vlan based default gateway

[barzus]

Alteon Web OS allows you to assign different default gateways for each VLAN. You can effectively map multiple customers to specific gateways on a single switch.

do cisco load balancers support different default gateway for each vlan?

[cody.rowland]

Unfortunately, no. At least not as far as I can tell. I've desperately been trying to find a way to do this and I'm having no luck at all.

I'm not familiar with the specific product, but wouldn't you be able to define the specific gateway based on the DHCP scope?

Even if you don't really want to use DHCP (low count of static addresses), you COULD still use DHCP, assign "permanant" IPs based on the port MAC address, and for each subnet's scope, define the default gateway for that scope in the properties.

....or am I missing something?

In this case, DHCP doesn't apply because we're talking about load balancing servers using a CSS. All IP addresses need to be statically assigned.

Cisco put me on the list too, this is a feature the CSS's really need!!

one way of doing it today would be to define a serverfarm for each gateway, and have a vserver match_all for every vlan.

For example,

serverfarm gateway_1

no nat client

no nat server

real

x.x.x.x

serverfarm gateway_2

<...>

vserver gateway_vlan1

virtual 0.0.0.0 /0 any

serverfarm gateway_1

vlan

vserver gateway_vlan2

virtual 0.0.0.0 /0 any

serverfarm gateway_2

vlan
