[NETVIRT-1307] L3VPN: IPv6 Datapath not working with DC-GW

Fri, 29 Jun 2018 08:51:06 +0000

IPv6 Datapath not working with DC-GW

Create N1 with S1(IPv4) and S2(IPv6).
Create Port and boot VM
Validate DC-GW and Local routes learned in both ODL and DC-GW
Verify datapath for Both IPv4 and IPv6.

Observations:

1. Packet in flows hitting IPv4 path instead of IPv flow path.

2. Incorrect Source MAC address observed.
