Routing redistribution is a big topic and I have numerous questions
myself. I have jotted down some notes but can't say that I understand it
all yet.
For example on RIP<>OSPF I see this suggested :
- *RIP --> OSPF:* Use administrative distance on the RIP side for the
RIP networks to lower the distance to less than OSPF
- *RIP <-- OSPF:* OK: OSPF = 110 , RIP = 120
I have seen examples where this is used even if there is only ONE router
doing the mutual redistribution. Why is it necessary in such an example?
