%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.
The link between R1 and RA is broken at 200s and restored 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.
