[NETVIRT-386] SD-VPN:L3 service: remote network: after deleting the configuration some of the remotegw are still shown in the arp table

Thu, 19 Oct 2017 21:27:52 +0000

add a tenant with a L3 service:
2CPE - remote network behind UNI2 on each CPE

traffic:
10 untagged packets from c1u1 (local host) to c2u2 remote host
10 tagged packets from c2u2 remote host to c1u2 remote host

performed the following test:
init_karaf
configuration
send traffic
delete configuration

looking at the arp table i see that the 1 arp entry of the 2 remotegw is still shown there - operational/neutronvpn:neutron-vpn-portip-port-data/

when i performed the same test with 4 CPEs than 3 out of the 4 remotegw were still shown

attached logs of the scenario with the 2 CPEs

config:
