I will do tests to be sure. I don't known if users have usecases with 2 physical interfaces in 1 vmbr without bonding ? Main impacted users are public hosting where ip/mac couple is filtered, so they never have more than 1 interface. some doc about this option: https://support.cumulusnetworks.com/hc/en-us/articles/360005695794- Cumulus-Linux-Derivation-of-MAC-Address-for-a-Bridge Le mercredi 14 juillet 2021 à 08:19 +0200, Thomas Lamprecht a écrit : > On 14.07.21 07:38, Thomas Lamprecht wrote: > > On 13.07.21 07:16, alexandre derumier wrote: > > > Hi, > > > it seem that it's possible to enable some policy on bridge in > > > ifupdown2 > > > > > > > > > cumulus linux distro for example, have this policy > > > > > > $ cat /var/lib/ifupdown2/policy.d/bridge.json > > > { > > > "bridge": { > > > "module_globals": { > > > "warn_on_untagged_bridge_absence": "yes", > > > "vxlan_bridge_default_igmp_snooping": "off", > > > "allow_arp_nd_suppress_only_on_vxlan": "yes", > > > "bridge_set_static_mac_from_port": "yes" > > > }, > > > "defaults": { > > > "bridge-stp": "on", > > > "bridge-vlan-stats" : "on", > > > "bridge-mcstats" : "on", > > > "bridge-portprios": "8", > > > "bridge-hashel": "4096", > > > "bridge-hashmax": "4096", > > > "bridge-ageing": "1800" > > > } > > > } > > > } > > > > > > > > > bridge_set_static_mac_from_port could be usefull to reuse > > > physical > > > interface mac on bridge. > > > > > > > sounds good in theory, but to which port?
