Hi,
Suposing a CISCO 2600 router with 2 interfaces (Serial ans Fast Ethernet)
On the serial interface I put 10 different gateway for subneted networks
On the fast ethernet I put 8 different gatewat foe subneted networks
when an IP package arrives on Fast Ethernet, how the router discover the net
part of this addrss.
What I mean ?
What subnetmask (of 18 possibles) the router uses to do a Logical operation
with the IP address to disciver the net part of the address ?
If it analyse all the masks of all gateways, the processor will blow down ?
If it uses the standart mask (A, B or C class) it will not route for
subneted address non-standat (like 255.255.255.128) !!!
Thank you a lot
Giuliano
