Automatic discovery of peers, and thus less unique configuration. You don't need to configure each peer individually, just the interface. If you do unnumbered links, you don't even need to allocate link networks for your routing links, giving even less unique configuration. Just set interfaces xe-0/0/17.1 family inet unnumbered-address lo0.1 set interfaces xe-0/0/17.1 family inet6 set protocols ospf area A.B.C.D interface xe-0/0/17.1 interface-type p2p set protocols ospf3 area A.B.C.D interface xe-0/0/17.1 interface-type p2p and you're done. The nice thing is that the only unique piece of configuration is the interface name. Doing unnumbered links for BGP seems to at least be more complicated, but Cumulus Linux is supposed to have support for it, making it as easy to configure as OSPF. (https://blog.ipspace.net/2015/02/bgp-configuration-made-simple-with.html; I've never used Cumulus, just read about it.) /Bellman
