Default Route Setup with Multiple /26 VLANS

Hi Everyone,   A new "business requirement" made us create over 53 VLANs now which are all /26. Each one has its own default gateway on the Layer 3 switch. I currently had a default route added to...

Hi Jeff,

 

You can simply add the additional routes per VLAN in the LTM config. Is it not allowing you to do so for the 53 /26's? Is there an error it is giving you?

 

There aren't really any limitations on the LTM in regards to standard IPv4 routing. Regardless of the number of routes or vlans there should be no issue with inter-subnet communication Hope this helps

    Thanks, no it is not letting me. I think the reason is that currently, we only have the 0.0.0.0 default route which points up to the L3 Gateway. If I were to add the gateway's in for the rest of the /26's.....I'd have to add the "destination", "netmask" and "gateway".....what would the "destination" be?? I would think it should just be a gateway IP address twice?? I would think a default route should have covered everything though?
