Hey guys, I have been searching the topic but i am not sure im finding anything that fits the scenario i am trying to achieve. where both Routers are active and share an IP address like VRRP accomplishes.
Current Setup
So my current setup is I have 1 Cisco 2900 Router connected to 2 ISP’s. One of the connection is a 100/100, and my other is 50/50.
BGP is established I have a /24 block that I advertise. On my end I have this subnetted into a 1 /25 and 2x /26’s This works other than the Router is EoL and I want to add redundancy in case one connection goes down as well as if on my end a piece of hard dies.
So I purchased to new Cisco Routers and I want to hook each one for a 1 to 1 link.
I do not necessary want to do load balancing where I say hey… first half of my /24 subnet goes out ISP #1 and the other out ISP #2.
I want it to where there is redundancy in case a link or one of the router goes offline. So I was thinking HSRP but that I believe would make one of the routers inactive rendering one of the ISP’s I have not usable.
In my mind both routers would have something that HSRP achieves in which they have an identical virtual IP address to serve as my /24 gateway (so 3 shared ip address actually since i have my /24 subnetted). I would like it to work that if it came in on ISP #1 then it goes out on ISP1, unless that link went down and vice versa for ISP2.
Looking for some input on the matter.
New Planned Setup ( this one has a little more detail on what the routers connect to)
Thanks for taking a look.
