URGENT! VPN with multiple peers in same subnet

Hi,

I desperately need replies and answers to my query below.

I connect a routerA 10.10.1.1/24 to a switch.

This switch is then connected to 3 other routers - 10.10.1.2/24, 10.10.1.3/24 and 10.10.1.4/24 - in a star topology.

RouterA is the Hub, and the 3 other routers are spokes.

How do I configure a VPN tunnel using same ISAKMP key from routerA for all 3 routers?

After I entered "crypto isakmp key cisco address 10.10.1.2 255.255.255.0" for routerB.

When I tried to enter the same key for 10.10.1.3, I got an error message to say the key for the subnet has already been set.

Pls help!

Rgds,

Rachel

Hi

Have you tried configuring host specific keys to the remote peers ?

crypto isakmp key cisco address 10.10.1.2 255.255.255.255

crypto isakmp key cisco address 10.10.1.3 255.255.255.255

crypto isakmp key cisco address 10.10.1.4 255.255.255.255
