Currently i have ISP setup which is running in active/pasive mode means.
I have four router
1).Two Router in Core -OSPF & IBGP
2).Two router in Distribution--OSPF & IBGP
Core RoutCore Router-1 is having LP-300 so incoming will be prefereed from Core Router-1 & for outgoing we had set injected defualt toute with riginate metric 2 metric-type 1 so outgoing will from Core route-1 only.
Core RoutCore Router-2 is having LP-200 so incoming will be prefereed if Core Router-1 is down.& for outgoing we had set injected defualt toute with riginate metric 10 metric-type 1.
Setup is running succesfully & we had been told to setup parrelll setup wich will have differnet set of customer & in case any problem they need to be automatically taken care to announce on from Setup-1.
I was thinking to setup same as Setup but if i run OSPF on both the setup then prefered outgoing will from Setup-1 due to defualt route.
Kindly suggest best possible way of setting up IBGP with upsteam & downsteam(Setup-1 & setup-2)
I am attaching the setup-1 configuration with setup --1 & Setup--2 Diagram.
