Juniper QFX5100 around 10
Mikrotik CCR2216 1
Mikrotik CCR2004 the rest
What happen when we try to do the MPLS connection we got duplicate routes, for example
From this router where i took the picture i can ping and tracert to anywhere
This router has the next config
OSPF

From this router we can do everything VPLS tunnels and other things working as is.
But for the next router in the sfp-sfpplus11 from this router
i could ping the 10.253.253.43 directly because 10.253.253.64 this router is directly connected to
but the 10.253.253.66 is connected to 10.253.253.43 and to 10.253.253.102 when the ring is closed
from this router i cant ping or open a vpls connection
