There are deployments where the Layer-3 interface on which IGP
operates is a Layer-2 interface bundle. Existing IGP advertisements
only support advertising link attributes of the Layer-3 interface.
If entities external to IGP wish to control traffic flows on the
individual physical links that comprise the Layer-2 interface bundle,
link attribute information about the bundle members is advertised by
IGP extensions for Layer-2 (L2) bundle.
When Segment Routing over IPv6 (SRv6) is used with Layer-2 interface
bundle to control traffic flows on the individual member links, the
SRv6 SIDs which represent the Layer 2 member links of the L2 bundle
needs to be advertised in IGP.
This document proposes the IGP extensions to advertise the SRv6 SIDs
of the Layer 2 (L2) bundle member links.
