I’ve just upgraded the Reading datacentre from Linksys to Juniper SRX connectivity! Bit of a trauma because I got the PPP password wrong at some point and spent a day trying to make it work with an incorrect password. D’oh.
Final working config on the DSL interface is as follows – turns out that the VCI can be specified as 0.38 or just 38 – it doesn’t seem to make a difference:
root> show configuration interfaces at-1/0/0
encapsulation atm-pvc;
atm-options {
vpi 0;
}
dsl-options {
operating-mode auto;
}
unit 0 {
encapsulation atm-ppp-vc-mux;
vci 38;
oam-period 100;
oam-liveness {
up-count 200;
down-count 200;
}
ppp-options {
chap {
default-chap-secret "not telling you"; ## SECRET-DATA
local-name "not telling you this either";
passive;
}
}
family inet {
negotiate-address;
}
}
Now if SixXS will re-activate my account, I will get working on an IPv6 tunnel…
If you want to trace PPP success or failure, you can’t do it on the interface for DSL. You need to do it under ‘protocols ppp’:
root> show configuration protocols ppp
traceoptions {
file ppp.log;
flag chap;
}
monitor-session {
at-1/0/0.0;
}
Here’s what a PPP interface looks like when it is up – until I got the password correct it was showing ‘CReq Sent’ and ‘closed’ for the LCP status:
root> show ppp interface at-1/0/0 extensive
Sessions for interface at-1/0/0

Here’s my log when it finally succeeded:
