The problem is that when adding a router to vlan interface with the number 100 is added to the interface 10 when added to the 110 it is added to the 11, if you add to it will add 998 to 99, 4000 if you add it to add 40.

Actually the kernel uses right interfaces. 
Use -W key with netstat(1) and it will not truncate interface 
names in the output.
