+Segment Routing over IPv6 (SRv6)
+-------------------------
+
+.. cfgcmd:: set protocols isis segment-routing srv6 interface <interface>
+
+  The :ref:`dummy interface<configuration/interfaces/dummy:dummy>` used
+  to install SRv6 SIDs into the Linux data plane. The interface must exist and
+  must be present when configuring IS-IS with
+  SRv6.
+
+.. cfgcmd:: set protocols isis segment-routing srv6 locator <locator>
+  
+  Specifies the SRv6 locator to use for IS-IS. IS-IS automatically allocates
+  prefix and adjacency SIDs, creates local SID entries and advertises them
+  into the IGP domain.
+
+.. cfgcmd:: set protocols isis segment-routing srv6 node-msd max-end-d <0-255>
+
+  The Maximum End D MSD Type specifies the maximum number of SIDs present in an
+  SRH when performing decapsulation. As specified in :rfc:`8986`, the permitted
+  SID types include, but are not limited to, End.DX6, End.DT4, End.DT46, End
+  with USD, and End.X with USD.
+
+  If the advertised value is zero or no value is advertised, then the router
+  cannot apply any behavior that results in decapsulation and forwarding of the
+  inner packet if the outer IPv6 header contains an SRH.
+
+  Reference: :rfc:`9352`
+
+.. cfgcmd:: set protocols isis segment-routing srv6 node-msd max-end-pop <0-255>
+
+  The Maximum End Pop MSD Type signals the maximum number of SIDs in the SRH to
+  which the router can apply "Penultimate Segment Pop (PSP) of the SRH" or
+  "Ultimate Segment Pop (USP) of the SRH" behavior, as defined in "Flavors"
+  (Section 4.16 of :rfc:`8986`).
+
+  If the advertised value is zero or no value is advertised, then the router
+  cannot apply PSP or USP flavors.
+
+  Reference: :rfc:`9352`
+
+.. cfgcmd:: set protocols isis segment-routing srv6 node-msd max-h-encaps <0-255>
+
+  The Maximum H.Encaps MSD Type signals the maximum number of SIDs that can be
+  added to the segment list of an SRH as part of the "H.Encaps" behavior, as
+  defined in :rfc:`8986`.
+
+  If the advertised value is zero or no value is advertised, then the headend
+  can apply an SR Policy that only contains one segment without inserting any
+  SRH header. A non-zero SRH Max H.encaps MSD indicates that the headend can
+  insert an SRH up to the advertised number of SIDs.
+
+  Reference: :rfc:`9352`
+
+.. cfgcmd:: set protocols isis segment-routing srv6 node-msd max-segs-left <0-255>
+
+  The Maximum Segments Left MSD Type signals the maximum value of the
+  "Segments Left" field (:rfc:`8754`) in the SRH of a received packet before
+  applying the Endpoint behavior associated with a SID.
+
+  If no value is advertised, the supported value is 0.

+  Reference: :rfc:`9352`
