Parameters

locator-name: Specifies a locator by its name, a case-sensitive string of 1 to 31 characters.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. Only routes that match the routing policy can be generated in the BGP IPv6 unicast routing table for the locator. All routes for the locator can be generated in the BGP IPv6 unicast routing table in the following situations:

· You do not specify a routing policy when using this command.

· The specified routing policy does not exist.

· The specified routing policy does not contain if-match clauses.

Usage guidelines

Use this command in an inter-AS BGP network. This command enables the device to use BGP to advertise routes for a locator.

Repeat this command to enable the device to use BGP to advertise routes for multiple locators.

Examples

# Enable the device to generate routes for locator abc in the BGP IPv6 unicast routing table and advertise the routes to BGP peers.

Usage guidelines

After you apply a locator to a routing protocol, the routing protocol will advertise the SRv6 SIDs in the locator. By default, the N-bit is set in the Flags field of the Locator TLV in routing protocol packets. The locator belongs to one SRv6 node. If you enable anycast for a locator, the A-bit is set in the Flags field of the Locator TLV in routing protocol packets. The locator is shared by a group of SRv6 nodes.

Examples

# Enable anycast for locator test1.

<Sysname> system-view

[Sysname] segment-routing ipv6

[Sysname-segment-routing-ipv6] locator test1 ipv6-prefix 100:: 64 static 32

Parameters

locator-name: Specifies a locator name, a case-sensitive string of 1 to 31 characters.

ipv6-prefix ipv6-address prefix-length: Specifies an IPv6 address prefix and the prefix length, which represent the value and length for the locator in SRv6 SIDs, respectively. The ipv6-address argument represents the IPv6 address prefix. The prefix-length argument represents the prefix length, in the range of 32 to 120. The IPv6 address prefix cannot be an IPv4-compatible IPv6 address.

args args-length: Specifies an argument length. The value range for the args-length argument depends on the value of the prefix-length argument and varies by device model. If you do not specify an argument length, the argument length is 0.

static static-length: Specifies the static length. The value range for the static-length argument varies by the value of the prefix-length argument and varies by device model. If you do not specify a static length, the static length is 0.

Usage guidelines

The locator command is used not only for configuring the value and length for the locator in SRv6 SIDs but also for planning the length of the Function, Arguments, and MBZ fields. All SRv6 SIDs are allocated by the locator command. According to whether compression is supported, configure the parameters differently for SRv6 SIDs. For more information, see SRv6 in Segment Routing Configuration Guide.

If a static opcode has been configured, a routing protocol preferentially uses the static opcode to construct SRv6 SIDs. If no static opcode exists, the routing protocol dynamically allocates SRv6 SIDs.

By applying a locator to IGP and BGP, you can use IGP and BGP to advertise the SRv6 SIDs on the locator.

When you create a locator, you must specify an IPv6 address prefix, prefix length, and static length for the locator. When you enter the view of an existing SRv6 locator, you do not need to specify the IPv6 address prefix, prefix length, or static length of the locator.

Each locator must have a unique name.

Do not specify the same IPv6 address prefix and prefix length for different locators. In addition, the IPv6 address prefixes of different locators cannot overlap.

You cannot delete a locator if that locator has dynamic SRv6 SIDs that are being used.

Examples

# Configure locator test1, setting the IPv6 address prefix to 100::, prefix length to 64, and static length to 32, and enter the SRv6 locator view of this locator.

<Sysname> system-view

Parameters

opcode: Specifies an opcode. The value range varies by the settings of the locator command.

hex hex-opcode: Specifies an SRv6 SID in hexadecimal notation. The hex-opcode argument represents the SRv6 SID in hexadecimal notation.

end-dt4: Specifies the End.DT4 type.

end-dt46: Specifies the End.DT46 type.

end-dt6: Specifies the End.DT6 type.

end-dx4: Specifies the End.DX4 type.

interface interface-type interface-number: Specifies an output interface.

nexthop nexthop-ipv4-address: Specifies a next hop IPv4 address.

nexthop nexthop-ipv6-address: Specifies a next hop IPv6 address.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the SRv6 SIDs belong. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The specified VPN instance must exist. If the SRv6 SIDs belong to the public network, do not specify this option.

evpn: Specifies EVPN routes. If you do not specify this keyword, the command specifies the SRv6 SIDs of VPNv4 or VPNv6 routes.

l3vpn-evpn: Specifies EVPN routes, VPNv4 routes, and VPNv6 routes.

Usage guidelines

An SRv6 locator and its opcode and argument generate unique SRv6 SIDs. SRv6 SIDs form local SID forwarding table entries.

Use this command to configure the opcode of static SRv6 SIDs on a locator. The number of static SRv6 SIDs is determined by the static static-length option in the locator command.

If you specify the hex keyword in this command, and the length of the static portion in the locator to which the SID belongs is 32, you can use the IPv4 address format to specify the value of the SID, for example, opcode hex ::1.2.3.4 end no-flavor. The configured opcode value is displayed in hexadecimal format.

