  • SYSTEMS AND METHODS FOR ADVERTISING IP VERSION 6 NETWORK LAYER ROUTING INFORMATION WITH AN IP VERSION 4 NEXT HOP ADDRESS
    Publication number: 20230370372
    Abstract: In some implementations, a first network device may encode Internet protocol version 4 (IPv4) next hop of Internet protocol version 6 (IPv6) information. The first network device may advertise the IPv6 information to a second network device via an IPv4 border gateway protocol. The first network device may forward an IPv6 packet via an IPv4 interface associated with the first network device based on advertising the IPv6 information.

  • SYSTEMS AND METHODS FOR CONNECTING IPV4 ISLANDS OVER AN IPV6 CORE NETWORK USING IPV4 PROVIDER EDGE ROUTERS
    Publication number: 20230353480
    Abstract: In some implementations, a first network device may encode Internet Protocol version 4 (IPv4) network layer reachability information (NLRI) using Internet Protocol version 6 (IPv6) next hop encoding to generate encoded IPv4 NLRI. The first network device may include information indicating border gateway protocol (BGP) labeled unicast (BGP-LU) in the encoded IPv4 NLRI. The first network device may advertise the encoded IPv4 NLRI. The first network device may establish a communication session with a second network device, wherein the communication session is established via an IPv6 core network. The first network device may forward, via the communication session, one or more IPv4 packets using the encoded IPv4 NLRI.

  • SYSTEMS AND METHODS FOR ADVERTISING INTERNET PROTOCOL (IP) VERSION 4 NETWORK LAYER ROUTING INFORMATION WITH AN IP VERSION 6 NEXT HOP ADDRESS
    Publication number: 20230275869
    Abstract: A first network device associated with a network may establish an Internet protocol version 6 Multiprotocol BGP session with a second network device associated with the network. The first network device and second network device are both capable of forwarding both IPv4 and IPv6 packets with only an IPv6 address configured on the interface of both the first network device and second network device. The first network device may exchange Multiprotocol Reachability capability with second network device for corresponding 2-tuple Address Family Identifier/Subsequent Address Family Identifier. The first network device may advertise Internet protocol version 4 network layer reachability information and may advertise Internet protocol version 6 network layer reachability information with IPv6 extended next hop encoding using Internet Assigned Numbering Authority assigned capability code value 5 to second network device.
