If I understand you correctly, you are saying they receive 
some 60 routes from their exchange point peering router on 
their transit router, right?

Unless they have a particular reason for this, they really 
should be filtering this in the core, as any 
misconfiguration could send these 60 routes to their transit 
provider, thus, offering potential transit to the exchange 
point members.

But anyway...

Well the configuration posted shows IOS 12.4, so it should 
be relatively decent :-).

Do you have a 'sh ip bgp' output?

Does 'sh ip route' on any of the other iBGP routers show the 
same issue?

There's not much to go on here?

Need more info. Hard to say whether the posted configuration 
is from the exchange point peering router or the transit 
router.

Cheers,

Mark.
