With the newer VPP, since around 18.04, IP table must be created before an
interface can be set to it. The default global IP table 0 is an exception
because it is already present on startup.
The CLI is:
vpp# ip table ?
ip table ip table [add|del] <table-id>

Subject: [vpp-dev] Trouble adding loopback to ip table
Hi folks. I'm playing around a bit with vpp for the first time. I'm stuck on
something and don't know where to go from here...
I'm trying to add a loopback interface to ip table 5. From the
documentation[1], this table should be created by this command if it does not
exist. However, what happened seems to contradict this.
vpp# set int l2 bridge loop0 13 bvi
loop0
vpp# set int state loop0 up
vpp# set int ip table loop0 5
set interface ip table: no such table 5
I cannot find any command that would explicitly create table 5 for me so that
this can succeed. Maybe I missed something. Any thoughts on this?
For a little context, at the moment, I'm just going through this vxlan page [2]
trying to get a better feel for vpp. I installed vpp on Ubuntu bionic according
to the instructions. apt-cache shows that I have 19.08.1-release from
packagecloud.io/fdio/release.
I do plan to dive a little bit more into the code. In the meantime, I will try
to set up a build environment.
Thank you,
Carl
