source routing

default route on core 6K=
0.0.0.0 0.0.0.0 a.a.a.a (inet connection via vendor a)
where a.a.a.a = firewallA ethernet add

All net devices utilize the default route.

I want a specific vlan 102 (10.50.102.0 /23) to utilize a different route. A route to inet - via vendor b
b.b.b.b - firewallB ethernet add

SO i utilize Source routing?

My guess to implement
ip access-list TEST

permit any 10.50.102.0 255.255.254.255 b.b.b.b 255.255.255.192

Under VLAN 102 interface
service-acl input TEST


In regards to getting the server vlan to route to vendor b

Is the source routing concept correct? Have I left anything out? Is the syntax correct? Would you recommend using this method to get the desired result. Is their a better way?

Thanks

If 'vendor b' network range is not configured on the PowerConnect switch, communication will fail. 

You will need to add another default route for the 10.50.102.n network as to ensure internet connectivity. 

ip route 0.0.0.0 /0 10.50.102.n -- assuming that 'vendor b' has an internal interface on the same network range as VLAN 102

When an "show ip route" command is initiated, you will see (2) default routes, 0.0.0.0 /0 for VLAN 1 and 0.0.0.0 /0 for VLAN 102.

If 'vendor b' ip address is range is not configured on the PowerConnect switch, communication to the internet may fail as all unknown traffic will be forwarded out of the default route, which the ACL statement prevents.
