No, you need this one .. or at least, it's what worked for me. From my
mpd.conf, with comments I added when I was also getting redial to work:
# without, 'noretry' was ENABLED (so no redial!)
set bundle disable noretry
and
# without, 'Max redial:no redial' (-1); 0 = 'Max redial:unlimited'
set link max-redial 0

Yep.

Yes, that works fine until you lose the link :)

Hmm, well 'set bundle disable noretry' is what worked for me here. Are
you sure you restarted mpd afresh after changing that? I recall having
found something in update/changelog notes regarding the default value
having changed for this, and after showing numerous values via console.

Here's my working mpd.conf; note that I'm still on mpd-4.1 though, fwiw,
otherwise it's little different from yours.
PPPoE:
new bPPPoE lPPPoE
set iface addrs 1.1.1.1 2.2.2.2
set iface route default
set iface disable on-demand
set iface idle 0
set iface up-script /root/bin/mpd_up
set iface down-script /root/bin/mpd_dn
# needed? seems so, t23 had trouble with large tcp pkts .. yep, fixes ..
set iface enable tcpmssfix
set bundle disable multilink
# without, 'noretry' was ENABLED (so no redial!)
set bundle disable noretry
set auth authname "yeahright"
set auth password "uhuh"
set link no acfcomp protocomp
set link disable pap chap
set link accept chap
set link mtu 1492
set link keep-alive 10 60
# without, 'Max redial:no redial' (-1); with, 'Max redial:unlimited'
set link max-redial 0
set ipcp yes vjcomp
set ipcp ranges my.ipa.ddr.ess/0 220.233.0.0/16
# log dns servers as info anyway .. only passed to up-script, called as:
# up: script interface proto local-ip remote-ip authname [dns1 ip] [dns2 ip]
# where 'dns1' and 'dns2' are LITERAL STRINGS $6 and $8 (dox need work!)
# dn: script interface proto authname
# later 6/3/7 which works, but we know these anyway .. ah why not ..
set ipcp enable req-pri-dns
set ipcp enable req-sec-dns
open
mpd.links (note 'set link type' for 4.1, your 'set phys type' for 4.2)
lPPPoE:
set link type pppoe
set pppoe iface xe0
set pppoe service ""
set pppoe disable incoming
set pppoe enable originate
