This can be a little bit of an odd query however bear with me for a second.
For instance there is a router with three discreet Ethernet ports (every port might be its personal community with a unique subnet/supernet).
Now as an example that each one of those interfaces/subnets are utilizing non RFC1918 IPs.
So for instance as an example
-
interface 1 is: 75.168.2.x/24,
-
interface 2 is 189.54.67.x/24
-
interface three is 7.90.85.X/24
If an IP within the Interface 1 subnet sends visitors to an IP within the Interface 2 subnet will the router ship that visitors internally between the discreet? Or will it try and ship that visitors to the true location of that Dst IP?
In brief the router ought to know that 189.54.67.x/24 is getting used for sources internally and the ought to ship it inside reasonably than out, however with it crossing discreet NICs I wasn’t positive.
