MPLS MTU

Maximum transmission unit (MTU) is a well-known parameter in the IP world. It indicates the
maximum size of the IP packet that can still be sent on a data link, without fragmenting the packet.
Data links in MPLS networks also have a specific MTU, but for labeled packets. Take the case of
an IPv4 network implementing MPLS. All IPv4 packets have one or more labels. This does imply
that the labeled packets are slightly bigger than the IP packets, because for every label, four bytes
are added to the packet. So, if n is the number of labels, n * 4 bytes are added to the size of the
packet when the packet is labeled.
This section explains that an MPLS MTU parameter pertains to labeled packets. Furthermore, it
explains what giant and baby giant frames are and how to ensure that Ethernet switches can handle
them. Finally, a new parameter is introduced: MPLS Maximum Receive Unit. This parameter is
used in the LFIB to keep track of how big labeled packets can be and still be forwarded without
needing to fragment them.
