Example:
Configuration Priorities
Foreground interface configuration takes priority over configuration inherited by the
interface through the interface-range.
interfaces {
interface-range range-1 {
member-range ge-1/0/0/ to ge-10/0/47;
mtu 256;
}
ge-1/0/1 {
mtu 1024;
}
}
In the preceding example, interface ge-1/0/1 will have an MTU value of 1024.
This can be verified with output of the show interfaces | display inheritance command,
as follows:
user@host: # show interfaces | display inheritance
## 'ge-1/0/0' was expanded from interface-range 'range-1'
##
ge-1/0/0 {
##
## '256' was expanded from interface-range 'range-1'
##
mtu 256;
}
ge-1/0/1 {
mtu 1024;
}
##
## 'ge-1/0/2' was expanded from interface-range 'range-1'
##
ge-1/0/2 {
##
## '256' was expanded from interface-range 'range-1'
##
mtu 256;
}
.........
.........
##
## 'ge-10/0/47' was expanded from interface-range 'range-1'
##
ge-10/0/47 {
##
## '256' was expanded from interface-range 'range-1'
##
mtu 256;
}
Member Interfaces Inheriting Configuration from Configuration Groups
Interface range member interfaces inherit the config-groups configuration like any other
foreground configuration. interface-range is similar to any other foreground configuration
statement. The only difference is that the interface-range goes through a member
interfaces expansion before Junos OS reads this configuration.
