Hey folks – finally getting around to a project that has been getting held
up.
We have an MX480 deployed currently that is handling PPPOE traffic. The
interface (AE with 4X10G) configuration is pretty straight forward:
paul@xxxxxxxxxxxx# show interfaces ae3
description “xxxxxxxxxxxxxxxxxxxxxxxx";
vlan-tagging;
auto-configure {
vlan-ranges {
dynamic-profile pppoe {
accept pppoe;
ranges {
any;
}
}
}
remove-when-no-subscribers;
}
mtu 9192;
encapsulation flexible-ethernet-services;
aggregated-ether-options {
lacp {
passive;
periodic fast;
}
}
Obviously there is an access section and a dynamic-profile section to
support this configuration. This works today and well.
Now, we want to bring another VLAN into the MX480 for additional PPPOE
subscribers – but the catch is that this is via a wholesale provider handing
off lt2p tunnels (Bell Canada wholesale).
Today, on our Cisco configuration we have:
vpdn-group AGAS-1005
! Default L2TP VPDN group
accept-dialin
protocol l2tp
virtual-template 1
local name nexicom-1
lcp renegotiation always
l2tp tunnel password 7 xxxxxxxxxxxxxxxxxxxxx
bba-group pppoe global
virtual-template 1
interface GigabitEthernet0/3.901
description Bell AGAS Service (xxxxxxxxxxxxxxxxxxx)
encapsulation dot1Q 901
ip address xx.xx.xxx.27 255.255.255.248 secondary
ip address xx.xx.xxx.28 255.255.255.248 secondary
ip address xx.xx.xxx.26 255.255.255.248
And then virtual template(s) and a few static routes to each the far end of
the l2tp tunnels.
Has anyone converted a configuration like the above Cisco configuration into
a Juniper MX style configuration? I did some reading on l2tp for subscriber
management on JunOS and am confused as ever :)
Thanks,
Paul
