igp shortcut isis (SRv6 flow group view)

Function

The igp shortcut isis command enables an SRv6 TE flow group to support IGP route advertisement through the shortcut function.

The undo igp shortcut isis command disables an SRv6 TE flow group from supporting IGP route advertisement through the shortcut function.

By default, an SRv6 TE flow group does not support IGP route advertisement through the shortcut function.

Format

igp shortcut isis [ route-policy route-policy-name ]

undo igp shortcut isis [ route-policy route-policy-name ]

Parameters

Parameter	Description	Value
route-policy route-policy-name	Specifies the name of a route-policy used to filter routes.	The value is a string of 1 to 200 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. If a route-policy is configured and path computation is complete, selective route recursion can be performed based on the route-policy. If no route-policy is configured, only the recursion of 128-bit host routes is supported by default.
