This is an implementation of the IS-IS SR draft [1] for FRR. The following features are supported: * IPv4 and IPv6 Prefix-SIDs; * IPv4 and IPv6 Adj-SIDs and LAN-Adj-SIDs; * Index and absolute labels; * The no-php and explicit-null Prefix-SID flags; * Full integration with the Label Manager. Known limitations: * No support for Anycast-SIDs; * No support for the SID/Label Binding TLV (required for LDP interop). * No support for persistent Adj-SIDs; * No support for multiple SRGBs.
