display segment-routing state ip-prefix
Function
The display segment-routing state ip-prefix command displays Segment Routing status information based on a specified address prefix.
Parameters
| Parameter | Description | Value |
|---|---|---|
| ip-prefix |
Specifies an IP address prefix. |
The value is in dotted decimal notation. |
| mask-length |
Specifies a mask length. |
The value is an integer ranging from 0 to 32. |
| flex-algo flexAlgoId |
Specifies the flexible algorithm identifier. |
The value is an integer ranging from 128 to 255. |
Usage Guidelines
Usage Scenario
To view Segment Routing status information based on a specified address prefix, run the display segment-routing state ip-prefix command. The command output helps query the status of key elements used in the establishment of a Segment Routing tunnel based on the specified prefix and mask.

The actual command output varies according to the device. The command output here is only an example.

| Item | Description |
|---|---|
| Protocol | Protocol. |
| Process ID | Process ID. |
| Prefix-SID | Prefix SID. This is the preferentially selected prefix SID in a process mapped to a specified prefix. If the same prefix and different SIDs are set on different nodes, a process preferentially selects an active SID based on a specified rule. |
| Prefix-SID within min SRGB range | Whether a prefix SID is within the smallest SRGB scope. The smallest SRGB scope is determined among all SRGB scopes on all nodes on a whole path including the root node. |
| Prefix-SID favor state | Whether the prefix SID is preferred. If the same prefix and different SIDs are set on different nodes, a process preferentially selects an active SID based on a specified rule. |
| Route active state | Whether a route is active. If a service component does not obtain the status, NA is displayed, for example, when a prefix SID that NE-B sends to NE-A is out of the local SRGB scope of NE-A. |
| Eligible within process | Whether a SID is preferentially selected within a process.
|
| Eligible between processes or protocols | Whether the Segment Routing next hop is preferentially selected within a process or between protocols. NA indicates that the SEGR does not receive Segment Routing information. The possible cause can be inactive routes or a failure to compute a Segment Routing next hop. |
| SR nexthop exist | Whether a Segment Routing next hop exists. |
| Flex-Algo | Flexible Algorithm ID. |
