Question

IP Route Statement

Asked by: cogit

Everything works in my environment ( Vlan routin, failover , etc) and now I want to make sure that my core switches default Gtwy has 2  ip route statements one gtwy for my dmz vlans on 172.27.0.0 (172.27.0.254 Netscreen int) and one for my 10.170.0.0 (10.170.0.254 Trust Netscreen) . When I do a tracert from one device (pc) on 172.27.22.1 it goes out to the internet thru the trusted interface on the FW 10.170.0254.

Sample output.

ip route 127.27.0.0 255.255.0.0 172.27.0.254 sends all data FOR 172.27.0.0/16 TO 172.27.0.254

all other traffic that is not a directly connecte nterface (your VLANs) will go out the default gateway.

You can look at this and all your routes by throwing the 'show ip route' command at the router/switch.
