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 Policy
Framework ConfigurationGuide,the JunosOSRoutingProtocolsConfiguration
Guide, and the Junos OS Feature Guide.
Thisexample Layer2 bridgingfirewallfilter finds any incoming frameswith anIEEE 802.1p
learned VLAN priority level ofeither 1or 2,and thenclassifies the packet in the best-effort
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.
To configure filtering of frames by IEEE 802.1p bits:
1.
Configure the firewall filter filter-learn-vlan-configure-forwarding:
[edit firewall]
family bridge {
filter filter-learn-vlan-configure-forwarding {
term 0 {
from {
learn-vlan-1p-priority [1 2];
}
then forwarding-class best-effort;
}
}
}
2.
Apply the firewall filter filter-learn-vlan-configure-forwarding as an input filter to
ge-0/0/0:
[edit interfaces]
ge-0/0/0 {
unit 0 {
family bridge {
filter {
input filter-learn-vlan-configure-forwarding;
}
}
}
}
