%description:
Testing dynamic behavior of RIP routing

Topology with 2 hosts and 4 routers:

             RA
           /    \
   H1---R1        R2---H2
           \    /
             RB

Each link has metric 1, except between R1 and RB which has metric 2.
RA is shut down 200s and restarted at 400s.

It is checked that:
 - initially the route from R1 to H2 goes through RA and has metric 3.
 - at 220s R1 has a route to H2 through RB and has metric 4.
 - at 430s R1 has a route to H2 through RA again and has metric 3.
