Pbr Rules - Avaya G430 Manual

Policy-based routing
4. Apply the PBR list to an interface.
5. Apply the PBR list to the Loopback interface.
6. Enter copy running-config startup-config.

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.
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
592 Administering Avaya G430 Branch Gateway
This example demonstrates a case where the data traffic is sent over the WAN
FastEthernet Interface through the Internet.
When the track detects that this next hop is not valid, traffic is routed over the
external Serial interface connected to the external Layer 3 router.
Enter exit to return to general context. From general context, enter the interface
to which you want to apply the PBR list. In the interface context, enter ip pbr-
group, followed by the number of the PBR list, to attach the list to the interface.
The list will be applied to packets entering the interface.
The following example applies PBR list 802 to VLAN 2.
Gxxx-001(super)# interface vlan 2
Gxxx-001(super-if:VLAN 2)# ip pbr-group 802
Done!
Gxxx-001(super-if:VLAN 2)#
The following example applies PBR list 802 to the Loopback interface.
Gxxx-001(super)# interface Loopback 1
Gxxx-001(super-if:Loopback 1)# ip pbr-group 802
Done!
Gxxx-001(super-if:Loopback 1)# exit
Gxxx-001(super)#
This saves the new policy-based routing configuration in the startup configuration
file.
