Check the Administrative Group Configuration on R5
Purpose
Focus on R5 to determine which interfaces are associated with the red color, and make any necessary corrections.
Action
To check the administrative group configuration on R5 and make any necessary corrections, enter the following Junos OS CLI commands:
user@R5> edit
[edit protocols mpls]
user@R5# show
user@R5# delete interface so-0/0/1 admin-group
user@R5# set
interface so-0/0/0 admin-group red
user@R5# show
user@R5# commit
Sample Output 1
user@R5> edit
Entering configuration mode
[edit protocols mpls]
user@R5# show
admin-groups {
red 8;
}
interface fxp0.0 {
disable;
}
interface so-0/0/0.0;
interface so-0/0/1.0 { <<<incorrect interface configured with admin-group
admin-group red;
}
interface so-0/0/2.0;
Sample Output 2
[edit protocols mpls]
user@R5# delete interface so-0/0/1 admin-group
[edit protocols mpls]
user@R5# set interface so-0/0/0 admin-group red
[edit protocols mpls]
user@R5# show
admin-groups {
red 8;
blue 4;
}
interface fxp0.0 {
disable;
}
interface so-0/0/0.0 { <<<correct interface configured with admin-group
admin-group red;
}
interface so-0/0/1.0;
interface so-0/0/2.0;
[edit protocols mpls]
user@R5# commit
commit complete
Sample Output 3
user@R1> show mpls lsp Ingress LSP: 1 sessions To From State Rt ActivePath P LSPname 10.0.0.6 10.0.0.1 Up 1 * R1-to-R6 Total 1 displayed, Up 1, Down 0 Egress LSP: 1 sessions To From State Rt Style Labelin Labelout LSPname 10.0.0.1 10.0.0.6 Up 0 1 FF 3 - R6-to-R1 Total 1 displayed, Up 1, Down 0 Transit LSP: 0 sessions Total 0 displayed, Up 0, Down 0
Meaning
Sample Output 1 from transit router R5 shows that at the [edit protocols mpls] hierarchy level, interface so-0/0/1 is incorrectly configured with the admin-group red statement. The so-0/0/0 interface should be configured with the admin-group red statement.
Sample Output 2 shows the steps taken to correct the configuration. The administration group has been deleted from so-0/0/1 and so-0/0/0 is now associated with the red color.
Sample Output 3 shows that LSP R1-to-R6 is established.
