Hoi, Please take a look at the following - it describes how to add Bird into a dedicated *network namespace* (typically 'dataplane') precisely so that the default kernel table is not impacted. From there, the LinuxCP plugin listens to that 'dataplane' namespace instead and installs all routes. https://ipng.ch/s/articles/2021/09/02/vpp-5.html
To take an Ubuntu server and walk through the entire install, so that it is built/configured as a full router, take a look at this article: https://ipng.ch/s/articles/2021/09/21/vpp-7.html The thing you're missing, and may not be obvious from the articles, is that you will run bird (and other things, like sshd or snmpd, etc) in this new namespace, like so (note the bold part in ExecStart): pim@nlams0:~$ cat << EOF | sudo tee /usr/lib/systemd/system/bird-dataplane.service [Unit] Description=BIRD Internet Routing Daemon After=network.target netns-dataplane.service [Service] EnvironmentFile=/etc/bird/envvars ExecStartPre=/usr/lib/bird/prepare-environment ExecStartPre=/usr/sbin/bird -p ExecReload=/usr/sbin/birdc configure ExecStart=*/sbin/ip netns exec dataplane */usr/sbin/bird -f -u $BIRD_RUN_USER -g $BIRD_RUN_GROUP $BIRD_ARGS Restart=on-abort [Install] WantedBy=multi-user.target EOF After that, you can stop, disable and mask the 'bird' systemd unit, and enable the 'bird-dataplane' unit, after creating the network namespace ( https://ipng.ch/s/articles/2021/09/21/vpp-7.html describes this in detail). groet, Pim On Wed, Jun 8, 2022 at 11:11 AM 李海艳 <haiyan...@ilinkall.cn> wrote: > Thanks very much, now my vpp and bird could work together. > > we hope some routes that BGP received not be added to kernel route > table, so that the default kernel table won't be impacted, meanwhile we > hope these routes to be added to vpp. > > we have tried several methods, none could acheive this goal, do you have > any suggestions? > > > ------------------------------ > haiyan...@ilinkall.cn > > > *From:* Pim van Pelt <p...@ipng.nl> > *Date:* 2022-04-24 16:56 > *To:* haiyan...@ilinkall.cn > *CC:* vpp-dev <vpp-dev@lists.fd.io> > *Subject:* Re: [vpp-dev] how BIRD routes integrate into vpp > Hoi, > > 20.01 is somewhat old.
