Parameters

None

Description

Use the mpls rsvp-te command to enable RSVP-TE.

Use the undo mpls rsvp-te command 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, you need to enable MPLS in system view and MPLS TE in MPLS view.

· Before enabling RSVP-TE in interface view, you need to enable MPLS and MPLS TE in interface view.

· Disabling RSVP-TE in MPLS view disables RSVP-TE on interfaces.

Default level

2: System level

Parameters

cipher: Enters and displays the authentication key in cipher text.

plain: Enters the authentication key in plain text and displays the authentication key in plain text.

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

Description

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

Use the undo mpls rsvp-te authentication command 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 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.

Examples

# Enable RSVP authentication on interface GigabitEthernet 3/1/1, and configure the authentication key as userkey1 in plain text.

mpls rsvp-te blockade-multiplier

Syntax

mpls rsvp-te blockade-multiplier number

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

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

The default blockade multiplier is 4.

Sometimes, although a reservation request does not pass admission control on some node, you may 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.

Before you can configure this command, enable RSVP-TE.

Related commands: mpls rsvp-te timer refresh.

Examples

# Set the blockade multiplier to 5.

Parameters

None

Description

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

Use the undo mpls rsvp-te hello command 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.

Default level

2: System level

Parameters

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

Description

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

Use the undo mpls rsvp-te hello-lost command 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.

Related commands: mpls rsvp-te timer hello.

Parameters

increment-value increment-value: Increment value delta, in the range of 1 to 10. The default is 1.

retransmit-value retrans-timer-value: Initial retransmission interval, in the range of 500 to 3000 milliseconds. The default is 500 milliseconds.

Description

Use the mpls rsvp-te timer retransmission command to enable RSVP message retransmission.

Use the undo mpls rsvp-te timer retransmission command 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 in the mpls rsvp-te timer retransmission command, and the delta value is specified by increment-value in this command.

Parameters

bandwidth: Total bandwidth that the bypass tunnel can protect, in the range of 1 to 32000000 kbps.

ct0: Indicates that only the LSPs of CT 0 can use the bypass tunnel.

ct1: Indicates that only the LSPs of CT 1 can use the bypass tunnel.

ct2: Indicates that only the LSPs of CT 2 can use the bypass tunnel.

ct3: Indicates that only the LSPs of CT 3 can use the bypass tunnel.

un-limited: Puts on limit on total protected bandwidth.

Description

Use the mpls te backup bandwidth command to configure the total bandwidth and type of LSP that the bypass tunnel can protect.

Use the undo mpls te backup bandwidth command to remove the configuration.

By default, bypass tunnels do not protect bandwidth.

When you use the command, follow these guidelines:

· If no CT is specified, all LSPs can use the bypass tunnel.

· The bandwidth value specified with this command is used for only calculating and determining the bandwidth protection relationship. No bandwidth will be reserved in the bypass tunnel.

· The specified bandwidth value must be less than the actual bandwidth of the bypass tunnel. Otherwise, the bypass tunnel may be overwhelmed after FRR switchover, causing the protected tunnel to be torn down.

NOTE:

This command is not supported when the signaling protocol is CR-LDP.

Examples

# Configure Tunnel 3 to provide protection for LSPs of CT 0 without constraining the bandwidth to be protected. Configure Tunnel 2 to provide protection for LSPs of CT 1 and protect up to 1000 kbps bandwidth.

By default, the bandwidth assigned to an MPLS TE tunnel is 0 and the tunnel’s traffic belongs to CT 0.

If no CT is specified, the tunnel’s traffic belongs to CT 0.

NOTE:

· On the SR8800 routers, if there are multiple data streams in an MPLS TE tunnel, each data stream corresponds to one outgoing interface of the tunnel.

· If an MPLS TE tunnel has multiple outgoing interfaces (for example, when the egress of the tunnel is an aggregation group with multiple interfaces), the mpls te bandwidth command takes effect on all the interfaces. In this case, if there are multiple data streams in the tunnel, the actual bandwidth is the product of the configured bandwidth of the tunnel and the number of outgoing interfaces servicing data streams.

· If an MPLS TE tunnel needs a bandwidth greater than 1024 kbps, H3C recommends setting the bandwidth value to a multiple of 1024 kbps.

Examples

# Assign 1000 kbps bandwidth to MPLS TE tunnel 3 and specify the CT of the tunnel’s traffic as CT 1.

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.

You need to enable LSP verification by using the mpls lspv command before executing the mpls te periodic-tracert command.

undo mpls te priority

View

Tunnel interface view

Default level

2: System level

Parameters

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

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

Description

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

Use the undo mpls te priority command 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.

