  • Patent number: 11606333
    Abstract: Systems and techniques are provided for synchronizing DHCP snoop information. In some examples, a method can include, performing, by a first PE device from a plurality of PE devices, DHCP snooping of a first plurality of DHCP messages between a DHCP client and a DHCP server, wherein the plurality of PE devices is part of an ethernet segment for multihoming the DHCP client. In some aspects, the method includes determining, based on snooping the first plurality of DHCP messages, an association between an IP address corresponding to the DHCP client and a MAC address corresponding to the DHCP client. In some examples, the method includes sending, by the first PE device to at least one other PE device from the plurality of PE devices, a first route advertisement that includes the association between the IP address corresponding to the DHCP client and the MAC address corresponding to the DHCP client.

  • Publication number: 20220393938
    Abstract: Techniques for connectivity issue remediation are provided. A first link trace message is transmitted from a source end point to a destination end point. A first topology graph for a network is generated based on the first link trace message, and a presence of a connectivity issue in the network is detected. A second link trace message is transmitted from the source end point to the destination end point. A second topology graph for the network is automatically generated based on second link trace message, and a component in the network that caused the connectivity issue is identified based on comparing the first and second topology graphs.

  • Patent number: 11381500
    Abstract: Embodiments of the present disclosure relate to assisting forwarding of multicast traffic over Ethernet Virtual Private Network (EVPN) from a multicast source to a host multi-homed to multiple provider edge (PE) devices. Embodiments are based on the inclusion of an Ethernet Segment Identification (ESI) to EVPN type-6 routes advertised by PE devices which received a multicast Join message. Other PE devices receiving such routes are able to determine whether they belong to the ES identified by the ESI and to determine whether they are designated forwarders (DFs) for the host. Furthermore, PE devices which are the DFs are configured to re-originate the EVPN type-6 routes, i.e. re-send the advertisements, indicating themselves as DFs. This ensures that a remote PE device associated with the multicast source will also send multicast traffic to such DF PE devices, which, in turn, would allow the multicast traffic to successfully reach the host.

    Abstract: Access-side loop mitigation may be provided. First, a first edge device may determine that a duplicate host exists on a network. Then the first edge device may detect a loop in response to determining that the duplicate host exists on the network. Detecting the loop may comprise sending a message on a plurality of access-side ports of the first edge device and then receiving, in response to sending the message on the plurality of access-side ports of the first edge device, a response on a first access-side port of the plurality of access-side ports of the first edge device. Next, the first edge device may mitigate the detected loop in response to receiving the response.
