Just a quick one for you guys. I have been doing a little bit of reading on subinterfaces. I have mostly read about them on Frame Relay interfaces. I have three networks on one side of a FE interface. Can I assign a:

# config t
int f0/0.1
"IP address"


Would this allow the coputers on all the networks to both send and recieve from the router? I would then need to add the new network numbers to the routing table right?

I am going to go with a secondary interface for the new netwroks. [sig][/sig]
 
Good idea , The secondary ip will work just fine !!! [sig][/sig]
 
Cisco's own best practices and my experience show that subinterfaces are the prefered way on Frame-Relay interfaces. There are cautions,

1: deleting subinterfaces can affect currently used Subinterfaces

2: Any line testing will effect ALL attached subinterfaces so keep the number of PVCs small per port.

3: Any load stats are for the PORT total, not the subinterface. You CAN get stats per PVC.

4: LMI traffic is for the PORT and not for each subinterface

5: you CAN bring PVCs up and down without impacting others on the port

And I'm sure there are others I've forgotten or dont know yet :)
