Parameters

None

Description

Use mpls rsvp-te to enable RSVP-TE.

Use undo mpls rsvp-te to disable RSVP-TE.

By default, RSVP-TE is disabled.

You must enable RSVP-TE before you can configure other RSVP-TE features.

Before enabling RSVP-TE in MPLS view on a node, enable MPLS in system view and MPLS TE in MPLS view.

Before enabling RSVP-TE in interface view, enable MPLS and MPLS TE in interface view.

Parameters

cipher: Specifies a ciphertext key. This key will be displayed in cipher text.

plain: Specifies a plaintext key. This key will be displayed in cipher text.

auth-key: Specifies the key string. This argument is case sensitive. If the cipher keyword is specified, it must be a ciphertext string of 8 to 53 characters. If the plain keyword is specified, it is a plaintext string of 8 to 16 characters.

Description

Use mpls rsvp-te authentication to enable RSVP authentication on the interface.

Use undo mpls rsvp-te authentication to disable RSVP authentication on the interface.

By default, RSVP authentication is disabled.

The RSVP messages sent out of the interface convey a message authentication digest created using the hash algorithm and the configured authentication key. This authentication key is also used by the interface to authenticate received RSVP messages. For the two interfaces at the two ends of a link to exchange RSVP messages, they must share the same authentication key.

This hop-by-hop authentication of RSVP prevents fake resource reservation requests from occupying network resources.

undo mpls rsvp-te blockade-multiplier

View

MPLS view

Default level

2: System level

Parameters

number: Blockade multiplier in the range of 3 to 255.

Description

Use mpls rsvp-te blockade-multiplier to configure the blockade multiplier, which determines the timeout time of blockade state.

Use undo mpls rsvp-te blockade-multiplier to restore the default.

The default blockade multiplier is 4.

Sometimes, although a reservation request does not pass admission control on some node, you might want to store the resource reservation state for it while allowing other requests to use the resources reserved for the request. In this case, the node transits to the blockade state and a blockade state block (BSB) is created on each downstream node. When the number of non-refreshing times exceeds the blockade multiplier, the blockade state is removed. The blockade state timeout time is blockade multiplier × refresh-time. The refresh time is the refresh interval of the path/reservation messages.

Enable RSVP-TE before configuring this command.

Related commands: mpls rsvp-te timer refresh.

Examples

# Set the blockade multiplier to 5.

Parameters

None

Description

Use mpls rsvp-te hello to enable RSVP hello extension.

Use undo mpls rsvp-te hello to disable RSVP hello extension.

By default, RSVP hello extension is disabled.

RSVP-TE uses the hello extension mechanism to check the reachability of an RSVP neighbor.

Parameters

times: Maximum number of consecutive hello losses before an RSVP neighbor is considered dead, in the range of 3 to 10.

Description

Use mpls rsvp-te hello-lost to configure the maximum number of consecutive hello losses before an RSVP neighbor is considered dead.

Use undo mpls rsvp-te hello-lost to restore the default.

By default, the RSVP node considers an RSVP neighbor to be dead if no response is received after sending three consecutive hellos.

An RSVP node detects whether its RSVP neighbor is still alive by sending hellos regularly. If no response is received after the number of consecutive hellos reaches the specified limit, the RSVP node considers its RSVP neighbor as dead. The failure is handled the same as a link layer communication failure.

Before configuring this command, enable RSVP-TE and RSVP hello extension in MPLS view.

Use undo mpls rsvp-te timer retransmission to restore the default.

By default, RSVP message retransmission is disabled.

If a node sends a message carrying the Message_ID object, and the ACK_Desired flag in the object is set, the node expects a response that carries the Message_ID_ACK object during the initial retransmission interval (Rf). If the node does not receive the response within the Rf interval, it resends the message and sets the retransmission interval to (1+Delta) × Rf. The node repeats such retransmissions until it receives the corresponding response within the retransmission time or the number of retransmission attempts reaches the limit.

The initial value of the retransmission time is specified by retrans-timer-value, and the delta value is specified by increment-value in this command.

Parameters

None

Description

Use mpls te cspf to enable CSPF.

Use undo mpls te cspf to disable CSPF.

By default, CSPF is disabled.

Before enabling CSPF, enable MPLS TE in MPLS view.

CSPF provides a method to path selection in MPLS domains. You must enable CSPF to establish an MPLS TE tunnel through dynamic signaling.

You must enable CSPF before configuring other CSPF related functions.

Parameters

timer-interval: Value of the failed link timer, in the range of 0 to 300 seconds. The default is 10 seconds.

Description

Use mpls te cspf timer failed-link to configure the failed link timer.

Use undo mpls te cspf timer failed-link to restore the default.

By default, the failed link timer is 10 seconds.

The failed link timer starts once a link goes down. If the IGP removes or modifies the link before the timer expires, CSPF updates information about the link in TEDB and stops the timer. If the IGP does not remove or modify the link before the timer expires, the state of the link in TEDB will change to up.

Related commands: mpls te cspf.

Parameters

-a source-ip: Specifies the source IP address of MPLS Echo Request messages. By default, the MPLS LSR ID is used as the source address of MPLS Echo Request messages.

-exp exp-value: Specifies the EXP value of the label. exp-value is in the range of 0 to 7 and defaults to 0.

-h ttl-value: Specifies the TTL value to be carried by an MPLS Echo Request message. ttl-number is in the range of 1 to 255 and defaults to 30.

-m wait-time: Specifies the interval for performing LSP tracert. wait-time is in the range of 15 to 120 and defaults to 60, in minutes.

