Help with Vlan on a 3550 switch

Hi,

i got this little prob with a 3550 switch.

I made 3 vlans an it vlan 1 10.71.32.2 255.255.252.0 Vlan 20 10.71.48.1 255.255.254.0 and Vlan 30 10.71.60.1 255.255.255.0 now i need another ip address connected to vlan 1 but i still need to keep the one i use atm, so is it possible to add a second ip to the same vlan or not ?

router eigrp 100

network 10.71.32.0 0.0.3.255

network 10.71.48.0 0.0.1.255

network 10.71.60.0 0.0.0.255

Or does anybody got a better suggestion ?

thx alot ,

steven

This is possible.

You can assign a second ip in the same way as it is don on a physical interface: add the keyword secondary after the IP adress and mask:

ip addr 10.22.1.4 255.255.0.0 secondary

In general it is not adviseable to use more than one ip subnet on the same cable or vlan. This should only be used in situations where it is a temporary solution, for example for an IP adressmigration. On a vlan-capable switch you can simply create an extra vlan.

Regards,

Leo
