i (Company Z) learning BGP routes from my Client A from two places on my two seperate Data Center Routers. i need to redistribute those routes into my internal MPLS.
currently i am doing manually statically redistributing all BGP routes from Primary BGP routes into my MPLS cloud and in case Primary BGP with Client A fails i manually remove all routes and start redistributing same routes from my Backup data center into my MPLS cloud.
What are my options to make it auto failover . any suggestions?
Attached is diagram for illustration, any sort of hints would be welcomed.
how the routers in each DC connected to the MPLS cloud learn company A routes ? is it via ibgp or you have static route pointing to the edge router that use ebgp with company A in each DC ?
if the later is the case then you can keep redistribute the static routes but by using ios object tracking where you can track peer availability or a route in the routing table
for example you can advertise a dummy route from the primary data center over the MPLS cloud to be received by the backup DC router over the MPLS link
in the back DC router you can watch this route, once these route disappeared from the routing table a track can be brought to up state that is associated with static route of company A and then they will be redistributed into BGP over the MPLS
I just triggered an idea from online search, what if i create a BGP session in Z Primary Data Center between company Z MPLS Router and edge router connecting to company A. and then all routes will go to my MPLS cloud itself since BGP already running in MPLS cloud of company Z, and simillar i can do from company Z backup data center with higher AS_Path.
is it an option?
is it possible to create EBGP across ASA?
will my friewall rules/NAT keep working as before?
Hi I have this primary configuration on the primary CSR Router in the HA
mode in same AZ but I am not seeing failover to secondary CSR I am
seeing on the backup router that the API call was successful. 10 10 Actv
