Configuring Integrated Routing and Bridging in ACX Series
Integrated routing and bridging (IRB) provides simultaneous support for Layer 2 bridging
and Layer 3 routing on the same interface. IRB enables you to route packets to another
routed interface or to another bridge domain that has an IRB interface configured. You
configure a logical routing interface by including the irb statement at the [edit interfaces]
hierarchy level and include that interface in the bridge domain. For more information
about how to configure a routing interface, see the Junos OS Network Interfaces Library
for Routing Devices.
NOTE: You can include only one routing interface in a bridge domain.
The following are the list of features supported for IRB:
•
Family inet, inet6, and iso are supported on an IRB interface.
•
Routing protocols supported on an IRB interface are BGP, ISIS, OSPF, RIP, IGMP, and
PIM.
•
DHCP Relay with option 82 is supported on an IRB interface.
•
IRB can be added in a VRF routing instance.
•
VRRP is supported on an IRB inteface.
•
Bidirectional Forwarding Detection (BFD) protocol is supported on an IRB interface.
•
The following Class-of-Service configurations are supported on an IRB interface:
•
The IRB classifiers and rewrite on routed packets.
•
Fixed classifier can be applied on an IRB logical interface.
•
Firewall filters (multifield filter) can be used to assign forwarding class and loss
priority. You should define a family inet or inet6 filter and apply it as the input filter
on an IRB logical interface under family inet.
NOTE: physical-interface-filter is not supported for family inet6 filter on
IRB logical interface.
