FRAMEWORK FOR BIER FAST REROUTE

A method implemented by a network node in a BIER domain includes obtaining, by a control plane of the network node, an IP LFA from a FIB or RIB through a first interface, using, by the control plane of the network node, the IP LFA to build a BIFTe when the IP LFA is an expected type, accessing, by t...

description A method implemented by a network node in a BIER domain includes obtaining, by a control plane of the network node, an IP LFA from a FIB or RIB through a first interface, using, by the control plane of the network node, the IP LFA to build a BIFTe when the IP LFA is an expected type, accessing, by the control plane of the network node, a BIER network topology in an LSDB through a second interface, computing an LFA of the expected type, and using the LFA to build the BIFTe when the IP LFA is not of the expected type, updating, by the control plane of the network node, the BIFTe in a data plane of the network node through a third interface; and forwarding, by the data plane of the network node, BIER packets using the BIFTe to avoid a failure.
