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
Policy Framework 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
Framework Configuration Guide
, and the
Guide Junos OS Feature Guides
This example Layer 2 bridging firewall filter finds any incoming frames with an IEEE 802.1p
learned VLAN priority level of either 1 or 2, and then classifies the packet in the
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:
Configure the firewall filter
1.
[edit firewall]
family bridge {
filter filter-learn-vlan-configure-forwarding {
term 0 {
from {
learn-vlan-1p-priority [1 2];
}
then forwarding-class best-effort;
}
}
}
Apply the firewall filter
2.
:
ge-0/0/0
[edit interfaces]
ge-0/0/0 {
unit 0 {
family bridge {
filter {
input filter-learn-vlan-configure-forwarding;
}
}
}
}
