Page 21: Mpls Lsr-Id
Specifies the egress to advertise an implicit null label of 3 to the penultimate hop. Usage guidelines If the penultimate hop supports PHP, HP recommends that you configure the egress to advertise an implicit null label to the penultimate hop. If you want to simplify packet forwarding on the egress but keep labels in packets for the egress to determine QoS policies, you can configure the egress to advertise an explicit null label to the penultimate hop.
Page 22: Mpls Mtu
Specifies an ID for identifying the LSR, in dotted decimal notation. Usage guidelines HP recommends that you use the address of a loopback interface on the LSR as the LSR ID. Examples # Configure the LSR ID as 3.3.3.3 for the local node.

IP TTL and label TTL. HP recommends that you set the same TTL processing mode on all LSRs of an LSP. To enable TTL propagation for a VPN, you must enable it on all PE devices in the VPN, so that you can get the same traceroute result (hop count) from those PEs.

Page 46: Graceful-Restart
Table 20 Command output Field Description Memory state: • Normal—The memory is normal. • Memory State Minor—The memory has a minor alarm. • Severe—The memory has a severe alarm. • Critical—The memory has a critical alarm. Number of Hellos discarded when the memory is in an alarm state. If no Hello Discarded Hellos is discarded, this filed is not displayed.
Page 47: Graceful-Restart Timer
Usage guidelines GR enables an LSR to retain MPLS forwarding entries during an LDP restart, ensuring continuous MPLS forwarding. The graceful-restart command does not take effect on LDP sessions established before the command is executed. To apply the new setting, execute the reset mpls ldp command to reestablish LDP sessions. Examples # Enable GR for LDP.
Page 48: Label-Distribution
When LDP restarts, the GR restarter starts the MPLS Forwarding State Holding timer, and marks the MPLS forwarding entries as stale. When a GR helper detects that the LDP session with the GR restarter is down, it marks the FEC-label mappings learned from the session as stale and starts the Reconnect timer, the value of which is received from the GR restarter.
Page 49: Loop-Detect
Predefined user roles network-admin mdc-admin Parameters independent: Specifies Independent label distribution mode. In this mode, an LSR can distribute label mappings to the upstream LSR at any time. ordered: Specifies Ordered label distribution mode. In this mode, an LSR distributes a label mapping for a FEC to the upstream LSR only when the LSR receives a label mapping for that FEC from the downstream LSR or the LSR is the egress node of that FEC.
Page 50: Lsp-Trigger
After you configure an LSP generation policy, LDP uses all routes or the routes permitted by the IP prefix list to generate LSPs, regardless of the label distribution control mode. HP recommends that you use the default LSP generation policy.
Page 51: Lsr-Id
LDP sessions in the VPN instance. For the public network, HP recommends that you use the default LDP LSR ID configured by the mpls lsr-id command. If you want to configure an LDP LSR ID for the public network by using the lsr-id command, specify the IP address of a local Loopback interface as the LDP LSR ID for high reliability.

Use undo mpls ldp to disable LDP globally for an LSR and delete all LDP-VPN instances. Syntax mpls ldp undo mpls ldp Default LDP is globally disabled. Views System view Predefined user roles network-admin mdc-admin Usage guidelines You must enable LDP globally for an LSR to run LDP. The GR commands, the session protection command, and the targeted-peer command are available only in LDP view.
Page 55: Mpls Ldp Timer
Predefined user roles network-admin mdc-admin Usage guidelines Before you enable LDP on an interface, use the mpls ldp command in system view to enable LDP globally. Disabling LDP on an interface terminates all LDP sessions on the interface, and removes all LSPs established through the sessions.
Page 56 If the Hello hold time and the Keepalive hold time values are too large, LDP cannot quickly detect link failures. If the values are too small, LDP might mistakenly consider a normal link failed. HP recommends that you use the default values.

Page 58: Pv-Limit
Using mpls ldp transport-address in LDP peer view, you specify the transport address carried in the Targeted Hellos sent to the LDP peer. HP recommends that you use the default transport address. If two LSRs have multiple links in between and you want to establish an LDP session on each link, make sure that all the links use the same transport address.
Page 59: Reset Mpls Ldp
If it is not, the LSR adds its own LSR ID into the message. • • If it is, the LSR considers that a loop occurs and terminates LSP establishment. In addition, when the number of LSR IDs in the message reaches the path vector limit, LDP also considers that a loop occurs and terminates LSP establishment.

Usage guidelines When you redistribute OSPF routes into BGP, BGP does the following: Adds the configured OSPF domain ID to the redistributed BGP VPN routes as a BGP extended • community attribute. • Advertises the routes to the BGP peer. When you redistribute the BGP VPN routes into OSPF on the BGP peer, OSPF uses the domain ID to determine whether the routes belong to the same OSPF routing domain.

Usage guidelines The reserved VLAN of a VPN instance provides resources for the VPN instance to complete packet forwarding. A common VLAN (for example, a default VLAN, a VLAN created by using the vlan command, and a dynamically learned VLAN) cannot be specified as a reserved VLAN. After you specify a VLAN as the reserved VLAN of a VPN instance, the VLAN cannot be created by using the vlan command or be dynamically learned.

Page 96: Route-Tag
PE ignores the LSA in route calculation to avoid routing loops. HP recommends that you configure the same external route tag for PEs in the same area. An external route tag is not transferred in any BGP extended community attribute. It is only locally significant and takes effect only on the PEs that receive BGP routes and generate OSPF Type 5 or 7 LSAs.
Page 97: Routing-Table Limit

A tunnel policy specified in IPv4 VPN view or IPv6 VPN view is applicable to only the IPv4 VPN or IPv6 VPN. IPv4/IPv6 VPN prefers the tunnel policy specified in IPv4/IPv6 VPN view over the tunnel policy specified in VPN instance view. Examples # Associate VPN instance vpn1 with tunnel policy po1.

Usage guidelines The periodic MPLS traceroute function automatically traces an LSP tunnel at a specific interval. It locates errors on the LSP tunnel, verifies the consistency of the data plane and control plane, and records the detected errors into system logs. You can check the logs to monitor LSP connectivity. If both BFD and periodic MPLS traceroute are configured for an LSP and the periodic traceroute function detects a data plane and control plane inconsistency, the device deletes the BFD session for the LSP and reestablishes the BFD session based on the control plane.
Page 148 -rtos tos-value: Specifies the ToS value in the IP header of an MPLS echo reply packet. The value range is 0 to 7, and the default value is 6. -s packet-size: Specifies the length (excluding the IP header and UDP header) of an MPLS echo request packet.
