Framing is done at the Data Link layer (Layer 2).
Routing is done at the Network layer (Layer 3).
All layers - but to the greatest extent, the distinctive work done by the router - specifically, routing packets - corresponds to layer 3.
The routing process occurs in the 3rd OSI layer (network layer) routing protocols use network address (IP address in TCP/IP) to chose the correct path to the destination. ps: You can also have routing protocols on other layers sometimes (application layer in p2p routing) but this is something completely different.
I assume you're talking about portion of the OSI model that handles character-encoding such as ASCII. It is the Presentation Layer of the OSI model.
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
Data link layer
network layer
Networking layer of the OSI model
The INTERNET LAYER of OSI model exists for "routing" and providing a single network interface to the upper layers.
(True) SONET Specifies framing and multicomplexing at the physical layer of the OSI model.
Layer 3 - network layer.

network layer
The three layers of the OSI standard are application layer, transportation and Network layer. Network layer provides the electrical and mechanical interface to network medium, network layer handles routing and forwarding of data. The transport layer ensures data is successfully sent and received between two nodes..
