segment-routing ipv6 locator (BGP-VPN instance IPv4 address family view)

Function

The segment-routing ipv6 locator command enables a device to add SIDs into private network routes.

The undo segment-routing ipv6 locator command disables a device from adding SIDs into private network routes.

By default, the private network routes do not have SIDs.

Format

segment-routing ipv6 locator locator-name [ auto-sid-disable ]

undo segment-routing ipv6 locator [ [ locator-name ] | [ locator-name auto-sid-disable ] ]

Parameters

Parameter	Description	Value
locator-name	Specifies the name of a SID node route locator, which was configured through the locator command.	The value is a string of 1 to 31 case-sensitive characters. When double quotation marks are used around the string, spaces are allowed in the string.
auto-sid-disable	Specifies to disable the dynamic SID allocation function. If the auto-sid-disable parameter is not configured, SIDs can be dynamically assigned. If static SIDs configured by the opcode command exist in locator-name, the static SIDs are used. If no static SIDs exist, dynamically assigned SIDs are used.	-

Parameter

Description

Value

locator-name

Specifies the name of a SID node route locator, which was configured through the locator command.

The value is a string of 1 to 31 case-sensitive characters. When double quotation marks are used around the string, spaces are allowed in the string.

auto-sid-disable

Specifies to disable the dynamic SID allocation function.

If the auto-sid-disable parameter is not configured, SIDs can be dynamically assigned. If static SIDs configured by the opcode command exist in locator-name, the static SIDs are used. If no static SIDs exist, dynamically assigned SIDs are used.

Usage Guidelines

Usage Scenario

In SRv6 VPN, private network route information of VPN instance is transferred using BGP. By default, the private network routes do not have SIDs, the segment-routing ipv6 locator command enables a device to add SIDs in private network routes.

After the BGP VPNv4 neighbor is set up and the peer ipv6-address prefix-sid command is enabled, the BGP peers can exchange the private network routing information carrying the SID attributes through the BGP VPNv4 neighbor.

Precautions

The configuration fails if the operation code-specific END.DT4 VPN of the locator does not match the private network VPN instance or the specified locator does not exist.

Example

# Enable a device to send private network routes that carry SIDs, and enable the SID dynamic allocation capability.
