Re: Bonded PPPoE over bridged DSL lines with multilink PPP
[In reply to]
|
|
Okay, I got this to work, for a given value of working. Adding ppp
multilink to the virtual template on the 7206 and removing the minimum
links entry on the 2600 led to the connection coming up with both ends
showing both links bundled into one MLP bundle, and I was able to ping
both directions across the bundle fine. Unfortunately, inexplicably,
the 2600, which had its default route set to "ip route 0.0.0.0 0.0.0.0
Dialer1" began ignoring the default route. It could ping the local
lan, could ping the 7206, but given an IP address that was not
directly connected, it would respond no route to host.
This is close to working. Can anyone offer any ideas about what might
have been causing this?

multilink PPP
Okay. At one end is a 2620 running 12.3(15) IPBase, with a 4NME card.
At the other is a 7206. Between them are three DSL lines, all running
in bridged mode. Two are bonded together between the DSL modem and the
DSLam, so essentially, we have two long Ethernet lines, plugged into
ports ethernet1/0 and ethernet1/1 on the 2620.
/--------C1 ~~~~\
A ~~~~~~~ B< > D
\========C2 ~~~~/
A (Cisco 7206, FE2/0)
B (Zhone Bitstorm)
~ (ethernet link)
- (single DSL line)
= (bonded DSL lines)
D (Cisco 2620, 4NME card, E1/0 and E1/1)
Essentially it all seems to work, turning it up with one port binds
virtual access 1 to the multilink PPP connection. But when both ports
on turned up on the 2620, it binds the second port, but then the
second port begins to go up and down and massive packet loss starts
occuring. It's not the DSL line, we tried both lines separately in
port 1, but work great. It's not the port, the same problem occurs if
we using ethernet1/2 as the second port, instead of E1/1. I was just
guessing at the config to make this work and I may have done it
completely wrongly.

"The problem with our concept of mind is that we confuse our own kind
of self-awareness with thinking in general. Self-awareness is an
attribute of certain kinds of social animals. Why should a mind be
self-aware? It's enough it's world-aware. If it isn't socially
connected to other minds, it doesn't need social filters or
self-modeling. It's self-making, self-sufficient. It embodies and
acts. A world-aware mind is just one step closer to God than you and
I."
