i know that question is asked for many times ,, i have attched my network design with OSPF Areas , R0 is connected to R1 & R2 with Point to point links and tunnels through internet. my question is
which design is fit to my requirements i need :
1- to put floating static route between R1 and R2 for backup reasons.
2- not to flood the area with many LSAs
so in case of multiple areas how can i overcome the problem of connecting R1 and R2 by floating Static route and connecting Area 1 to area 0 in case of failure without redistributing that route in OSPF..?
Yes you would need to change cost dramatically to make route throughout R0, as the direct connection is better by default. So good that you may want to use it all the time.
