## Configure VRRP Priority

See the first figure in VRRP Topology for the toplology used in this example. You can configure a VRRP instance with a priority so that the router with higher priority will become the master for that instance. You can configure the priority from 1 to 254, with 1 being the lowest priority. A priority of 255 is used for the router that owns the associated IP addresses.

1. Type the following commands in switch 1 to configure VRRP instance 1’s priority as 200.
   1. Enter Global Configuration mode.

          SEFOS# configure terminal

   2. Enter Router Configuration mode.

          SEFOS(config)# router vrrp

   3. Enter Interface Configuration mode for VLAN 2.

          SEFOS(config-vrrp)# interface vlan 2

   4. Configure the priority as 200.

          SEFOS(config-vrrp-if)# vrrp 1 priority 200

   5. Exit Interface Configuration mode.

          SEFOS(config-vrrp-if)# end

2. Type the following commands in switch 2 to configure the priority for VRRP instance 1 as 150.
   1. Enter Global Configuration mode.

          SEFOS# configure terminal

   2. Enter Router Configuration mode.

          SEFOS(config)# router vrrp

   3. Enter Interface Configuration mode for VLAN 2.

          SEFOS(config-vrrp)# interface vlan 2

   4. Configure the priority as 150.

          SEFOS(config-vrrp-if)# vrrp 1 priority 150

   5. Exit Interface Configuration mode.

          SEFOS(config-vrrp-if)# end

3. View the priority in switch 1.

       SEFOS# show vrrp interface vlan 2
       P indicates configured to preempt

       Interface vrID Priority  P  State  Master Addr   VRouter Addr
       --------- ----  -------- -  -----  -----------   ------------
       vlan2    1      200      P  Master local         12.0.0.5

4. View the priority in switch 2.

       SEFOS# show  vrrp  interface  vlan 2
       P indicates configured to preempt

       Interface vrID Priority P  State   Master Addr     VRouter Addr
       --------- ---- -------- -  -----   -----------     ------------
       vlan2     1      150    P  Backup   12.0.0.5       12.0.0.5
