1. Enable MPLS and RSVP on Routers

Action

To enable MPLS and RSVP on routers in your network, follow these steps:

1. In configuration mode, go to the following hierarchy level:

[edit]

user@host# edit protocols 

2. Configure MPLS and RSVP:

[edit protocols]

user@host# set mpls interface all

user@host# set rsvp interface all

3. Disable the management interface for MPLS and RSVP:

[edit protocols mpls]

user@host# set interface fxp0.0 disable

[edit protocols rsvp]

user@host# set interface fxp0.0 disable

4. Verify and commit the configuration:

user@host# show

user@host# commit 

Sample Output

user@R1> edit

Entering configuration mode

[edit]

user@R1# edit protocols

[edit protocols]

user@R1# set mpls interface all 

[edit protocols]

user@R1# set rsvp interface all 

[edit protocols]

user@R1# show 

rsvp {

    interface all;

    interface fxp0.0 {

        disable;

    }

}

mpls {

    interface all;

    interface fxp0.0 {

        disable;

    }

}

[edit protocols]

user@R1# commit 

commit complete

What It Means

The sample output shows that router R1 has MPLS and RSVP enabled on all interfaces, except for the management interface (fxp0.0), which is disabled. It is considered best practice to disable the management interlace (fxp0.0) for MPLS and RSVP to preempt any problems. The sample network shown in Figure 1 has all interfaces (with the management interface [fxp0.0]) disabled on all routers configured with the MPLS and RSVP protocols.

Typically every interface that you want to use is listed. For an example of a router configured with specific interfaces, see Enable IS-IS on Routers in Your Network.
