-""" TestLB is a subclass of VPPTestCase classes.
-
- TestLB class defines Load Balancer test cases for:
- - IP4 to GRE4 encap on per-port vip case
- - IP4 to GRE6 encap on per-port vip case
- - IP6 to GRE4 encap on per-port vip case
- - IP6 to GRE6 encap on per-port vip case
- - IP4 to L3DSR encap on vip case
- - IP4 to L3DSR encap on per-port vip case
- - IP4 to NAT4 encap on per-port vip case
- - IP6 to NAT6 encap on per-port vip case
-
- As stated in comments below, GRE has issues with IPv6.
- All test cases involving IPv6 are executed, but
- received packets are not parsed and checked.
