RE: SDH Fiber Problem

I have been trying to create EoS however am getting the following:

I can ping on point to point I have BGP up and running

When I try to pass traffic over the link my clients are unable to pass any meanigful traffic asn browsing is impossible.

Any assistance  and direction in terms of any Fiber/SDH forums will be greatly appreciated.

Is this SDH router to router, or are you handing it off as Ethernet? I had a similar problem, and it was simply a mismatched duplex setting. -Keith
