Hi All,
We are in the process of migrating our servers from old DC to a new DC. with the new DC already have pre-existing vlans and servers.. please take note we are not running any vxlan on new DC just a simple nexus core/access server farm setup.
we only have 2 DWDM so the connection will be pair of nexus 9k connected to another pair of nexus of 9k on both sides that will run the VXLAN bridge.. then from these it will be connected to access layer and just trunk the l2 access vlans. simple.
Our goal is just to move the L2 vlans..
DCA VLANS 300 will be converted to vlan 600 at DCB
vlan 301 to vlan 601
vlan 400 to vlan 800
vlan 401 to vlan 801
VPC is working fine; OSPF IGP is working fine as well with BFD configured for fast link failure detection..
thinking to manually load balance the l2 traffic. spanning tree is configured with A1 as root bridge for vlan 300/301 ( B1 root bridge for 600/601)
A2 root bridge for vlan 400/401 (B2 root bridge for 800/801.)
we are facing an issue when we do the failover test.. the failover doesnt work..
