Dear All,
I have VLANs configured on a Cisco core switch. Where the default gateway of this Coreswitch is Firewall 1. Lately, Firewall 2 was installed where I need one of the VLANs traffic to go outside Firewall 2.
Will the following configuration work?
interface Vlan10
ip address 172.16.10.1 255.255.255.0
interface Vlan20
ip address 172.16.20.1 255.255.255.0
interface Vlan30
ip address 172.16.30.1 255.255.255.0
interface Vlan100
ip address 172.16.100.1 255.255.255.0
ip route 172.16.10.0 255.255.255.0 172.16.10.14 (Goes through Firewall 1)
ip route 172.16.20.0 255.255.255.0 172.16.10.14 (Goes through Firewall 1)
ip route 172.16.30.0 255.255.255.0 172.16.10.14 (Goes through Firewall 1)
ip route 172.16.100.0 255.255.255.0 172.16.100.2 (Goes through Firewall 2)
Thanks in advance!

you mention that the FW is default GW for host, so the inter-vlan is done in GW not in SW
if VLAN100 what to talk to other VLAN does FW2 have route to other VLAN and does FW1 have route to VLAN 100?
