Unique MAC addr required for shared interfaces Security Context?

Hi,

I've a question on security context.

For shared interfaces,

Let's say we have a shared interface of the outside interface using subinterfaces, fa0/0.1 and fa0/0.2.

Both fa0/0.1 and fa0/0.2 is connected to the same network 192.1.1.0/24

fa0/0.1 (.1)

fa0/0.2 (.2)

1. Does both subinterfaces require a unique MAC address assigned to them? This has to be done in each context mode, right?

2. Can I have another option, instead of manually assigning the unique MAC addr, I 'll auto generate the MAC addr to each interfaces? How does the mac-address auto in the global config works? Does it auto generate a mac-addr for each context's subinterfaces?

Thanks.

Re: Unique MAC addr required for shared interfaces Security Cont

The subinterfaces will not require unique mac address if the traffic does not flows between them. mac address auto generate will not be a good option for this.you have to manually configure the mac addresses.
