Also make sure you talk to your Juniper SE and engage him in your plans - make sure you understand which code releases you require for your deployment. The last I checked, LNS was not supported on MX80 but that may have changed in recent 13.2 code.
Like everything there’s several ways to configure things - here’s a pretty base configuration that will hopefully help point you in the right direction… the local pool assignment isn’t need if your Radius is going to hand out all dynamic addresses... dynamic-profiles { PPPOE { predefined-variable-defaults { input-filter PERMIT-ALL; output-filter PERMIT-ALL; } interfaces { pp0 { unit "$junos-interface-unit" { ppp-options { pap; } pppoe-options { underlying-interface "$junos-underlying-interface"; server; } keepalives interval 30; family inet { filter { input "$junos-input-filter"; output "$junos-output-filter"; } unnumbered-address lo0.0; } } } } } } interfaces { ge-1/0/0 { description ge0-1-0.dis4.xxxxxxxxxx; vlan-tagging; encapsulation flexible-ethernet-services; unit 404 { description xxxxxxxxx; vlan-id 404; family pppoe { duplicate-protection; dynamic-profile PPPOE; short-cycle-protection; } } } } access { radius-server { Xx.xxx.xx.xxx { secret “xxxxxxxxxxx"; ## SECRET-DATA source-address xx.xx.xxx.xx; } Xx.xxx.xxx.xx { secret “xxxxxxxxxxx"; ## SECRET-DATA source-address xx.xxx.xx.xx; } } group-profile DNS { ppp { primary-dns xxx.xxx.xx.xxx; secondary-dns xx.xx.x.xxx; } } profile RADIUS { accounting-order radius; authentication-order radius; radius { authentication-server [ xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx ]; accounting-server [ xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx ]; options { revert-interval 0; client-authentication-algorithm round-robin; client-accounting-algorithm round-robin; } } accounting { order radius; accounting-stop-on-failure; accounting-stop-on-access-deny; immediate-update; update-interval 10; statistics volume-time; } } address-assignment { pool PPPOE-1 { link PPPOE-2; family inet { network 10.0.0.0/24; range 1 { low 10.0.0.1; high 10.0.0.254; } } } } } } access-profile RADIUS; Also note that this example doesn’t include anything for your routing. So everything in JunOS is “access-internal” and you need to redistribute them into OSPF (or whatever IGP you are running). When you redistribute them, each route shows up separately for each subscriber - a large amount of /32 routes if you are not careful which can cause “bad things to happen(™)”. What I did to work around this was to summarize the routes but in doing so I had to ensure that static IP assignments would still function: routing-options { static { route 10.0.0.0/24 discard; } } policy-options { term access-internal-1 { from { protocol access-internal; route-filter 10.0.0.0/24 longer; then reject; } term access-internal-2 { from protocol access-internal; then accept; } term implicit-deny { then reject; } } } Hope that helps...
