You can issue tracert 8.8.8.8 from your PC and find out the next hop IP address, that would be your next hop (gateway IP address) IP address, after that, issue command arp -a, and see that IP address mapped to which MAC address and that MAC address is the next hop (gateway). Following is just for example.

Set Router IP Address? Uverse gateway -> Google Wifi device -> 15$ switch to wired devices Of course the mesh branches off the Google Wifi device. All devices behind the Google Wifi can see each other. So, I'll use MAC address filtering, for example and tie that to an IP over DCHP. I'll also need to lock down the modem somehow. The configuration of each IRB interface can also include a virtual gateway address (VGA), which creates a default Layer 3 virtual gateway with the specified IP address. Understanding the MAC Addresses For a Default Virtual Gateway in an EVPN-VXLAN Topology. In an Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) topology with a two-layer IP fabric, an MX Series router or a QFX10000 switch can function as a Layer 3 VXLAN gateway on which you can configure integrated routing and bridging (IRB) interfaces. The configuration of each IRB interface can also include a virtual gateway address (VGA), which creates a default Layer 3 virtual gateway with the specified IP address. Through the IRB interface with which it is configured, the default virtual gateway enables the communication between non-virtualized hosts, virtual machines (VMs), and servers in different VXLANs or IP subnetworks. When you configure a VGA for an IRB interface, the Layer 3 VXLAN gateway automatically generates IPv4 media access control (MAC) address 00:00:5E:00:01:01 or IPV6 MAC address 00:00:5E:00:02:01 for that particular virtual gateway. (This topic refers to the virtual gateway MAC address as a virtual MAC.) The automatically generated virtual MAC is not included as the source MAC address in packets generated by the Layer 3 VXLAN gateway. Instead, data packets and the source MAC address field in the outer Ethernet header of Address Resolution Protocol (ARP) replies and neighbor advertisement packets include the MAC address for the IRB interface. (This topic refers to the MAC address for the IRB interface as the IRB MAC.) When an ARP reply includes the IRB MAC as the source MAC address instead of the virtual MAC, an issue might arise in an EVPN-VXLAN topology with a two-layer IP fabric. For example, in the topology shown in, an MX Series router and a QFX10000 switch function as Layer 3 VXLAN gateways, and four QFX5100 switches function as Layer 2 VXLAN gateways. Also included in the topology are three intermediary Layer 2 switches, in this case, EX4300 switches, to which hosts are connected. Figure 1: EVPN-VXLAN Topology With Two-Layer IP Fabric. On the MX Series router, an IRB interface named irb.1 has a MAC address of 00:05:85:00:53:01 and a VGA of 10.2.1.254. The MX Series router automatically generates the MAC address 00:00:5e:00:01:01 for the default virtual gateway. In this topology, irb.1 on the MX Series router receives an ARP request from host 1. In its ARP reply, the MX Series router includes the following: • Source MAC address in outer Ethernet header: 00:05:85:00:53:01 (IRB MAC) → intermediary Layer 2 switch EX1 learns this MAC address. • Sender MAC address within ARP reply packet: 00:00:5e:00:01:01 (virtual MAC) → intermediary Layer 2 switch EX1 cannot see this MAC address, and therefore, does not learn it. When intermediary Layer 2 switch EX1 receives the ARP reply, it learns only the source MAC address (IRB MAC). As a result, if host 1 sends packets that include the virtual MAC in the header, EX1 is unable to find the virtual MAC in its MAC table. Therefore, EX1 floods the domain with unknown-unicast packets. Note The flooding of unknown-unicast packets is not an issue in EVPN-VXLAN topologies with a collapsed IP fabric. That is, a topology in which a single layer of QFX10000 switches function as both Layer 3 and Layer 2 VXLAN gateways. ![]() In the collapsed IP fabric topology, hosts are directly connected to the Layer 3 and Layer 2 VXLAN gateways. Further, each IRB interface is typically configured with an IP address and a static MAC address. Mac dont use trash for google drive. Run mysql and access deny for user mac mac.
