  • Page 23: Mpls Ttl Expiration Enable

    undo mpls mtu Default The MPLS MTU of an interface is not configured. Fragmentation for MPLS packets is based on the MTU of the interface, and the length of a fragment does not include that of the MPLS label. Thus, after an MPLS label is inserted into a fragment, the length of the MPLS fragment may exceed the interface MTU.

  • Page 24: Mpls Ttl Propagate

    Usage guidelines The mpls ttl expiration enable command enables an LSR to generate an ICMP TTL-expired message upon receiving an MPLS packet with TTL being 1. If the MPLS packet has only one label, the LSR sends the ICMP TTL-expired message back to the source through IP routing. If the MPLS packet has multiple labels, the LSR forwards the ICMP TTL-expired message along the LSP of the MPLS packet to the egress, which then sends the message back to the source.

  • Page 51: Lsr-Id

    Usage guidelines The default LSP generation policy depends on the label distribution control mode. In Ordered mode, LDP can only use the Loopback interface address routes with a 32-bit mask • and the routes with a 32-bit mask that match the FECs of label mappings received from downstream LSRs to generate LSPs.

  • Page 52: Maxhops

    LDP uses the same LSR ID for all sessions in the same VPN instance. After you configure a new LSR ID for a VPN instance, LDP does not use the new LSR ID unless you use the reset mpls ldp command to reestablish all LDP sessions in the VPN instance.

Usage guidelines LDP adds LSR ID information in a label request or label mapping message. Each LSR checks whether its LSR ID is contained in the message.

  • Page 60: Session Protection

    Usage guidelines Resetting an LDP session deletes and re-establishes the session and all LSPs based on the session. To apply new parameters except the MD5 authentication key to an LDP session, you must use this command to reset the LDP session. Examples # Reset all LDP sessions in the public network.

  • Page 61: Targeted-Peer

    When you enable the session protection function, you can specify the session protection duration. If the Link Hello adjacency does not recover within the duration, LDP deletes the Targeted Hello adjacency and the LDP session. If you do not specify the session protection duration, the two peers always maintain the LDP session over the Targeted Hello adjacency.
