Re: [Babel-users] Error when running babeld
Using UBUNTU Linux 18.04: $sudo apt-get install babeld Babeld is already the newest version (1.7.0-1build1). So the Ubunti repos for the latest babeld are 1.7.0. -Original Message- From: Dave Taht Sent: Monday, February 17, 2020 9:42 AM To: Callahan, David (US) Cc: Juliusz Chroboczek ; Babel-users@alioth-lists.debian.net Subject: Re: [Babel-users] Error when running babeld *** WARNING *** EXTERNAL EMAIL -- This message originates from outside our organization.

Hi, > I don't want IPV6 on the system. It’s 2020… I’m sorry, I’m not sure how to configure babeld to use IPv4 as its transport layer. Juliusz, is that even implemented? I think the multicast address need be set to IPv4 too (224.0.0.111) but that is not implemented in babeld, so you don’t have neighbor discovery. I’m not sure if the Bird implementation https://bird.network.cz/ supports IPv4 as its transport layer. -- Antonin PS: tonight I’ll make a toast to the universal deployment of IPv6. ___ Babel-users mailing list Babel-users@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
