TI zone in an edge fabric

In the TI zone, when you designate E_Ports between the front and xlate phantom switches, you must use - 1
in place of the "I" in the D,I notation. Both the front and xlate domains must be included in the TI zone.
Using D,I notation, the members of the TI zone in
• 1,8
• 1,1
• 3,- 1 (E_Port for the front phantom domain)
• 4,- 1 (E_Port for the xlate phantom domain)
Note that in this configuration the traffic between the front and xlate domains can go through any path
between these two domains. The - 1 does not identify any specific ISL. To guarantee a specific ISL, you need
to set up a TI zone within the backbone fabric.

TI within a backbone fabric

A TI zone within a backbone fabric is used to route traffic within the backbone fabric through a particular
ISL. For example, in
EX_Ports 1,1 and 2,1 is routed through VE_Ports 1,4 and 2,7.
