HI Julio,
even if R1, R2 and R3 can ping eachother with this configuration, I notice
the following problem when configuring OSPF:
- the adjacencies are up
- but R3 can not istall any OSPF route out of the LSA received from R1
complaining that the advertising route is unreachable
I guess this stems from the fact that R3 has 2 interfaces in the same subnet
and as soon as I delete one of them, then everything works as it should
I this topology I would rather use 2 different subnets.
Bit.
