I'm having problems getting IRB to work correctly with COVAD DSL
connected PVCs over Frame-Relay. (Configs below)
Everything seems to work fine on these connections - I can ping the
customer, simple stuff works, and all downloads in the direction of
the customer work, but when they try to FTP stuff upstream, or send an
encoded e-mail attachment, their transfers putter out during upload.
This is only on the *bridged* COVAD PVC's, not the routed ones (of
which we have a dozen or so on the same shared T1).
I'm running 12.0(6) in a MC3810 with 32 MB of RAM. The customers are
using FlowPoint 2200 SDSL router/bridge at varying speeds in bridged
ADSL mode. Line problems have been eliminated as a problem. Is there
a switch I'm not flipping, or something I'm forgetting, or is there an
issue with using this type of configuration in a MC3810? I get this
problem whether or not I'm using separate sub-interfaces with separate
BVI's, or whether I share.
