+## Tests executed
+
+### Check if FRR is running
+
+Test is executed by running 
+
+	vtysh -c "show logging" | grep "Logging configuration for"
+	
+on each FRR router. This should return the logging information for all daemons registered
+to Zebra and the list of running daemons is compared to the daemons started for this test (`zebra` and `ospf6d`)
+
+### Verify for OSPFv3 to converge
+
+OSPFv3 is expected to converge on each view within 60s total time. Convergence is verified by executing (on each node)
+
+	vtysh -c "show ipv6 ospf neigh"
+
+and checking for "Full" neighbor status in the output. An additional 15 seconds after the full converge is waited for routes to populate before the following routing table checks are executed
+
+### Verifying OSPFv3 Routing Tables
+
+Routing table is verified by running 
+
+	vtysh -c "show ipv6 route"
+
+on each node and comparing the result to the stored example config (see `show_ipv6_route.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are masked out before the compare.
+
+### Verifying Linux Kernel Routing Table
+
+Linux Kernel IPv6 Routing table is verified on each FRR node with
+
+	ip -6 route
+
+Tables are compared with reference routing table (see `ip_6_address.ref` in r1 / r2 / r3 / r4 directories). Link-Local addresses are translated after getting collected on each node with interface name to make them consistent
