Data traffic path

Subash Sharma

Hi,

I got some confusion regarding the data traffic flow on the below design

Firewall 1 ---------------- HA ------------------- Firewall 2

      |                                                       |

      |                                                       |

Switch 1 ------------- vlan x/30 -------------- Switch 2

Switch 1 & Switch 2 has 10 vlan's. 8 of these vlan's are just L2 vlan's and these vlan's are terminated at Firewalls. The link between Switch 1 and Firewall 1 is a trunk link carrying these 8 L2 vlans. Same goes for the link between Switch 2 and Firewall 2. Firewalls are running at active-standby mode. I also have 2 L3 (SVI) vlan's on these switches. One is used for switch interconnect and other to the distribution layer switches. OSPF is configured as the routing protocol.

My doubt is this. Lets say Firewall 1 is active and firewall 2 is just standby. I need to know the traffic path that my data traffic will take from the Server's connected to Switch 2 to Firewall 1. Will it take

Switch 2 --------------> Firewall 2 --------------> Firewall 1

                                   OR

Switch 2 -------------> Switch 1 ----------------> Firewall 1

please advice...

thanks & regards

Hi,

You can do it by yourself by simply checking routing table on switch 2. As those switches are running OSPF as understood.

sh ip route

Hope it will help.
