segment-routing ipv6 locator (BGP view/BGP-IPv4 unicast address family view)

Function

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

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

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

Format

segment-routing ipv6 locator locator-name

undo segment-routing ipv6 locator [ locator-name ]

Usage Guidelines

Usage Scenario

By default, public IPv4 unicast routes do not have SIDs, the segment-routing ipv6 locator command enables a device to add SIDs in public network routes.

After the BGP IPv6 neighbor is set up and the peer ipv6-address prefix-sid command is enabled in the IPv4 address family unicast view, the BGP peers can exchange the public network routing information carrying the SID attributes through the BGP IPv6 neighbor.

Prerequisites

The locator command has been run to define a SID node route locator.

Example

# Enable a device to send ipv4 public network routes that carry SIDs.
