SRv6 uSID Linux implementation Home Page
The SRv6 “micro segment” (uSID for short) solution is an extension to the SRv6 Network Programming model (see below). It allows expressing SRv6 segments with a very compact and efficient representation, for example using two bytes for uSID instead of using a normal IPv6 address (16 bytes) for a regular SRv6 segment.
The processing of micro segments is performed by the Linux kernel, extending the current SRv6 implementation. The iproute2 userspace tool has been modified to support the configuration of the SRv6 uSIDs. The usage of the new iproute2 CLI commands is explained here.
