The l3plugin is a Core Agent Plugin that is designed to configure routes in the VPP. Configuration managed by this plugin is modelled by the proto file. The configuration must be stored in etcd using the following key:
/vnf-agent/<agent-label>/vpp/config/v1/vrf/0/fib/
An example of configuration in json format can be found here.
Note: Value 0 in vrfID field denotes default VRF in vpp. Since it is default value it is omitted in the config above.
If you want to configure a route for a VRF other than default, make sure that the VRF has already been created.
To insert config into etcd in json format vpp-agent-ctl can be used.
We assume that we want to configure vpp with label vpp1 and config is stored in the routes.json file
vpp-agent-ctl -put "/vnf-agent/vpp1/vpp/config/v1/vrf/0/fib" json/routes.json
The vpp-agent-ctl contains a simple predefined route config also. It can be used for testing purposes. To setup the predefined route config run:
vpp-agent-ctl -cr
To remove it run:
vpp-agent-ctl -dr
