[j-nsp] Prefix prioritization support on Juniper

[Stacy W. Smith]

Prefix prioritization for OSPF-learned prefixes is supported since  
JUNOS 9.3, and the order in which LDP-learned prefixes are installed  
corresponds to the order in which the corresponding OSPF-learned  
prefixes were installed.

See the bottom of this page for configuring prefix prioritization for  
OSPF:

http://www.juniper.net/techpubs/software/junos/junos95/swconfig-routing/id-11721665.html#id-11721665

You can confirm the results of your routing policy by checking the  
output of 'show ospf route detail'.

user at host> show ospf route detail | match "Network|priority"
10.0.3.0/30        Intra  Network     IP       10  so-2/1/2.0
   area 0.0.0.0, origin 10.255.70.17, priority medium <<<<<<<<<<<<<<<<<
10.1.3.0/30        Intra  Network     IP        5  so-2/1/2.0
   area 0.0.0.0, origin 10.255.70.19, priority medium <<<<<<<<<<<<<<<<<
