P-791R v2 Support Notes
Cost Savings- IPPR allows organizations to distribute interactive traffic on
high-bandwidth, high-cost path while using low-path for batch traffic.
Load Sharing- Network administrators can use IPPR to distribute traffic
among multiple paths.

How does the IPPR work?
A policy defines the matching criteria and the action to take when a packet
meets the criteria. The action is taken only when all the criteria are met. The
criteria include the source address and port, IP protocol (ICMP, UDP, TCP,etc),
destination address and port, TOS and precedence (fields in the IP header)
and length. The inclusion of length criterion is to differentiate between
interactive and bulk traffic. Interactive applications, e.g., Telnet, tend to have
short packets, while bulk traffic, e.g., file transfer, tends to have large packets.
meets the criteria. The action is taken only when all the criteria are met. The

and length. The inclusion of length criterion is to differentiate between
interactive and bulk traffic. Interactive applications, e.g., Telnet, tend to have
short packets, while bulk traffic, e.g., file transfer, tends to have large packets.
The actions that can be taken include routing the packet to a different gateway
(and hence the outgoing interface) and the TOS and precedence fields in the
IP header. IPPR follows the existing packet filtering facility of ZyNOS in style
and in implementation. The policies are divided into sets, where related
policies are grouped together. A use defines the policies before applying them
to an interface or a remote node, in the same fashion as the filters. There are
12 policy sets with 6 policies in each set.

Setup the IP Policy Routing
Rules can be edited in SMT menu 25.
Suppose we’d like to edit the rule like this:
Policy Set Name=Test
Active= Yes
Criteria:
IP Protocol = 6
Type of Service= Don't Care Packet length= 0
Precedence = Don't Care Len Comp= N/A
Source:
addr start= 192.168.1.2 end= 192.168.1.20
port start= 0 end= N/A
Destination:
addr start= 0.0.0.0 end= N/A
port start= 80 end= 80
Action= Matched
Gateway addr = 192.168.1.254 Log= No
Criteria:
