OK, Got a weird one.
Broadwing MPLS between two sites each having full DS3 access into 3662 router each site. was installed in November.
Do not have any baselines to go by, but at first we did get a good copy of SANs data several times across the link and seems ran about 30-35 mbps throughput, this was before Christmas.
Sometime around the first of the year we had MTU issues on the broadwing MPLS net, they had replaced hardware and had an incorrect MTU setting. Since that was fixed seems that we get very low bandwidth, varies between 2mpbs and will jump sometimes to 10-13 mbps and back down to different rates in between. Not seeing any errors on the circuits. Broadwing has went over their network and routers at great lengths.
Is their anything I can look at on the routers to see if anything on our routers configured wrong or other errors, etc ?
I can post configs, just do not have access to the routers until morning.
As mentioned, seemed like was working, and not after the MTU fix and we keep blaming broadwing but need to be 100 percent not on our end, Although I can not find anything wrong. Also router CPU is 3-5 percent total on each at the most. no interface ACL's, just a few for routing redistribution but just a few.
I'll take any suggestions to look at anything.
Thanks,
MC
