Okay ive added this route, I had the 0.0.0.0 route in  as I read the xorp
doc and stated that this is better to use this with tunnels. So now I added
this other mrib-route below the 0.0.0.0 in my config.

So now

show pim mrib :
DestPrefix         NextHopRouter   VifName VifIndex MetricPref Metric
0.0.0.0/0          10.254.0.13     tun0    1                 1      1
10.132.3.0/24      10.132.3.20     eth0    0                 0      0
10.254.0.0/30      10.254.0.13     tun0    1                 1      1
10.254.0.12/30     10.254.0.14     tun0    1                 0      0

and show route table ipv4 multicast final :

0.0.0.0/0       [static(1)/1]
                > to 10.254.0.13 via tun0/tun0
10.132.3.0/24   [connected(0)/0]
                > via eth0/eth0
10.254.0.0/30   [static(1)/1]
                > to 10.254.0.13 via tun0/tun0
10.254.0.12/30  [connected(0)/0]
                > via tun0/tun0

After this well, it's kind of the same thing, the linux box join no
multicast group.
