  • Hi Miak,

     

     

    I don't think you can logically tie the two VLANs together so that a failover only occurs when both VLANs are down. Can you provide more detail on the scenario? Maybe there is another solution.

     

     

    Thanks,

    Hi Aaron

     

     

    Thans for your reply,

     

     

    This senario is for 2 site. site1 has 2 lc's and site2 has 2 lc's. and we have 4 links,

     

     

    Site1

     

    LC-1 is connected to cisco switch1

     

    LC-2 is connected to cisco switch2

     

    Trunk bw the switchs

     

    LC-1 and LC-2 is also connected to internal network

     

     

    Site2

     

    LC-1 is connected to cisco switch1 at site1 directly

     

    LC-2 is connected to cisco switch2 at site1 directly

     

    Trunk bw the switchs

     

    LC-1 and LC-2 is also connected to internal network

     

     

    Links (note: links are direct no public ip's)

     

     

    links are in 2 vlans X and Y.

     

    link1 is in vlan x

     

    link2 is in vlan y

     

     

    link3 is in vlan x

     

    link4 is in vlan y

     

     

    if link1 and link2 go's down ( which is connected to LC-1 at site2 to switch at site1)failover should occure. where we can use link2 and link3 connected to lc2.
