Description For Ethernet interfaces, enable the local address to be derived from the specified interface Configuring an unnumbered Ethernet interface enables IP processing on the interface without assigning an explicit IP address to the interfaceI have a business DSL connection with a subnet I need the WAN interface to be a PPPoE connection to a modem and the LAN interface to be an IP on the subnet my ISP gives me So the WAN interface does not have an IP addressIPv6 has unnumbered interfaces built in (they are called Link Local Addresses), and intraAS routing protocols like OSPF have to use them (so it's impossible to mangle your implementation in a way that would make numbered IPv6 pointtopoint links mandatory) And now for the claims The Cumulus documentation claims

The main idea of unnumbered interfaces is that you don't configure any specific IPv4/IPv6 address at interface but you rather say interface to use IP address from different interface, which is typically system for Nokia (AlcatelLucent) SR OS or loopback 0 in Cisco IOS XRA disadvantage is that with an unnumbered interface like S0 for an example, you can not telnet to that interface no ip, no telnet That can be a problem when trying to troubleshoot a network link I have times where I needed to telnet to the serial interface and then jump from thereIp unnumbered Ethernet 0 The ip unnumbered interface mode command borrows the IP address from the specified interface to the interface on which the command has been configured Use of the ip unnumbered command results in the IP address being shared by two interfaces

Jeremy, it's a recommended tactic on the isp router to use "ip unnumbered" under the vtemplate and use another interface (ie loopback) for the ip address I don't know if this has been fixed in later IOS, but there was a limit of max 6 interfaces using the same ip address, unless "ip unnumbered" was usedWhen IP unnumbered is configured, routes learned through the IP unnumbered interface have the interface as the next hop instead of the source address of the routing update Thus we avoid an invalid next hop address problem due to the source of the routing update coming from a next hop that is not directly connectedDoes OPNsense support unnumbered PPPoE interfaces?