Syntax

mpls te protection tunnel tunnel-id [ holdoff holdoff-time ] [ mode { non-revertive | revertive [ wtr wtr-time ] } ]

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 router 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 router will switch data to the protection tunnel. The holdoff-time is the holdoff time factor, which ranges from 0 to 20 and defaults 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, that is, 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, that is, 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, that is, 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 the mpls te protection tunnel command to configure a protection tunnel for the main tunnel.

Use the undo mpls te protection tunnel command 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, you need to 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.

Parameters

Interval: Interval for advertising bandwidth, in the range of 0 to 3600, in seconds.

Description

Use the mpls te timer link-management periodic-flooding command to configure the interval for advertising updated bandwidth.

Use the undo mpls te timer link-management periodic-flooding command to restore the default.

By default, the bandwidth advertisement interval is 180 seconds.

The interval specified by this command is that at which the system will periodically advertise interface bandwidth if the bandwidth changes are within the specified threshold. Setting the interval to 0 means to disable the bandwidth advertisement function. The minimal valid interval is 30 seconds, that is, if you set the interval to a value less than 30, the system will take 30 seconds as the interval. If you change the interval before the current interval elapses, the new setting will take effect. For example, if you set the interval to 30 seconds, and then, within 30 seconds, set the interval to 3600 seconds, the interval of 3600 seconds will take effect.

tunnel-name: Tunnel name, a case-sensitive string of 1 to 15 characters.

incoming-interface interface-type interface-number: Specifies an incoming interface for the static CR-LSP.

in-label in-label-value: Specifies the incoming label, which ranges from 16 to 1023.

nexthop next-hop-addr: Specifies the next hop address.

outgoing-interface interface-type interface-number: Specifies an outgoing interface for the static CR-LSP.

out-label out-label-value: Specifies the outgoing label, which can be a value of 0, 3, 16 through 1023.

bandwidth: Specifies the class type (CT) for static CR-LSP traffic. By default, static CR-LSP traffic belongs to CT 0.

ct0: Specifies CT 0 for static CR-LSP traffic.

ct1: Specifies CT 1 for static CR-LSP traffic.

ct2: Specifies CT 2 for static CR-LSP traffic.

ct3: Specifies CT 3 for static CR-LSP traffic.

bandwidth-value: Bandwidth assigned to the static CR-LSP, in the range of 1 to 32000000 kbps.

Description

Use the static-cr-lsp transit command to configure a static CR-LSP on a transit node.

Use the undo static-cr-lsp transit command to remove the static CR-LSP.

CT 2 and CT 3 can be used in only IETF DS-TE mode. In prestandard DS-TE mode, the configuration of CT 2 or CT 3 is invalid, and thus the tunnel cannot be established.

NOTE:

The next hop address cannot be a local public address when configuring the static CR-LSP on the ingress or a transit node.

Examples

# Configure a static CR-LSP on the transit node, setting its name to tunnel3, incoming interface to GigabitEthernet 3/1/1, incoming label to 123, outgoing interface to GigabitEthernet 4/1/1, outgoing label to 253, CT of traffic to CT 0, and required bandwidth to 20 kbps.

Default level

2: System level

Parameters

bw-constraint value: Sets the bandwidth constraint sub-TLV. value is the sub-TLV value in the range of 19 to 254.

lo-multiplier value: Sets the sub-TLV of local overbooking multiplier (LOM). value is the sub-TLV value in the range of 19 to 254.

unreserved-bw-sub-pool value: Sets the sub-TLV of unreserved subpool bandwidth. value is the sub-TLV value in the range of 19 to 254.

Description

Use the te-set-subtlv command to configure the sub-TLVs carrying the DS-TE parameters. As no standard is available for these sub-TLVs, you need to configure them manually for interoperability with other vendors' routers.

Use the undo te-set-subtlv command to restore the default.

By default, the bandwidth constraint sub-TLV is 252, the sub-TLV of LOM is 253, and the sub-TLV of unreserved subpool bandwidth is 251.

2: System level

Parameters

level-1: Enables Level-1 IS-IS TE.

level-1-2: Enables Level-1-2 IS-IS TE.

level-2: Enables Level-2 IS-IS TE.

NOTE:

If no level is specified, IS-IS TE applies to Level-1-2.

Description

Use the traffic-eng command to enable IS-IS TE.

Use the undo traffic-eng command to restore the default.

By default, IS-IS TE is disabled.

NOTE:

In order to enable IS-IS TE, you must use the cost-style command to configure the cost style of the IS-IS packet to wide, compatible or wide-compatible. For more information about the cost-style command, see Layer 3—IP Routing Command Reference.
