I have redhat 6.1 "out of the box" which has the ppp 2.3.10-3 driver
and connected two modems to ttys0 and ttys1, set both through linuxconf
to dial my Cisco 2511 and turned it on.
both interfaces came up and dialled and connected, multilink appeared to
work perfectly.
Then I tried some fault tolerance I turned off one modem, and the link
failed to route completely, even though the other modem was still
connected fine.
Am I right in assuming that the first modem to connect get "designated"
the primary of the two and carries all of the back channel (upstream)
data, whilst the second modem simply acts as a secondary channel to
assist in receiving every other packet ?
hmmm, I just tired doing it the other way around and switching off the
other modem instead (after the first had redialled again), once again
the remaining modem failed to route, so it appears that if either modem
fails then regardless of wether the other is connected or not the
multilink fails.
I don't want to sound dumb, just trying to understand the system before
I give it to a customer so I know what to expect.
