Multipoint PPP on PPPoE link?

Stupid question - is it possible to run a Multipoint-PPP on a PPPoE link
in order to bundle multiple DSL lines?

Tnx, -gg

Nope. The DSL provider would have to run MLPPP with you.

I'm the DSL provider, too ...

Sorry ... only in German. But it should work for you, Garry.

btw: I guess the correct terminus is "multilink ppp". It's always two
points ...

Well, I got it working, kind of ... I have multiple l2tp dialins to our
router up, using MPP as protocol in Radius, using "ppp multilink" on the
dialer profile ... here's the dialer config:

interface Dialer2
mtu 1492
bandwidth 2048
ip address negotiated previous
ip load-sharing per-packet
encapsulation ppp
ip tcp adjust-mss 1416
no ip mroute-cache
dialer pool 2
dialer-group 2
tag-switching mtu 1452
tag-switching ip
ppp authentication chap pap callin dsldialin
ppp chap hostname x
ppp chap password x
ppp pap sent-username x password x
ppp multilink

I have no packet loss, BGP comes up just fine, but somehow, only one
channel is mainly used, and even multiple downloads from different
destinations don't give me the expected bandwidth ...

Here's the radius profile I use,

x Auth-Type == Local, Password == "x"
Session-Timeout := `%{expr:86400 - ((%l - 3600) %% 86400)}`,
Service-Type := Framed-User,
Framed-IP-Address := 212.218.63.18,
Framed-Netmask := 255.255.255.252,
Framed-Protocol := MPP,
Cisco-Avpair -= "lcp:interface-config",
Cisco-Avpair += "lcp:interface-config=descr 3M ADSL Backup",
Cisco-Avpair += "lcp:interface-config=ip unnumbered lo1",
Cisco-Avpair += "lcp:interface-config=tag-switching ip",
Cisco-Avpair += "lcp:interface-config=mtu 1492",
Cisco-Avpair += "lcp:interface-config=bandwidth 3072",
Cisco-Avpair += "lcp:interface-config=tag-switching mtu 1452",
Cisco-Avpair += "lcp:interface-config=ip tcp adjust-mss 1412",
Cisco-Avpair += "lcp:interface-config=no ip mroute-cache"

"show int viXX conf" on the l2tp dialin router results in this:

Virtual-Access18 is an VPDN link (sub)interface

Derived configuration : 317 bytes
!
interface Virtual-Access18
description 3M ADSL Backup
mtu 1492
bandwidth 3072
ip unnumbered Loopback1

timeout absolute 905 54
tag-switching mtu 1452
tag-switching ip
peer default ip address pool dsl-pool
keepalive 60
down-when-looped
ppp authentication chap pap callin
end

Show int dia2 on the dial-out router gives me this when connected:

while both channels show some traffic, all my ping traffic ends up on
one link ... Also, wondering about the "multilink" not showing up on the
other side's Virtual interface config, while on the dialout-router, it
is shown:

#show int vi23 conf
Virtual-Access23 is a PPP over Ethernet link (sub)interface

Derived configuration : 346 bytes
!
interface Virtual-Access23
no ip address
pulse-time 0
ppp authentication chap pap callin tonline
ppp chap hostname fd-gw1#(E-Mail Removed)
ppp chap password 7 1515021E057B7A21
ppp pap sent-username fd-gw1#(E-Mail Removed) password 7
13021E000A5D552F
ppp multilink
end

#show int vi24 conf
Virtual-Access24 is a PPP over Ethernet link (sub)interface

Derived configuration : 346 bytes
!
interface Virtual-Access24
no ip address
pulse-time 0
ppp authentication chap pap callin tonline
ppp chap hostname fd-gw1#(E-Mail Removed)
ppp chap password 7 1515021E057B7A21
ppp pap sent-username fd-gw1#(E-Mail Removed) password 7
13021E000A5D552F
ppp multilink
end


Any idea? Help appreciated ...

I would be interested to know how (or why) you came up with the
various MTU settings in your config. I understand the 1492 for DSL,
and a respective MSS for that would be 1452. Just curious....

Oops --- a left-over from a test via GRE tunnel ... should read 1452,
too ... didn't change anything though ... (as would be expected ...)
