These two radio buttons enable the “always-on” functionality and additionally the facility
to return to the in-service state after a disconnect event.
Put this interface “Out of Service” when an always-on connection attempt fails
Normally, always-on interfaces will not go out of service unless they have connected at
least once. When checked, this checkbox causes the router to put the interface out of
service even if the first connection attempt fails.
Attempt to re-connect after s seconds
The parameter in this textbox specifies the length of time in seconds that the router
should wait after an “always-on” PPP connection has been terminated before trying to re-
establish the link.
If a PPP interface that would be inhibited by this PPP is connected, attempt
reconnection after s seconds
The value in this textbox takes precedence over the previous parameter when another
PPP instance that is usually inhibited by this one is connected. This parameter would
typically be used to reduce the connection retry rate when a lower priority PPP instance is
connected.
Wait s seconds after power-up before activating this interface
The value in this textbox is the initial delay that the router will apply before activating the
PPP instance after power-up. After the initial power-up delay the normal always-on
activation timers apply. If set to zero, no delay will be applied.
Keep this interface up for at least s seconds
The value in this textbox specifies the minimum period that the PPP interface should remain
available. This means that even if the link becomes inactive before this period expires, the
connection will remain open.
Enable Multilink PPP on this interface
When checked, this checkbox enables the multilink PPP capability of the router. (See above
for configuration details).
Click here to assign a timeband to this interface
Clicking this link redirects the browser to the timeband configuration page Configuration –
Network > Timebands.
Add a route to a.b.c.d if the peer’s IP address is not negotiated
Normally, the IP address for a device connecting to a remote peer is assigned by the remote
peer. If this is not the case then the router will need a route to the remote peer. The value
in this textbox is set to the IP address of the remote peer so that it can be added to the
routing table.
Forward IP broadcasts over this interface if the interface is on the same IP
network as an Ethernet interface
When checked, this checkbox causes the router to route broadcast packets to and from
Ethernet interfaces. This will only occur if the PPP instance has issued an address which is
part of the Ethernet interface network.
Send LCP echo request packet to the remote peer
When checked, this checkbox reveal the configuration parameters that cause the router to
send Link Control Protocol (LCP) packets to the remote peer at specified intervals. This
facility can be useful for keeping a link active (W-WAN, for example).
Send LCP echo requests every s seconds
The value in this text box sets the interval at which to send the packets. When set to
zero, the transmission of LCP packets is disabled.
