.. cfgcmd:: set interfaces pppoe <interface> mru <mru>
Set the :abbr:`MRU (Maximum Receive Unit)` to `mru`. PPPd will ask the peer to
send packets of no more than `mru` bytes. The value of `mru` must be between 128
and 16384.
A value of 296 works well on very slow links (40 bytes for TCP/IP header + 256
bytes of data).
The default is 1492.
.. note:: When using the IPv6 protocol, MRU must be at least 1280 bytes.
