Ok, so we have a 2811 router configured with a multilink frame interface which combines 3 full T1's into the router (all WIC's exactly the same). This is then fragmented out to WAN units at varying speeds. All this has been running just fine for the past 3 weeks (we replaced the router 3 weeks ago and setup the MFR). All of a sudden last week, we started losing eigrp adjacency which disconnected our WAN units juuust long enough to crash the only application they use (via citrix). Our Telco is involved and they swear up and down that there is no problem with their circuits. We spent all day Thursday and Friday last week trying to remedy this. We applied traffic shaping to the MFR sub-interfaces and this *seemed* to stabalise things for 1/2 a day or so. Then yesterday the whole thing started bouncing again. So the burning question is..is this a problem with our router /setup or is it a telco problem?
I've pasted our host router config, MFR stats and fram stats below. ANY suggestions or advice would be greatly appreciated!!
Thanks in advance!!
