Abstract: A first network device may receive a first advertisement of a network destination from a second network device and may detect multihoming with the second network device. The second network device may detect the multihoming with the first network device. The first network device and the second network may enable egress protection for the multihoming. The first network device may allocate, from a first pool, a protection group identifier for a group of multihomed network devices and may allocate, from a second pool, a network destination identifier for the network destination. The first network device may provide, to a network and the second network device, a second advertisement that includes the protection group identifier and the network destination identifier. The protection group identifier and the network destination identifier may cause the network to direct traffic for the network destination, via the group of multihomed network devices.

Abstract: A network device may receive, from a first neighbor network device, information indicating that the network device is to remove a bit indexed explicit replication (BIER) header and a BIER label from a multicast packet prior to transmitting the multicast packet to the first neighbor network device. The network device may receive the multicast packet from a second neighbor network device, where the multicast packet includes the BIER header and the BIER label and is to be transmitted to the first neighbor network device, and where the network device, the first neighbor network device, and the second neighbor network device are included in a same BIER domain. The network device may remove the BIER header and the BIER label from the multicast packet, and may transmit the multicast packet to the first neighbor network device after removing the BIER header and the BIER label from the multicast packet.

Abstract: In some implementations, a network device may determine a route distinguisher (RD) that is associated with a bit index explicit replication (BIER) domain, wherein the network device participates in the BIER domain and one or more BIER sub-domains of the BIER domain. The network device may identify BIER sub-domain information associated with a BIER sub-domain of the one or more BIER sub-domains of the BIER domain. The network device may identify proxy information that is associated with the BIER sub-domain. The network device may send an advertisement that includes a BIER prefix of the network device, the BIER sub-domain information, the RD, and the proxy information. Sending the advertisement is to permit a receiving network device to store the proxy information in a bit index forwarding table (BIFT) of the receiving network device.

Abstract: A network device identifies an Open Shortest Path First (OSPF) link between the network device and a layer 2 network as one of a point-to-multipoint over broadcast interface or a point-to-multipoint over non-broadcast multi access (NBMA) interface, and performs database synchronization and neighbor discovery and maintenance using one of a broadcast model or a NBMA model. The network device also generates a link-state advertisement for the network device, where the link-state advertisement includes a separate link description for each point-to-point link within the layer 2 network; and sends the link-state advertisement to each fully adjacent neighbor in the layer 2 network.
Abstract translation: 网络设备将网络设备和第2层网络之间的开放最短路径优先（OSPF）链路标识为点对多点广播接口之间或通过非广播多路访问（NBMA）的点对多点之一， 接口，并使用广播模型或NBMA模型之一执行数据库同步和邻居发现和维护。 网络设备还为网络设备生成链路状态广告，其中链路状态广告包括针对第2层网络内的每个点到点链路的单独的链路描述; 并向第2层网络中的每个完全相邻的邻居发送链路状态通告。

Abstract: In some implementations, a network device may receive, from a first other network device, a route that includes a label, a prefix, and a next-hop identifier. The network device may generate, based on receiving the route, a composite tunnel attribute that includes an identifier of the network device and a label allocated by the network device. The network device may modify, based on generating the composite tunnel attribute, the route to cause the composite tunnel attribute to be included in the route. The network device may send, based on modifying the route, the route to a second other network device.

Abstract: In some implementations, a first network device may determine a route distinguisher (RD) and a route target (RT) associated with an address prefix that is to be included in a global routing and forwarding table. The first network device may send an advertisement that includes the address prefix, the RD, and the RT, wherein: the RT indicates that the address prefix is to be included in a global routing and forwarding table of a receiving network device.

Abstract: A network device may transmit, to a first neighbor network device, information indicating that the network device supports bit indexed explicit replication (BIER), where the network device does not support BIER. The network device may receive, from the first neighbor network device, a multicast packet that includes a first BIER label associated with the network device. The network device may replace the first BIER label with a second BIER label associated with a second neighbor network device, and may transmit the multicast packet to the second neighbor network device. The second neighbor network device may be to tunnel the multicast packet to a third neighbor network device that supports BIER.

Abstract: A network device receives multicast packets that include information identifying destinations in the network, identifies next hops associated with the destinations, and populates a cache with the destinations and addresses of the identified next hops. The network device receives a particular multicast packet that includes information identifying particular destinations included in the cache, identifies one or more next hops for the particular destinations from the cache, and forwards the particular multicast packet to the identified one or more next hops to permit the identified one or more next hops to forward the multicast packet toward the particular destinations.

Abstract: An interworking network device receives from a first other network device associated with an MPLS domain, a route that includes a label, a prefix, and a next-hop identifier that indicates the first other network device. The interworking network device thereby generates a prefix SID attribute that includes a SID value and information indicating a structure of the SID value, wherein a LOC portion of the SID value identifies the interworking network device, and a first sub-portion of a FUNCT portion of the SID value identifies an endpoint behavior of the interworking network device in association with the first other network device. The interworking network device modifies the route to cause the next-hop identifier to indicate the interworking network device, and to cause the route to include the prefix SID attribute. The interworking network device thereby sends the route to a second other network device associated with an SRv6 domain.
