The OSPF TE topotest is using switches to interconnect router. During the test,
interfaces are shutdown on some routers to simulate link failure and check that
the TED is correctly updated. However, the switche between router avoid the
detection by the neighbor router that the interface is down i.e. the interface
line remains up as it is conneted to the switch and not to the router.

This patch update the tested topology by removing the switch and connect
directly the router excepted the inter AS link on R3. Interface are also
renamed accordingly.

Let's say we this:

```
$ ip link set down dev r1-eth0
$ ip link set up dev r1-eth0
```

But at the same time we have this interface configured by the FRR too:

```
interface r1-eth0
 ipv6 address fe80:1::1/64
exit
```

We never re-add fe80:1::1/64, when the interface comes up, and we have a
strange situation where NHT stops working and other stuff depending on NHT
stops too (BGP peering, etc.).

the path is marked as not VALID but the routes
were not unimported from tenant vrfs, which lead to
