SR MPLS policy creation and application.
Create an SR policy. An SR policy can be either of 'default' type or 'spray' type An SR policy has attached a list of SID lists. In case the SR policy is a default one it will load balance among them. An SR policy has associated a BindingSID. In case any packet arrives with MPLS_label == BindingSID then the SR policy associated to such bindingSID will be applied to such packet. Also, a BSID can be associated with a (Next-Hop, Color)

Creates a Segment List and adds it to an SR policy.
Creates a Segment List and adds it to the SR policy. Notice that the SL are not necessarily unique. Hence there might be two Segment List within the same SR Policy with exactly the same segments and same weight.
sr_policy | is the SR policy where the SL will be added |
sl | is a vector of IPv6 addresses composing the Segment List |
weight | is the weight of the SegmentList (for load-balancing purposes) |
is_encap | represents the mode (SRH insertion vs Encapsulation) |

Create a new SR policy.
bsid | is the bindingSID of the SR Policy |
segments | is a vector of MPLS labels composing the segment list |

Modify an existing SR policy.
The possible modifications are adding a new Segment List, modifying an existing Segment List (modify the weight only) and delete a given Segment List from the SR Policy.
bsid | is the bindingSID of the SR Policy |
fib_table | is the VRF where to install the FIB entry for the BSID |
operation | is the operation to perform (among the top ones) |
segments | is a vector of IPv6 address composing the segment list |
sl_index | is the index of the Segment List to modify/delete |
weight | is the weight of the sid list. optional. |
