disable ip routing on sup720 ?

[pbogaerts]

Hi,

Is it possible to disable the layer 3 function on the sup720 in a cat6509E, as a step in the implementation of a secondary core we liked to have just only layer2 and not layer3, i was looking for a command "no ip routing" but couldn't find it in de ios

Thanks

In addition on my previous question.

Do i have an issue when I configure HSRP already on the management vlan + a loopback address

Hi Friend,

HSRP is a gateway redundancy protocol. As understand from your original post you will be using this box as layer 2 box correct? HSRP is configured on layer 3 interface on L3 switch or routers whose interface ip address are used as gateway for end hosts.

If you are planning to deploy this box as layer 3 box then you can configure HSRP on your layer 3 interfaces but that is not required on your loopback interfaces as loopback interface ip address are not used as default gateway by your end hosts.

The secondary switch should work for one week as L2 (first step to make it easy to fall back when there is production), but then we plan to put also the secondary new switch in L3 (HSRP and EIGRP like already configured on the primary), when i put already the management vlan in HSRP and I put a loopback address for TACACS, I would think this should work, because the rest of the vlans is routed by the primary switch, or do I mis something.

Thanks,
