evpn mh mac holdtime time no evpn mh mac holdtime time \[purpose] configure the retention time for mac addresses synchronized via evpn \[parameter] parameter description time unit seconds, range 0 86400, default 60 \[view] interface view、lag view \[use cases] sonic# evpn mh mac holdtime 60 evpn mh neigh holdtime evpn mh neigh holdtime \[command] evpn mh neigh holdtime time no evpn mh neigh holdtime time \[purpose] configure the retention time for arp entries synchronized via evpn \[parameter] parameter description time unit seconds, range 0 86400, default 60 \[view] interface view、lag view \[use cases] sonic# evpn mh neigh holdtime 60 evpn mh es id evpn mh es id \[command] evpn mh es id es id no evpn mh es id \[purpose] configure the esi value for the interface in a multi homing scenario, interfaces belonging to the same multi homing group must have the same esi value the esi value, which uniquely identifies an interface in a multi homing group, is formed by combining the es id and the es sys mac \[parameter] parameter description es id range 1 16777215 \[view] interface view、lag view \[use cases] sonic(config)# interface ethernet 3 sonic(config if 3)# evpn mh es id 101 evpn mh es sys mac evpn mh es sys mac \[command] evpn mh es sys mac es sys mac no evpn mh es sys mac \[purpose] configure the es sys mac value for the interface in a multi homing scenario, the es sys mac for interfaces in the same group must be identical the esi value, which is used to identify an interface in a multi homing group, is formed by combining the es id and the es sys mac \[parameter] parameter description es sys mac the es sys mac address for the interface must be in mac address format \[view] interface view、lag view \[use cases] sonic(config)# interface ethernet 3 sonic(config if 3)# evpn mh es sys mac 00 11 22 33 44 55 evpn mh es df pref evpn mh es df pref \[command] evpn mh es df pref priority no evpn mh es df pref \[purpose] configure the priority of interface \[parameter] parameter description priority range 1 65535, default 32767 \[view] interface view、lag view \[usage scenario] in a multi homing scenario, interfaces within the multi homing group negotiate the designated forwarder (df) role an interface with a higher priority value has higher precedence; when priorities are equal, the vtep with the smaller ip address has higher precedence \[use cases] sonic(config)# interface ethernet 3 sonic(config if 3)# evpn mh es df pref 100 mh group id mh group id \[command] mh group id id no mh group id \[purpose] configure the interface on the leaf device to an mh group \[parameter] parameter description id range 1 16777215 \[view] interface view、lag view \[usage scenario] for dual homed terminals connected to different leaf devices, configure the same mh group id on the respective interfaces to guarantee successful terminal onboarding and seamless migration \[notes] executing this command effectively sets the es id and es sys mac the key distinction is that the mh group approach applies a uniform es sys mac to all leaf interfaces, while manually configuring es sys mac allows for per interface assignment \[use cases] sonic(config)# interface ethernet 3 sonic((config if 3)# mh group id 1 address family l2vpn evpn address family l2vpn evpn \[command] address family l2vpn evpn \[purpose] enter the evpn address family view \[view] bgp view \[usage scenario] when using bgp to dynamically establish vxlan tunnels, this command must be executed in the bgp view to enter the evpn address family configuration view and establish bgp evpn peers \[use cases] sonic(config)# router bgp 65100 sonic(config router)# address family l2vpn evpn sonic(config router af)# neighbor activate neighbor activate \[command] neighbor { a b c d | x\ x x \ x| string } activate no neighbor { a b c d | x\ x x \ x| string } activate \[purpose] enable the configuration of a bgp evpn peer \[parameter] parameter description a b c d ipv4 address x\ x x \ x ipv6 address string specify the name of the peer group \[view] evpn address family view \[use cases] sonic(config)# router bgp 65100 sonic(config router)# address family l2vpn evpn sonic(config router af)#
