I am trying to configure erspan between two nexus 7K my question here is regarding the origin IP address on a nexus7K with multiple VDCs.
The example below is from cisco website
With a Nexus 7K with multi VDC (from example below) should we have loopback1 configured in the admin VDC or the VDC we are trying to mirror traffic from. (As the monitor origin ip address x.x.x.x global command can only be configured in the admin VDC)
switch_1(config)#monitor erspan origin ip-address 10.254.254.21 global
!--- Configure the IP address for loopback interface, which is used
!--- as source of the ERSPAN traffic.
switch_1(config-if)#ip address 10.254.254.21/32
