I would guess that they actually want 1 of the following:

Redundancy of some sort.
Increased bandwidth to the router.

Subject: Router with 2 (or more) interfaces in same network


I am curious to know if its possible to have a router with its two
interfaces, say configured as, and Theoretically, i see nothing which can stop a
router from doing this.
But practically, is it of any use? And if used, then, when and why will
somebody want to use such
a kind of configuration?

Would appreciate if somebody could enlighten me on this.


I have a customer who insists he wants to do this, without providing any
