Table: master4 Preference: 100 Input filter: ACCEPT Output filter: http_loopback Routes: 6 imported, 0 exported Route change stats: received rejected filtered ignored accepted Import updates: 6 0 0 0 6 Import withdraws: 0 0 --- 0 0 Export updates: 6 6 0 --- 0 Regards, Thiruvazhiyan Lakshmanan NVP – Testing and Certification team Room - A3 1C-24 Middletown, NJ 07748 USA Email: tl488q(a)att.com<mailto:tl488q@att.com> Office: +1 732 420 8076 Mobile: +1 732 331 3485 -----Original Message----- From: Robert Blayzor [mailto:rblayzor@inoc.net] Sent: February 26, 2018 6:01 PM To: LAKSHMANAN, THIRUVAZHIYA Subject: Re: Advertise loopback IP into BGP - BIRD 2.0.1 Is your goal to ONLY export the loopback? If so, disable the kernel protocol and either just do direct or even statics… I never use kernel as I’m not using my servers as a router, but rather as just a route server, so I never change or export the actual servers routing table. You have to add an export to your direct… try: protocol direct { interface "lo:10”; ipv4 { export filter http_loopback; }; } protocol bgp { ... ipv4 { import all; }; } — Robert Blayzor E-Mail/XMPP: rblayzor.AT.inoc.net PGP: https://urldefense.proofpoint.com/v2/url?u=https-3A__inoc.net_-7Erblayzor_&… > On Feb 26, 2018, at 5:46 PM, LAKSHMANAN, THIRUVAZHIYA <tl488q(a)att.com<mailto:tl488q@att.com>> wrote: > > protocol direct { > interface "lo:10"; > } > filter http_loopback { > if net = 10.10.200.3/32 then accept; > } > protocol kernel { > ipv4 { > import all; > export all; # Default is export none > }; > scan time 20; > persist; # Don't remove routes on BIRD shutdown > } > protocol device { > scan time 10; # Scan interfaces every 10 seconds > } > protocol bgp { > local 10.10.100.2 as 65110; > neighbor 10.10.100.1 as 65001; > ipv4 { > export filter http_loopback; > import all; > }; > > }

several issues migrating to bird 2.0.1
by Bjoern Franke 26 Feb '18

26 Feb '18

Hi, I'm trying to transition a config from 1.6.3 to 2.0.1. 1. What's the pendant to protocol kernel { kernel table 42; scan time 45; [...] } "kernel table" produces a syntax error. 2. without "kernel table", I get bird started, but it rejects configured BGP connections: HE: Incoming connection from 2001:7f8:33::a100:6939:1 (port 8002) rejected Config for HE: protocol bgp 'HE' { neighbor 2001:7f8:33::a100:6939:1 as 6939; local 2001:7f8:33::a120:5298:1 as 205298; ipv6 { import all; export filter my_net; }; } I compared this part with the example config and have no clue why the sessions get rejected. Kind regards Bjoern

routes import in BIRD
by ABBAS, KASHIF 26 Feb '18

I have a question.... Bird is importing routes directly from kernel... OR Felix is importing routes to BIRD..?? Is there any using CL I can check this behavior...?? Thanks, Kashif Abbas
