2. PPP Configuration
2.1. Base Interface
Configure the PPP parameters related to the base interface going to be used.
Example:
Config>global-profiles ppp
-- PPP Profiles Configuration --
PPP Profiles config
PPP Profiles config>
PPP Profiles config>lcp-options umts2/0 default
PPP Profiles config>lcp-options umts2/0 acfc
PPP Profiles config>lcp-options umts2/0 pfc
PPP Profiles config>lcp-options umts2/0 accm 0
PPP Profiles config>
PPP Profiles config>exit
Config>
2.2. PPP Connection Profile
Here we must indicate that the PPP interface must use the UMTS interface as the base interface
(“
base-interface umts2/0 link” command) and use the UMTS profile for dialing (“base-interface
umts2/0 profile UMTS” command).
Similarly, program the appropriate parameters for the protocol.
The user and password sent during authentication must be appropriate for the carrier and the service
being used to connect (“
authentication sent-user XXXXXX password YYYYY” command). These are
simply examples.
The IP address is normally assigned during the negotiation phase (“
ipcp local address assigned”
command).
Echo functionality is not required (“
lcp echo-req off” command). The PPP is only significant locally,
i.e. between the router and the connected UMTS module. The echo DOES NOT detect link drops nor
loss of signal.
Similarly, the extreme remote IP address that appears during negotiation is the module internal IP
address, which again makes no sense to have in the routing table. This can be ignored by using the
“
no ipcp peer-route” command.
Example:
Config>network ppp1
-- Generic PPP User Configuration --
ppp1 config> base-interface
-- Base Interface Configuration --
ppp1 Base IFC config>
ppp1 Base IFC config>base-interface umts2/0 link
ppp1 Base IFC config>base-interface umts2/0 profile UMTS
ppp1 Base IFC config>
