Add Multiple Tunnels

You can provision multiple tunnels at once in the network topology from the Add Multiple Tunnels page.

To provision multiple tunnels:

  1. Select Network > Topology.

    The Topology page appears.

  2. In the Tunnel tab, select Add > Multiple Tunnels.

    The Add Multiple Tunnels page appears.

  3. Complete the configuration on each tab according to the guidelines in Table 1.
    Note:

    Fields marked with an asterisk (*) are mandatory.
  4. Click Add.

    A confirmation message appears on the top of the page, indicating that an add tunnel request was successfully created.

    The tunnels then appear in the Tunnel tab of the network information table on the Topology page.

Field

Description

Properties

ID Prefix

Specify a prefix to be applied to the names of all the tunnels that are created.

Node A List

Select one or more nodes to be part of the Node A list.

For a full mesh tunnel to be created, you can specify the same nodes for Node A and Node Z by clicking the Copy Node Z List link (that is located above the list). All the nodes that you specify in the Node Z List are added to the Node A List.

Node Z List

Select one or more nodes to be part of the Node Z list.

For a full mesh tunnel to be created, you can specify the same nodes for Node Z and Node A by clicking the Copy Node A List link (that is located above the list). All the nodes that you specified in the Node A List are added to the Node Z List.

Planned Bandwidth

Specify the planned bandwidth (along with valid units, with no space between the bandwidth and units) for the tunnel. If you specify a value without units, bps is applied.

Valid units are:

  • B or b (bps)

  • M or m (Mbps)

  • K or k (Kbps)

  • G or g (Gbps)

Examples: 50M, 1000b, 25g.

Setup

Specify the setup priority for the tunnel traffic.

Priority levels range from 0 (highest priority) through 7 (lowest priority). The default is 7, which is the standard MPLS tunnel definition in Junos OS.

Based on the setup priority, the PCE determines whether a new tunnel can be established, by preempting an existing tunnel. The existing tunnel can be preempted if the setup priority of the new tunnel is higher than that of the existing tunnel and the preemption releases enough bandwidth for the new tunnel.

Hold

Specify the hold priority for the tunnel traffic.

Priority levels range from 0 (highest priority) through 7 (lowest priority). The default is 7, which is the standard MPLS tunnel definition in Junos OS.

Based on the hold priority, the PCE determines whether the tunnel can be preempted or not. If the hold priority for a tunnel is higher, it is unlikely for the tunnel to be preempted.
