My network consists of 15 towers and one edge router that connects to the internet. Each tower has redundant links to the edge router. In my diagram, I used three towers to simplify my explanation.
By designing the network as follows, I may be able to use only bgp:
- A vlan should be tagged on all switches that Tower3 uses to connect to the Main router.
Tower3 will see Main router as next hop, so if Route1 is unreachable, it will automatically switch to alternate route. This eliminates the need to use Recursive Routing, Netwatch, or other internet monitoring methods for the gateway.
- A vlan will be tagged from Tower3 to Tower2 and from Tower3 to Tower1, in order to access any services that are hosted on the respective towers. For example, if Tower1 hosts a FTP server, Tower3 doesn't have to go all the way to the main router and back to Tower1.
Here is a simplified diagram:
Anybody else implemented something like this? If so, how's it going?