To modify the opcode of static SRv6 SIDs on a locator, you must first delete the original opcode by using the undo opcode command.

Examples

# Configure End.DT4 SRv6 SIDs, and set the opcode to 1.2.3.4.

<Sysname> system-view

[Sysname] segment-routing ipv6

[Sysname-segment-routing-ipv6] locator test ipv6-prefix 100:: 64 static 32

Parameters

tag-value: Specifies an administrative tag value, in the range of 1 to 4294967295.

Usage guidelines

Application scenarios

To import only specific SRv6 locators when the device imports IS-IS routes from different levels and areas or learns IS-IS routes from IS-IS neighbors, use this command to configure the administrative tag value for SRv6 locators. Then use the if-match tag command to filter SRv6 locators with different administrative tags.

Operating mechanism

With this feature configured, IS-IS will carry a 32-bit administrative tag sub-TLV with type 1 and value tag-value in the SRv6 locator TLV with type 27 when it advertises an SRv6 locator. This SRv6 locator is then marked through the administrative tag Sub-TLV.

Restrictions and guidelines

You can use this command to configure the same administrative tag value for all SRv6 locators advertised by IS-IS. Alternatively, you can use the segment-routing ipv6 locator command with the tag keyword specified in IS-IS IPv6 address family view to configure different administrative tag values for different SR6 locators.

For the same SRv6 locator, the administrative tag value specified using the segment-routing ipv6 locator command in IS-IS IPv6 address family view takes precedence. If no administrative tag value is specified using this command, the administrative tag value specified using the segment-routing ipv6 admin-tag command is applied.

This command is available only if the link cost style is wide, wide-compatible, or compatible.

Examples

# Configure administrative tag value 100 for SRv6 locators on IS-IS process 1.

Usage guidelines

Application scenarios

To avoid interoperability issues caused by differences in the Locator field length in the SRv6 Locator TLV when a third-party device or an H3C device with an older software version interoperates with an H3C device with a newer software version, you can this command to have the new devices compatible with older draft standards.

Operating mechanism

In the OSPFv3 protocol, the SRv6 Locator TLV is carried in the SRv6 Locator LSA, used to announce the network segment and mask of the locator to which the SRv6 SID belongs, as well as the End SID related to that locator.

The length of the Locator field in SRv6 Locator TLVs is defined as variable in draft-ietf-lsr-ospfv3-srv6-extensions-12 and later drafts and can be up to 128 bits. The length of the Locator field can vary based on the configured locator segment length. However, the length is fixed at 128 bits in draft-ietf-lsr-ospfv3-srv6-extensions-11 and earlier drafts. For example, if you specify the prefix-length argument as 96 in the locator command, the default Locator field length is 96 bits and the remaining 32 bits are not required in the TLV when you apply the locator to OSPFv3 and advertise it. After this command is configured, the Locator field must be 128-bit long and the remaining 32 bits are all set to zero.

Restrictions and guidelines

For compatibility with draft-ietf-lsr-ospfv3-srv6-extensions-08 and earlier drafts, you must both this command and the segment-routing ipv6 private-srv6-extensions compatible command.

Parameters

locator-name: Specifies a locator by its name, a case-sensitive string of 1 to 31 characters.

level-1: Specifies the level-1 area.

level-2: Specifies the level-2 area.

auto-sid-disable: Disables automatic SRv6 SID allocation. If you do not specify this keyword, the device allows dynamically allocated SRv6 SIDs. If static SRv6 SIDs are configured when automatic SRv6 SID allocation is enabled, the static SRv6 SIDs take precedence. If no static SRv6 SIDs are configured when automatic SRv6 SID allocation is enabled, the system dynamically allocates SRv6 SIDs.

cost cost-value: Specifies a cost value for locators, in the range of 1 to 16777215.

tag tag-value: Specifies an administrative tag value, in the range of 1 to 4294967295.

Usage guidelines

Application scenarios

For IS-IS neighbors in an IS-IS network to access each other through SRv6 SIDs, configure this feature.

Operating mechanism

With this command configured, IS-IS can advertise the specified locator and the SRv6 SIDs in the locator. After learning the locator and the SRv6 SIDs in the locator, the IS-IS neighbors generate route entries.

When multiple nodes use IS-IS to reference and advertise the same SRv6 locator, you can specify different cost values for the same SRv6 locator on different nodes for optimal route selection.

Restrictions and guidelines

If you do not specify a level, this command applies the specified locator to both level-1 and level-2 areas.

Use this command only when the cost style of IS-IS is wide, compatible, or wide-compatible.

Execute this command multiple times to apply multiple locators to an IPv6 IS-IS process so that the process can advertise multiple SRv6 SIDs.

You can use this command with the tag keyword specified to configure different administrative tag values for different SR6 locators. Alternatively, you can use the segment-routing ipv6 admin-tag command to configure the same administrative tag value for all SRv6 locators advertised by IS-IS.
