About routing in Data ONTAP

About Data ONTAP routing

Although the filer can have multiple network interfaces, it does not function as a router. The Data ONTAP software does not route packets between the interfaces of the filer on behalf of other network hosts; however, Data ONTAP can route its own outbound packets.

Data ONTAP uses two routing mechanisms:

fast path
To route Network File System (NFS) packets over User Datagram Protocol (UDP) and to route all TCP traffic, Data ONTAP uses a mechanism called fast path. See About fast path.
routing table
To route all other IP traffic, Data ONTAP uses the information available in the local routing table. See About the routing table.
