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.
Assuming the multi-vrf test case succeeded, this one adds BGP routing with
CE routers.

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

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