Openflow Mode for ASR9000
Openflow for the Cisco ASR 9000 Series router functions in the Integrated Hybrid mode. In this mode, both
Openflow and normal switching and routing (for layer 3) operations such as L2 ethernet switching, L3 routing,
etc are supported. Packets processed as the Openflow forwarding path can be processed as a normal forwarding
path.
OpenFlow Table Types
An OpenFlow flow table consists of a set of flows. Each flow contains a set of matches and actions. A table
has a set of capabilities in terms of supported matches and actions. Just like a policy-map, a table can be
applied to a set of targets but only in the ingress direction. Hence, OpenFlow matches and actions are applied
to the incoming traffic only.
A set of ordered tables is referred to as a pipeline. A pipeline may contain one or more ordered tables. An
OpenFlow pipeline of an OpenFlow switch on ASR9K supports only one flow table.
