FAQ- How Can the NE5000E Flexibly Control the Route Information Receiving and Sending Through Matching the IP-Prefix List with the Mask Lengths

Publication Date:  2012-07-27 Views:  94 Downloads:  0
Issue Description
Q:
How can the NE5000E flexibly control the route information receiving and sending through matching the IP-prefix list with the mask lengths? 
 
Alarm Information
Null
Handling Process
 A:
For the ip ip-prefix default-router index 10 permit 0.0.0.0 0, the mask 0 indicates 0.0.0.0. You can adopt this method when designing a default route policy.
For ip ip-prefix default-router index 10 permit 0.0.0.0 32, the mask 32 indicates that only the address with a 32-bit mask is matched. You can adopt this method when attempting to refer or filter the detailed 32-bit routes.
For ip ip-prefix default-router index 10 permit 0.0.0.0 30, greater-equal 30 less-equal 32 indicates that all the addresses and network segments whose mask lengths range from 30 to 32 bits can be matched. You can adopt this method to filter or match the routes whose mask lengths range from 30 to 32 bits on the network.
For the ip ip-prefix default-router index 10 permit 202.0.0.0 8, greater-equal 30 less-equal 32 indicates that the addresses and network segments whose mask lengths range from 30 to 32 bits and beginning with 202 can be matched.
