Hi list What is the recommended way to configure mtu for veth pairs via systemd-networkd?
From https://www.freedesktop.org/software/systemd/man/systemd.netdev.html MTUBytes for veth is supported in the [NetDev] configuration, however given the following foo.netdev file: [NetDev] Name=foo Kind=veth MTUBytes=9000 [Peer] Name=bar it looks like the relevant mtu does not get set for the peer, i.e. 11: bar@foo: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 06:93:0c:33:db:64 brd ff:ff:ff:ff:ff:ff 12: foo@bar: <BROADCAST,MULTICAST,M-DOWN> mtu 9000 qdisc noop state DOWN group default qlen 1000 link/ether 7e:75:6d:ba:ae:ae brd ff:ff:ff:ff:ff:ff Is it possible to set the mtu for the peer via the .netdev files, or should the .network files ([Link] section) be used instead? For tun, or tap devices the docs explicitly mention the above approach, but not for veths. I’m using systemd 245 (245.4-4ubuntu3.7).
