Abstract
BIER-TE extends BIER with tree engineering capabilities and can be supported by almost the same hardware. However, a bitstring in BIER- TE hold bits for BFERs and links, which effects that the size of supportable topologies in terms of BFERs is smaller for BIER-TE than for BIER. While for BIER, subsets can be utilized to improve scaling to large multicast domains, this mechanism requires adaptation for BIER-TE. In this document, requirements for BIER-TE subsets are defined, a mechanism is described for how BIER-TE packets can reach their subsets using tunneling, and 1:1 protection for the entire BIER-TE multicast tree is explained. The concept utilizes egress protection for reaching a subset when the ingress BFIR of the subset fails.
