Function

The display segment-routing seamless-bfd tunnel session command displays SBFD session information about Segment Routing tunnels.

Format

display segment-routing seamless-bfd tunnel session [ prefix ip-address { mask | mask-length } ] [ flex-algo [ flexAlgoId ] ]

Parameters

Parameter	Description	Value
prefix ip-address	Displays SBFD information about the Segment Routing tunnel with a specified prefix.	The value is in dotted decimal notation.
mask	Specifies the IP address mask.	The value is in dotted decimal notation.
mask-length	Specifies the length of the IP address mask.	The value is an integer ranging from 0 to 32.
flex-algo flexAlgoId	Specifies a flexible algorithm identifier.	The value is an integer ranging from 128 to 255.

Usage Guidelines

Usage Scenario

After SBFD is configured to monitor a Segment Routing tunnel, run the display segment-routing seamless-bfd tunnel session command to view information about the SBFD session.

If the prefix ip-address parameter is configured, information about an SBFD session monitoring a Segment Routing tunnel with a specified destination IP address is displayed. If this parameter is not configured, information about all SBFD sessions that monitor Segment Routing tunnels is displayed.

Example

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