Interfaces Inheriting Common Configuration
If an interface is a member of several interface ranges, that interface will inherit the
common configuration from all of those interface ranges.
[edit]
interfaces {
interface-range range-1 {
member-range ge-1/0/0 to ge-10/0/47;
mtu 256;
}
}
interfaces {
interface-range range-1 {
member-range ge-10/0/0 to ge-10/0/47;
hold-time up 10;
}
}
In this example, interfaces ge-10/0/0 through ge-10/0/47 will have both hold-time and
mtu.
Configuring Inheritance Range Priorities
The interface ranges are defined in the order of inheritance priority, with the first interface
range configuration data taking priority over subsequent interface ranges.
[edit]
interfaces {
interface-range int-grp-one {
member-range ge-0/0/0 to ge-4/0/40;
member ge-1/1/1;
/*Common config is added part of the interface-range definition*/
mtu 256;
hold-time up 10;
}
}
interfaces {
interface-range int-grp-two {
member-range ge-5/0/0 to ge-10/0/40;
member ge-1/1/1;
mtu 1024;
}
}
Interface ge-1/1/1 exists in both interface-range int-grp-one and interface-range int-grp-two.
This interface inherits mtu 256 from interface-range int-grp-one because it was defined
first.
Configuration Expansion Where Interface Range Is Used
In this example, interface-range range-1 is used under the protocols hierarchy:
