The device under test has two VRFs with two interfaces in each VRF.
Routers are attached to those interfaces and run BGP with device under test
in a dual-stack (IPv4 + IPv6) environment.

The routing and connectivity tests focus on IPv6 (another test cases focuses
on IPv4), the dual-stack addressing is used only to trigger the incorrect
activation of BGP address families.

* r1 and r2 should be able to ping each other and rtr VRF loopback
* r3 and r4 should be able to ping each other and rtr VRF loopback
* r1 should not be able to reach r3

The test also checks whether DUT unnecessarily enables IPv4 AF over IPv6
EBGP sessions
