	This is a problem because igp issues:

nnn-7202(config)#router ospf 1
nnn-7202(config-router)#maximum-paths ?
  <1-6>  Number of paths

	Because of this, you are unable to hanle those multiple paths
past 6.

	You also have the same isues with isis:
nnn-7202(config)#router isis home1
nnn-7202(config-router)#maximum-paths ?
  <1-6>  Number of paths

	I don't have a pdf viewer (on this machine), so can't cite this 
right now, but I think that the dl imux will handle up to 8 E1's:
