Configuring LMP and an LMP Neighbor

Configuring LMP and an LMP Neighbor

LMP and an LMP neighbor are configured on an edge node on a transport network and an IP network to manage the data and control channels and detect link connectivity.

Context

GMPLS uses LMP to manage links of the control and data channels. LMP is classified into the following types:

  • Static LMP: LMP neighbors, control channels, and data channels are manually configured, without exchanging LMP packets.
  • Dynamic LMP: LMP neighbors, control channels, and data channels are all automatically discovered, which minimizes configurations and speeds up network deployment.

Currently, the NE40E supports only static LMP. Perform the following steps to configure LMP and a neighbor on an edge node:

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    lmp

    The global LMP view is displayed.

  3. Run:

    peer name

    An LMP neighbor is created.

    NOTE:
    The neighbor of an IP network edge node is a transport network edge node that directly connects to the IP network edge node. This means that LMP neighbor relationships are created between the ingress EN and ingress CN, and between the egress EN and egress CN.

  4. Run:

    lmp static

    The working mode of an LMP neighbor is set to static LMP.

  5. Run:

    node-id ip-address

    An IP address is assigned to the LMP neighbor.

    The ingress EN's LMP neighbor is the ingress CN on an optical network, and the egress EN's LMP neighbor is the egress CN on the optical network. The ip-address parameter is set to the node ID of the ingress CN or egress CN.

  6. Run:

    te-link te-link-id

    A data-link is created between LMP neighbors.

    A TE-link is a bundle of data-links that directly connected LMP neighbors.

  7. Run:

    link-id local ip ip-address

    A local TE-link ID is set.

  8. Run:

    link-id remote ip ip-address

    A remote TE-link ID is set.

  9. Run:

    data-link interface interface-type interface-number local interface-id ip-address remote interface-id ip-address

    A data-link is bound to a TE-link.

  10. Run:

    commit

    The configuration is committed.
