L3 plugin

The l3plugin is a Core Agent Plugin that is designed to configure ARP entries and routes in the VPP. Configuration managed by this plugin is modelled by the proto file.

ARP entries

The configuration must be stored in etcd using the following key:

/vnf-agent/<agent-label>/vpp/config/v1/arp/<interface>/<ip-address>

An example of configuration in json format can be found here.

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 arp.json file

vpp-agent-ctl -put "/vnf-agent/vpp1/vpp/config/v1/arp/tap1/192.168.10.21" json/arp.json

The vpp-agent-ctl also contains a simple predefined ARP entry config. It can be used for testing purposes. To setup the predefined ARP config run:

vpp-agent-ctl -arp

To remove it run:

vpp-agent-ctl -arpd

Proxy ARP

Proxy ARP configuration is composed from two parts; interfaces that are enabled and IP address ranges. Both of these configuration types are stored under separate keys.

For proxy arp interface array, use key:

/vnf-agent/<agent-label>/vpp/config/v1/proxyarp/interface/<if-cfg-label>

For proxy arp ranges:

/vnf-agent/<agent-label>/vpp/config/v1/proxyarp/range/<rng-cfg-label>

An example configuration for interfaces can be found here. An example configuration for IP ranges can be found here.

Predefined configuration in vpp-agent-ctl for interfaces:

vpp-agent-ctl -prxi

For ranges:

vpp-agent-ctl -prxd

Routes

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 -route

To remove it run:

vpp-agent-ctl -routed
