[j-nsp] RPD event M20

[Juniper]

Hello,

I've just executed this comand on the shell and it appeared a lot of routes:

[..]

The output is very long ( I had to stopped after 3 minutes) and we don't 
know if that is normal o no. What should we do? Is it possible to clean 
this routes?

Thanks a lot for your help,

Matthew
