network-operator

Parameters

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

from begin-value: Specifies available static SRv6 SIDs that start from the specified value. The begin-value argument represents the start value in IPv6 address format. If you do not specify a start value, this command displays available static SRv6 SIDs starting from the smallest available one.

Usage guidelines

If you specify a static length when configuring an SRv6 locator, the device can allocate static SRv6 SIDs from the locator. Use this command to display a maximum of 10 available static SRv6 SIDs in the locator.

To specify the from begin-value option, you must first identify the static SID range of the locator. For this purpose, use the display segment-routing ipv6 locator command.

Use encapsulation source-address to specify a source address for the outer IPv6 header of SRv6 packets.

Use undo encapsulation source-address to restore the default.

Syntax

undo encapsulation source-address

Default

No source address is specified for the outer IPv6 header of SRv6 packets.

Views

Predefined user roles

network-admin

Parameters

ipv6-address: Specifies a source IPv6 address. The IPv6 address cannot be a loopback address, 0:0:0:0:0:0:0:0 or ::, link-local address, multicast address, or unspecified address.

ip-ttl ttl-value: Specifies the TTL of the outer IPv6 header, in the range of 1 to 255. The default value is 255.

Usage guidelines

As a best practice to ensure correct traffic forwarding in an SRv6 network, specify a source address for the outer IPv6 header of SRv6 packets.

You must specify an IPv6 address of the local device as the source IPv6 address, and make sure the IPv6 address has been advertised by a routing protocol. As a best practice, specify a loopback interface address of the local device as the source IPv6 address.

Examples

# Specify 1::1 as the source address of SRv6 packets in the outer IPv6 header and set the TTL of the outer IPv6 header to 200.

<Sysname> system-view

[Sysname] segment-routing ipv6

[Sysname-segment-routing-ipv6] encapsulation source-address 1::1 ip-ttl 200

locator

Use locator to create an SRv6 locator and enter its view, or enter the view of an existing SRv6 locator.

Use undo locator to delete an SRv6 locator.

Syntax

locator locator-name [ ipv6-prefix ipv6-address prefix-length [ args args-length | static static-length ] * ]

undo locator locator-name

Default

No SRv6 locators exist.

Views

SRv6 view

Predefined user roles

network-admin

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. The ipv6-address argument represents the IPv6 address prefix. The prefix-length argument represents the prefix length, in the range of 32 to 120.

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

An SRv6 locator can be different types. For more information about the SRv6 SID fields, see SRv6 configuration 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

[Sysname] segment-routing ipv6

Parameters

opcode: Specifies an opcode in the range of 1 to 2static-length-1, in which the static-length argument is configured by using the locator command.

end-dt4: Specifies the End.DT4 type.

end-dt6: Specifies the End.DT6 type.

end-dt2m: Specifies the End.DT2M type.

end-dt2u: Specifies the End.DT2U type.

weight weight-value: Specifies the load sharing weight value for the path, in the range of 1 to 254. The default value is 1.

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.

vsi vsi-name: Specifies the VSI to which the SRv6 SIDs belong. The vsi-name argument represents the VSI name, a case-sensitive string of 1 to 31 characters. The specified VSI must exist.

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.

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 64.

<Sysname> system-view

[Sysname] segment-routing ipv6

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

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.

Usage guidelines

Use this command to enable IPv6 IS-IS to advertise SRv6 SIDs.

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.

The auto-sid-coc32 keyword takes effect only when the specified locator is a COC32 locator.

The auto-sid-coc-both { all | coc32 | coc32-all | coc32-none } keyword takes effect only when the specified locator is a COC-both locator.

Examples

# Apply locator abc to an IPv6 IS-IS process.

<Sysname> system-view

[Sysname] isis 1

[Sysname-isis-1] cost-style wide

[Sysname-isis-1] address-family ipv6

[Sysname-isis-1-ipv6] segment-routing ipv6 locator abc