-t time-out: Specifies the timeout time for waiting for the response of an MPLS Echo Request message. time-out is in the range of 0 to 65535 and defaults to 2000, in milliseconds.

-u retry-attempt: Specifies the maximum number of times that MPLS Echo Request messages can be sent if no response is received. retry-attempt is in the range of 1 to 9 and defaults to 3.

Description

Use mpls te periodic-tracert to enable periodic LSP tracert for the MPLS TE tunnels on a tunnel interface.

Use undo mpls te periodic-tracert to disable periodic LSP tracert for MPLS TE tunnels on a tunnel interface.

By default, periodic LSP tracert is disabled for MPLS TE tunnels.

The periodic LSP tracert function for an MPLS TE tunnel is for locating faults of the MPLS TE tunnel periodically. It detects the consistency of the forwarding and control plane and records detection results into logs. You can know whether an MPLS TE tunnel has failed by checking the logs.

If you configure BFD as well as periodical tracert for an MPLS TE tunnel, once the tracert function detects a data plane failure or an inconsistency between the data plane and control plane, the existing BFD session is deleted and a new BFD session is then re-established based on the control plane.

Enable LSP verification by using the mpls lspv command before executing the mpls te periodic-tracert command.

2: System level

Parameters

setup-priority: Setup priority of the tunnel, in the range of 0 to 7. A lower numerical number represents a higher priority.

hold-priority: Holding priority of the tunnel, in the range of 0 to 7. A lower numerical number represents a higher priority. If not configured, it is the same as the setup priority.

Description

Use mpls te priority to assign a setup priority and holding priority to the MPLS TE tunnel.

Use undo mpls te priority to restore the default.

By default, both setup and holding priorities of TE tunnels are 7.

To avoid flapping caused by improper preemptions between TE tunnels, the setup priority of an MPLS TE tunnel should not be set higher than its holding priority.

undo mpls te protection tunnel

View

Tunnel interface view

Default level

2: System level

Parameters

tunnel-id: ID of the tunnel to be specified as the protection tunnel.

holdoff holdoff-time: Specifies the switching delay time. After detecting that the main tunnel fails, the switch will not switch data to the protection tunnel immediately but wait for a period of time (the holdoff time). If the protection tunnel keeps in no-defect state during this period of time, the switch will switch data to the protection tunnel. The holdoff-time is the holdoff time factor in the range of 0 to 20, and the default is to 0. Holdoff time = holdoff time factor × 500 milliseconds. Therefore, the maximum holdoff time is 10 seconds.

mode: Specifies the reverting mode, non-revertive or revertive. The default reverting mode is revertive.

non-revertive: Specifies the non-revertive mode, where data will not be switched back from the protection tunnel to the main tunnel even if the main tunnel recovers.

revertive: Specifies the revertive mode, where data will be switched back from the protection tunnel to the main tunnel when the main tunnel recovers.

wtr wtr-time: Specifies the reverting delay time, or, the time to wait before switching back to the main tunnel. wtr-time is the WTR time factor, which is in the range of 0 to 60 and defaults to 24. WTR time = WTR time factor × 30 seconds. Therefore, the default WTR time is 12 minutes.

Description

Use mpls te protection tunnel to configure a protection tunnel for the main tunnel. The main tunnel and its protection tunnel (also called "backup tunnel") form a tunnel protection group.

Use undo mpls te protection tunnel to remove the protection tunnel of a main tunnel.

By default, no protection tunnel is configured for the main tunnel.

Before configuring the mpls te protection tunnel command, execute the tunnel-protocol mpls te command in tunnel interface view.

The configured protection tunnel takes effect only after you execute the mpls te commit command in the tunnel interface view.

Because the bypass tunnel configured in TE FRR cannot be applied in VPN applications, do not configure a protection tunnel for the bypass tunnel of TE FRR.

Tunnel interface view

Default level

2: System level

Parameters

acl acl-number: Configures the MPLS TE tunnel to forward only VPN traffic that matches the specified ACL. The ACL number is in the range of 3000 to 3999.

vpn-instance vpn-instance-name: Configures the MPLS TE tunnel to forward only traffic of the specified VPN. The vpn-instance-name argument specifies an MPLS L3VPN by its instance name, a case-sensitive string of 1 to 31 characters.

Description

Use mpls te vpn-binding to define the traffic to be forwarded along the MPLS TE tunnel. You can specify the tunnel to forward only the VPN traffic that matches the specified ACL or forward only the traffic of the specified VPN.

Use undo mpls te vpn-binding to restore the default.

By default, no restriction is defined about what traffic can travel down a TE tunnel.

The switch selects a TE tunnel for forwarding VPN traffic in this order: the TE tunnel specified with an ACL, the TE tunnel specified with a VPN instance, the TE tunnel with no restriction on traffic to be forwarded. The switch does not perform load sharing over different types of TE tunnels.

next hop

Syntax

next hop ip-address [ include [ loose | strict ] | exclude ]

View

Explicit path view

Default level

2: System level

Parameters

ip-address: Defines a node by its link IP address or router ID in dotted decimal notation. In the strict routing method, this IP address must be a link IP address. In the loose routing method, this IP address can be either a link IP address or a router ID.

include: Includes the specified IP address on the explicit path.

loose: Specifies the node as a loose node, which means that the ip-address and its previous hop can be connected indirectly.

strict: Specifies the node as a strict node, which means that the ip-address and its previous hop must be directly connected.

Description

Use next hop to define a node on the explicit path. By performing this command multiple times, you can define all nodes that the explicit path must traverse in sequence.

· If you specify neither include nor exclude, the include keyword is used by default.

· If you specify neither loose nor strict, the strict keyword is used by default.
