P2P Between Switch & Firewall

[Mokhalil82]

Hi

May be a simple question, just wanted to know if I am on the right lines. I need to configure a p2p link with a /30 mask between a cisco 3750 switch and a asa 5510. Then another p2p link between 2 firewalls with a /30 mask. How best is this done.

Thanks

On the switch side, you could either have your firewall on a vlan or a routed port. You would address them appropriately and do the same thing on the p2p link between the other firewalls.

On the switch, you would do something like:

int vlan 10

ip address 10.10.10.1 255.255.255.252

OR

int g0/1

no switchport

ip address 10.10.10.1 255.255.255.252

The lan interface on the ASA would be configured for 10.10.10.2/30.

HTH,

John
