[c-nsp] problem of both "ip route 0.0.0.0" and "ip default-gateway" configured

[Sami Joseph]

Hello,

Someone mentioned that configuring both commands on the same router/switch
causes trouble, i wonder if someone can help me understand why?

1) ip route 0.0.0.0 next-hop
2) ip default-gateway next-hop

Also why would configuring a couple of static routes with the next hop being
an interface name not an ip address cause high CPU ?

Thanks,
Sam
