Configuring Interfaces Using JUNOS Configuration Groups
You can use configuration groups to separate
the common interface media parameters from the interface-specific
addressing information. The following example places configuration
data for ATM interfaces into a group called atm-options:
- [edit]
- user@host# show
- groups {
-
- atm-options {
-
- interfaces {
-
- <at-*> {
-
- atm-options {
- vpi 0 maximum-vcs 1024;
- }
-
- unit <*> {
- encapsulation atm-snap;
- point-to-point;
- family iso;
- }
- }
- }
- }
- }
- apply-groups atm-options;
- interfaces {
-
- at-0/0/0 {
-
- unit 100 {
- vci 0.100;
-
- family inet {
- address 10.0.0.100/30;
- }
- }
-
- unit 200 {
- vci 0.200;
-
- family inet {
- address 10.0.0.200/30;
- }
- }
- }
- }
- [edit]
- user@host# show | display inheritance
- interfaces {
-
- at-0/0/0 {
- ##
