Attaching A Pbr List To An Interface - Avaya G350 Administration

The following example creates PBR list 802 and assigns it the name Data:
G350-001# ip pbr-list 802
G350-001(if:pbr-list 802)# name "Data"
PBR lists do not have a default next hop list. If you do not define a next hop list for the PBR list, or if no
rule matches the packet, the packet is routed according to destination-based routing (DBR).
To delete a PBR list, type
NOTE:
You cannot delete or modify a PBR list when it is attached to an interface. In order to
change or delete a list that is attached to an interface, you must first remove the list from
the interface. You can then change or delete the list. After changing the list, you can
reattach the list to the interface.

Attaching a PBR list to an interface

Policy-based routing takes place only when the packet enters the interface, not when it leaves. Policy-
based routing takes place after the packet is processed by the Ingress Access Control List and the Ingress
QoS list. Thus, the PBR list evaluates the packet after the packet's DSCP field has been modified by the
Ingress QoS List. See
When no PBR list is assigned to the interface, or when the rules defined in the PBR list do not match the
packet, the packet is routed according to DBR.
To attach a PBR list to an interface, enter the interface context and type
For example, the following sequence of commands attaches PBR list 801 to VLAN 2:
G350-001# interface Vlan 2
G350-001(if:Vlan 2)# ip pbr-group 801
Done!
NOTE:
It is strongly recommended to enable extended keepalive on any interface that is using
policy-based routing. Extended keepalive provides the interface with the ability to
determine whether a next hop is or is not available more quickly than by ordinary routing
protocols. See
To remove a list from an interface, use the
remove the PBR list from the VLAN interface by typing the following commands:
G350-001# interface Vlan 1
G350-001(if:Vlan 1)# no ip pbr-group
Done!
