HI everybody
Shoot me if yo must, apparently i made a mistake when addressing the E
interfaces 1 has 24 bit subnet mask while the other has 26 bits notice this
while changing my network commands in router ospf 100 the fact that R4 did
not create an adjacency should have hint me but... (thanks to dennis, but
anyway i can use an inverse 24 bit mask, it doesnt matter that the mask of
the interface is just 26 as long as the interface is listed when you do a sh
ip ospf inter, just a tip)
Anyway guys thanks for your help
