> # Adding Virtual Router IP Addresses

> One virtual router IP address can be configured for a virtual router. If the configured IP address is the same as the interface IP address, this switch automatically owns the IP address. You can configure either an IPv4 address or an IPv6 address.

> According to the VRRP specification, the master VRRP router drops the packets addressed to the virtual router's IP address because the virtual router is only intended as a next-hop router to forward packets. In MDS switches however, some applications require that packets addressed to virtual router's IP address be accepted and delivered to them. By using the secondary option to the virtual router IPv4 address, the VRRP router will accept these packets when it is the master.

> ## Detailed Steps

> To manage IP addresses for virtual routers from Device Manager, follow these steps:

> 1. Choose IP > VRRP. You see the Operations tab of the VRRP dialog box.
> 2. Click the IP Addresses tab on the VRRP dialog box.
> 3. To create a new VRRP entry, click Create. You see the Create VRRP IP Addresses window.
> 4. Complete the fields in this window to create a new VRRP IP address, and click OK or Apply.
