Problem:
One one end is a cisco 7206. It has an ethernet connection to a Zhone Bitstorm DSlam. 3 DSL connections leave the DSlam. One goes to one comtrend modem. The other two go to another comtrend modem in a bonded pair, so they act like one DSL line. Both comtrends operate in bridging mode,so essentially they are both long ethernet connections. One the other end is a Cisco 1720 running 12.4 and with a 4-port wic 4ESW, so, 4 ethernet ports in addition to the onboard fastethernet 0.
A (Cisco 7206, FE2/0)
B (Zhone Bitstorm)
~ (ethernet link)
- (single DSL line)
= (bonded DSL lines)
D (Cisco 1720, 4ESW card)
The original intent was simply that these two connections (effectively two long ethernet links) operate as a bonded ethernet connection using multilink PPP. But the four port ethernet card does not seem to allow that. So the problem is how to get the two ethernet connections coming out of the 1720 to act as one bonded ethernet connection. We tried adding a second 4ESW to the 1720under the assumption that would give us a second set of four ports in VLAN2, but it only seems to see one card at a time.
Suggestion solutions?
