Hi

hi ali...

here you have to deal with the STP calculation... or you can use multiple spaning tree for different vlan... noramlly in our STP we have one root bridege for all the vlan... now you have to configure your priority such that for one VLAN one sw will become root bridge and for other VLAN other sw will become root bridge...

it will be good if you give detail with diagram...

along with STP to assist in providing the correct path you wish to take, you'll also need to consider layer3 load balancing with HSRP for your 'load balance & redundancy between the two vlans'.

spanning-tree vlan 11 PRIRITY 8192

spanning-tree vlan 10 PRIRITY 13384

Can any EXpert confirm;am not sure

IN Regardes to the redundancy of the vtp

maybe the command is mls rp vtp test.also am not sure

hi ali...

your configuration looks perfect as per your requirement... as here you assign the different priority value to the different vlan so ds1 will become root bridge for vlan 10 and ds2 will be root bridge for vlan 11
