Adding the route won't work, the only way I've gotten a /31 to work is like Roger suggested... Say your subnet is 1.1.1.42/31 End A: Address: 1.1.1.42 Network: 1.1.1.43 End B: Address: 1.1.1.43 Network: 1.1.1.42 No routes added or needed. I've just been through the same exercise due to needing to conserve address space. In the end I wasn't comfortable with using /31s without full support (what else will break one day..?) So I've given the core and edge /32 loopbacks from our address space and used the 100.64.0.0/10 space for the links. -----Original Message----- From: Public <public-bounces@talk.mikrotik.com.au> On Behalf Of Christopher Hawker via Public Sent: Monday, January 8, 2024 7:26 PM To: MikroTik Australia Public List <public@talk.mikrotik.com.au> Cc: Christopher Hawker <chris@thesysadmin.au> Subject: Re: [MT-AU Public] /31 Deployments for Point-to-Point links I tried doing that; adding /32 addresses to both ends then creating routes to the other address via the respective interfaces.

Can you setup a /32, which looks like a /31? (or is that what you have?)
eg. address xx.34 network xx.35

Hey all,
Trying to stand-up a BGP session between a CCR2004-1G-12S+2XS and a CCR2004-16G-2S+ using a /31 for the link. I'm able to ping across the link no problem, however, the BGP session doesn't establish. I'm attempting to move an existing session from a /30 where it works in order to conserve IP space. Is there some skullduggery going on, or is 7.13 just not RFC3021-compliant?
