A method comprising: detecting a failure in a first egress node (621, 721) of a point-to-multipoint, P2MP, label switched path, LSP, wherein the P2MP LSP comprises a plurality of first egress nodes, wherein each first egress node (621, 721) is paired with a second egress node (622, 722), wherein each of the second egress node (622, 722) is designated as the backup egress node for establishing a backup LSP to provide protection against failure of the first egress node (621, 721) paired with the second egress node (622, 722); and transmitting a data packet destined for the first egress node (621, 721) of the P2MP LSP and to be forwarded to a client on a backup LSP to a second egress node (622, 722) of the P2MP LSP when the first egress node (621, 721) of the P2MP LSP fails; wherein the P2MP LSP comprises a previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP, wherein the previous-hop node (615, 715) is coupled to the second egress node (622, 722) of the P2MP LSP via a backup LSP, wherein the second egress node (622, 722) of the P2MP LSP and the first egress node (621, 721) of the P2MP LSP are both coupled to an external client (650, 750); wherein the previous-hop node (615, 715) and the second egress node (622, 722) of the P2MP LSP are configured to ensure data delivery to the external client (650, 750) when the first egress node of the P2MP LSP fails, wherein the previous hop node is configured to detect a failure in the first egress node (621, 721) using a Bi-directional Forwarding Detection, BFD, interface, wherein the backup LSP is a point-to-point, P2P, bypass tunnel from the previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP to the second egress node (622, 722) of the P2MP LSP; wherein the first egress node is informed of the second egress node (622, 722), and the first egress node sends information about forwarding the data packet to a client (650, 750) to the second egress node (622, 722) of the P2MP LSP via the previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP in a RSVP-TE RESV message and the previous-hop node (615, 715) sends the information to the second egress node (622, 722) of the P2MP LSP in a RSVP-TE PATH message. detecting a failure in a first egress node (621, 721) of a point-to-multipoint, P2MP, label switched path, LSP, wherein the P2MP LSP comprises a plurality of first egress nodes, wherein each first egress node (621, 721) is paired with a second egress node (622, 722), wherein each of the second egress node (622, 722) is designated as the backup egress node for establishing a backup LSP to provide protection against failure of the first egress node (621, 721) paired with the second egress node (622, 722); and transmitting a data packet destined for the first egress node (621, 721) of the P2MP LSP and to be forwarded to a client on a backup LSP to a second egress node (622, 722) of the P2MP LSP when the first egress node (621, 721) of the P2MP LSP fails; wherein the P2MP LSP comprises a previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP, wherein the previous-hop node (615, 715) is coupled to the second egress node (622, 722) of the P2MP LSP via a backup LSP, wherein the second egress node (622, 722) of the P2MP LSP and the first egress node (621, 721) of the P2MP LSP are both coupled to an external client (650, 750); wherein the previous-hop node (615, 715) and the second egress node (622, 722) of the P2MP LSP are configured to ensure data delivery to the external client (650, 750) when the first egress node of the P2MP LSP fails, wherein the previous hop node is configured to detect a failure in the first egress node (621, 721) using a Bi-directional Forwarding Detection, BFD, interface, wherein the backup LSP is a point-to-point, P2P, bypass tunnel from the previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP to the second egress node (622, 722) of the P2MP LSP; wherein the first egress node is informed of the second egress node (622, 722), and the first egress node sends information about forwarding the data packet to a client (650, 750) to the second egress node (622, 722) of the P2MP LSP via the previous-hop node (615, 715) of the first egress node (621, 721) of the P2MP LSP in a RSVP-TE RESV message and the previous-hop node (615, 715) sends the information to the second egress node (622, 722) of the P2MP LSP in a RSVP-TE PATH message.
