•
Re-write can be applied only at the IRB interface level.
•
dscp, inet-precedence, ieee-802.1, and ieee-802.1ad values can be rewritten.
ACX routers do not support MPLS families on IRB.
IRB can be configured under the following hierarchies:
•
[edit intefaces irb interface_type] hierarchy level
•
disable—Disables the interface
•
gratuitous-arp-reply—Enables gratuitous ARP reply
•
hold-time—Hold time for link up and link down
•
mtu—Maximum transmit packet size (256..9192)
•
no-gratuitous-arp-reply—Does not enable gratuitous ARP reply
•
no-gratuitous-arp-request—Ignores gratuitous ARP request
•
[edit interfaces irb.unit family (inet | inet6 | iso)] hierarchy level
•
[edit bridge-domains routing-interface interface irb.unit] hierarchy level
•
[edit routing-instances instance-type vrf] hierarchy level
•
[edit protocols (bgp | isis | ospf | rip | igmp | pim) interface irb.unit] hierarchy level
•
[edit class-of-service interfaces irb]] hierarchy level
In ACX5048 and ACX5096 routers, you can configure IRB at the [edit vlans vlan-name]
l3-interface irb.unit; level.
NOTE: The Layer 2 CLI configurations and show commands for ACX5048
and ACX5096 routers differ compared to other ACX Series routers. For more
information, see “Understanding Layer 2 Next Generation Mode on ACX5048
and ACX5096 Routers” on page 1167.
To configure a bridge domain with IRB support, include the following statements:
[edit]
bridge-domains {
bridge-domain-name {
domain-type bridge;
interface interface-name;
routing-interface routing-interface-name;
vlan-id (none | number);
vlan-tags outer number inner number;
}
}
For each bridge domain that you configure, specify a bridge-domain-name. You must also
specify the value bridge for the domain-type statement.
For the vlan-id statement, you can specify either a valid VLAN identifier or the none option.
