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> Regards, John -----Original Message----- From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of Carl Baldwin Sent: Tuesday, November 26, 2019 7:29 PM To: vpp-dev@lists.fd.io 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.
