+###############
+Segment Routing
+###############
+
+Segment Routing (SR) is a network architecture that is similar to
+source-routing.In this architecture, the ingress router adds a list of segments,
+known as SIDs, to the packet as it enters the network. These segments represent
+different portions of the network path that the packet will take.
+
+The SR segments are portions of the network path taken by the packet, and are
+called SIDs. At each node, the first SID of the list is read, executed as a
+forwarding function, and may be popped to let the next node read the next SID of
+the list. The SID list completely determines the path where the packet is
+forwarded.
+
+Segment Routing can be applied to an existing MPLS-based data plane and defines
+a control plane network architecture. In MPLS networks, segments are encoded as
+MPLS labels and are added at the ingress router. These MPLS labels are then
+exchanged and populated by Interior Gateway Protocols (IGPs) like IS-IS or OSPF
+which are running on most ISPs.
+
+
+.. note:: Segment routing defines a control plane network architecture and
+ can be applied to an existing MPLS based dataplane. In the MPLS networks,
+ segments are encoded as MPLS labels and are imposed at the ingress router.
+ MPLS labels are exchanged and populated by IGPs like IS-IS.Segment Routing
+ as per RFC8667 for MPLS dataplane. It supports IPv4, IPv6 and ECMP and has
+ been tested against Cisco & Juniper routers.however,this deployment is still
+ EXPERIMENTAL for FRR .
+
+
+IS-IS SR Configuration
+----------------------
+
+Segment routing (SR) is used by the IGP protocols to interconnect network
+devices, below configuration shows how to enable SR on IS-IS:
+
+
+.. note:: ``Known limitations:``
+
+ No support for level redistribution (L1 to L2 or L2 to L1)
+
+ No support for binding SID
+
+ No support for SRLB
+
+ Only one SRGB and default SPF Algorithm is supported
+
+
+
+.. cfgcmd:: set protocols isis segment-routing global-block <high-label-value
+ | low-label-value> <label-value>
+
+ Set the Segment Routing Global Block i.e. the label range used by MPLS to
+ store label in the MPLS FIB for Prefix SID. Note that the block size may
+ not exceed 65535.
+
+.. cfgcmd:: set protocols isis segment-routing local-block <high-label-value
+ | low-label-value> <label-value>
+
+ Set the Segment Routing Local Block i.e. the label range used by MPLS to
+ store label in the MPLS FIB for Prefix SID. Note that the block size may
+ not exceed 65535.Segment Routing Local Block, The negative command always
+ unsets both.
+
+.. cfgcmd:: set protocols isis segment-routing maximum-label-depth <1-16>
+
+ Set the Maximum Stack Depth supported by the router. The value depend of
+ the MPLS dataplane.
+
+.. cfgcmd:: set protocols isis segment-routing prefix <address> index value
+ <0-65535>
+
+ A segment ID that contains an IP address prefix calculated by an IGP in the
+ service provider core network. Prefix SIDs are globally unique, this value
+ indentify it
+
+.. cfgcmd:: set protocols isis segment-routing prefix <address> index
+ <no-php-flag | explicit-null| n-flag-clear>
+
+ prefix. The ‘no-php-flag’ means NO Penultimate Hop Popping that allows SR
+ node to request to its neighbor to not pop the label. The ‘explicit-null’
+ flag allows SR node to request to its neighbor to send IP packet with the
+ EXPLICIT-NULL label. The ‘n-flag-clear’ option can be used to explicitly
+ clear the Node flag that is set by default for Prefix-SIDs associated to
+ loopback addresses. This option is necessary to configure Anycast-SIDs.

+
+OSPF SR Configuration
+----------------------
+
+Segment routing (SR) is used by the IGP protocols to interconnect network
+devices, below configuration shows how to enable SR on OSPF:
+
+.. cfgcmd:: set protocols ospf parameters opaque-lsa
+
+ Enable the Opaque-LSA capability (rfc2370),necessary to transport label
+ on IGP
+
+
+.. cfgcmd:: set protocols ospf segment-routing global-block <high-label-value

+
+ Set the Segment Routing Global Block i.e. the label range used by MPLS to
+ store label in the MPLS FIB for Prefix SID. Note that the block size may
+ not exceed 65535.
+
+.. cfgcmd:: set protocols ospf segment-routing local-block <high-label-value
+ | low-label-value> <label-value>
+
+ Set the Segment Routing Local Block i.e. the label range used by MPLS to

+
+.. cfgcmd:: set protocols ospf segment-routing prefix <address> index value
+ <0-65535>
+
+ A segment ID that contains an IP address prefix calculated by an IGP in the
+ service provider core network. Prefix SIDs are globally unique, this value
+ indentify it
+
+.. cfgcmd:: set protocols ospf segment-routing prefix <address> index
+ <no-php-flag | explicit-null| n-flag-clear>
+

+ node to request to its neighbor to not pop the label. The ‘explicit-null’
