The end-bier locator command configures a static End.BIER SID for a BFR in BIERv6 sub-domain.
The undo end-bier locator command deletes the static End.BIER SID.
By default, no static End.BIER SID is configured.
| Parameter | Description | Value |
|---|---|---|
| locator-name |
Specifies the name of a SID node route locator. |
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. |
| sid ipv6-sid |
Specifies a static End.BIER SID. The value is in the static SID range configured for the locator in the segment routing IPv6 view. |
The value is a 32-bit hexadecimal number in the format of X:X::X:X. |
| locator |
Specifies a SRv6 locator. |
The value is a string of 1 to 31 characters. |
Usage Scenario
This command applies to BIERv6 networks. Configuring an End.BIER SID helps guide BIERv6 packet forwarding.
The End.BIER SID can be flooded to other BFRs through BFR-prefix reachability information. When forwarding a BIERv6 packet, the device uses the End.BIER SID of the next hop as the destination address in the IPv6 packet header. When the next hop receives the IPv6 packet, it forwards the packet as a BIERv6 packet after it finds that the destination address in the IPv6 header is the local End.BIER SID.Prerequisites
A BIERv6 sub-domain has been configured using the sub-domain command.
Precautions
If the End.BIER SID conflicts with the remote route address, multicast traffic cannot be forwarded. Therefore, plan End.BIER SIDs properly.
