  • 1.  Secondary IP address for a Vlan

    Posted 02-22-2012 01:55

     

    We have a EX4200 series as a distribution layer switch in our network and we have multiple Vlan's configured on the switch.

    We want to slowly migrate this vlan's to a new subnet. Not a complete migration but a phase by phase migrated.

     

    We would like to keep both the subnet in same vlan until all servers IP address are changed.

     Please advise on how to configure the secondary subnet in a single Vlan as supported in Cisco switches.

     

    int vlan100

    ip address 10.x.x.x 255.x.x.x

    ip addresss 192.x.x.x 255.255.x.x secondary

     

    Thanks

    Manju

    Hey,

     

    Exactly the same way you would do it on any other Junos device - just add additional IP. Nothing will be overwritten so no worries:

    set interface vlan unit 100 family inet addres 10.x.x.x/yy

    set interface vlan unit 100 family inet addres 192.x.x.x/yy

     

    Thanks,
