I am looking for some assistance and or verification with eBGP. Any assistance is greatly appreciated.
Example BGP topology on a private network:
Router A is the primary site. AS 1.
Router B is the hot stand by site. AS 2.
Router C is at a remote site. AS 3.
Router A & B advertises the same networks to router C via BGP.
Router C advertises various networks back to routers A & B.
Router A & B redistributes BGP into OSPF.
I need to control path selection.
Circuit between router A & B is the primary path and must be used. Circuit between B & C is the secondary circuit for failover.
Since this is purely eBGP, I believe local pref is not an option. I am also not able to use weights as router C at the remote end is not Cisco.
Any Suggestions? Your assistance is most appreciated.
