Example: Configuring Filtering of Frames by Packet Loss Priority
To configure an MX Series router firewall filter to provide matching on the packet loss
priority (PLP) level carried in the frame, use the
loss-priority
or
loss-priority-except
match
condition. Packet loss priority matching is available for all protocols. For more detailed
information about configuring firewall filters and configuring filter match conditions for
Layer 2 bridging traffic on the MX Series routers, see the Routing Policy Configuration
Guide.
NOTE:
Layer 2 bridging is supported only on the MX Series routers. For more
information about how to configure Layer 2 bridging, see the Junos® OS
Network Interfaces, the Junos OS Routing Protocols Configuration Guide,
and the Junos OS Feature Guides.
This example Layer 2 bridging firewall filter finds any incoming frames with a packet loss
priority (PLP) level of
medium-high
, and then classifies the packet in the
expedited-forwarding
default forwarding class.
NOTE:
This example does not present exhaustive configuration listings for
all routers in the figures. However, you can use this example with a broader
configuration strategy to complete the MX Series router network Ethernet
Operations, Administration, and Maintenance (OAM) configurations.
