Pbr Rules; Overview Of Rule Criteria - Avaya G250 Administration

PBR rules

Each PBR list can have up to 1,500 rules. The first rule that matches the packet specifies the
next hop list for the packet. If no rule matches the packet, the packet is routed according to the
default rule.
This section provides information on how to configure rules in a PBR list and contains the
following topics:

Overview of rule criteria
You can configure policy rules to match packets based on one or more of the following criteria:
Source IP address, or a range of addresses
●
Destination IP address or a range of addresses
●
IP protocol, such as TCP, UDP, ICMP, IGMP
●
Source TCP or UDP port or a range of ports
●
Destination TCP or UDP port or a range of ports
●
ICMP type and code
●
Fragments
●
DSCP field

Note:
The fragment criteria is used for non-initial fragments only.
Note:
Use IP wildcards to specify a range of source or destination IP addresses. The zero bits in the
wildcard correspond to bits in the IP address that remain fixed. The one bits in the wildcard
correspond to bits in the IP address that can vary. Note that this is the opposite of how bits are
used in a subnet mask.
Note:
When you use destination and source ports in a PBR rule, policy-based routing
Note:
does not catch fragments.
