A device, comprising: one or more processors configured to: receive one or more route identifiers from one or more other devices, the one or more route identifiers including: one or more range identifiers associated with one or more ranges of broadcast domain identifiers configured on the one or more other devices, or one or more configuration identifiers associated with one or more Ethernet segment identifier, ESI, configurations of the one or more other devices; identify the one or more range identifiers or the one or more configuration identifiers included in the one or more route identifiers; and select a designated forwarder from among the device and the one or more other devices based on the identified one or more range identifiers or based on the identified one or more configuration identifiers, the designated forwarder being the same designated forwarder selected by at least one other device, the one or more processors, when selecting the designated forwarder, being configured to: exclude at least one device of the one or more other devices from being selected as the designated forwarder based on: the range identifier received from the at least one device being different than a range identifier configured on the device and one or more other devices, or the configuration identifier received from the at least one device being different than a configuration identifier configured on the device and one of the one or more other devices; provide a message to the at least one device to prevent the at least one device from selecting the designated forwarder; and providing, to the at least one device, information identifying the designated forwarder. receive one or more route identifiers from one or more other devices, the one or more route identifiers including: one or more range identifiers associated with one or more ranges of broadcast domain identifiers configured on the one or more other devices, or one or more configuration identifiers associated with one or more Ethernet segment identifier, ESI, configurations of the one or more other devices; one or more range identifiers associated with one or more ranges of broadcast domain identifiers configured on the one or more other devices, or one or more configuration identifiers associated with one or more Ethernet segment identifier, ESI, configurations of the one or more other devices; identify the one or more range identifiers or the one or more configuration identifiers included in the one or more route identifiers; and select a designated forwarder from among the device and the one or more other devices based on the identified one or more range identifiers or based on the identified one or more configuration identifiers, the designated forwarder being the same designated forwarder selected by at least one other device, the one or more processors, when selecting the designated forwarder, being configured to: exclude at least one device of the one or more other devices from being selected as the designated forwarder based on: the range identifier received from the at least one device being different than a range identifier configured on the device and one or more other devices, or the configuration identifier received from the at least one device being different than a configuration identifier configured on the device and one of the one or more other devices; the range identifier received from the at least one device being different than a range identifier configured on the device and one or more other devices, or the configuration identifier received from the at least one device being different than a configuration identifier configured on the device and one of the one or more other devices; provide a message to the at least one device to prevent the at least one device from selecting the designated forwarder; and providing, to the at least one device, information identifying the designated forwarder. <EOS>
