Using Site Manager
To disable loopback checking for this line, do the tasks in the following table.
Setting the Maximum Receive Unit (MRU)
The Maximum Receive Unit (MRU) Size parameter specifies the maximum
receive unit size, in bytes, for the line. The default MRU size for leased lines is
1590 bytes. The default MRU size for dial lines is 1500 bytes.
For leased lines, the router negotiates the MRU size automatically, so you do not
have to configure a value manually. However, to ensure that the router can
negotiate the MRU size successfully, you must disable the RFC1661 Compliance
parameter. This parameter is enabled by default to ensure the correct MRU size for
dial lines.
If you change the size of the MRU and the RFC 1661 COmpliance parameter is
enables, Site Manager and the BCC will automatically increase the size of the
MTU.
For instructions on disabling RFC 1661 compliance, see “Disabling RFC 1661
Compliance.”
Using the BCC
The MRU size and RFC 1661 compliance are included in the
dial
object for PPP
dial interfaces. For instructions on setting the
mru
parameter and
mru-compliance
parameter, see Configuring Dial Services.
