[nsp] 'permanent' keyword in 'ip route'....

[Marcus Keane]

No, it means the router doesn't care if the next hop is up or not. See
below.

Looking at other routers that also use the term 'permanent', I would
guess that it means that this (static!) route cannot be overriden by a
dynamic route (learned from a router protocol, i.e. RIP, OSPF, EIGRP).
