Configuring VLANs This chapter describes how to configure virtual LANs (VLANs) on Cisco NX-OS devices. This chapter includes the following sections: Information About VLANs Note Beginning with Cisco Release 5.2(1) for Cisco Nexus 7000 Series devices, you can crea...
Configuring an interface VLAN router's MAC address is not supported. The interface VLAN already has an MAC address assigned by default. The number of VLANs mapped to a VLAN group is not limited by IOS. But if the number of VLANs in ...

priority will become the DR, while the router with the second-highest priority will become the BDR. In case of ties on the priority, we consider the Router ID (the higher the most likely to become DR). Furthermore, if we manually set the priority to zero, that router will never be a...
In Figure 13-5, the Switch is connected to RouterA, RouterB, and the Receiver through GE0/0/1, GE0/0/2, and GE0/0/3, respectively. S1 and S2 are multicast sources provided by different ISPs. You can configure N-to-N multicast VLAN replication based on user VLANs and distinguish ...
On the stub router, no IP routing protocol must be configured. In fact, from the standpoint of ODR, a router is automatically considered to be a stub when no IP routing protocols have been configured. ODR uses the Cisco Discovery Protocol (CDP) to carry minimal routing information between th...
In an effort to accomplish this policy, a VACL named accesspolicy has been created as a test policy for VLAN 101. The router for VLAN 1 is 172.16.101.1 and the subnet is 172.16.101.0/24. The following set of commands define this policy: Cat6K (enable) set security acl ip accesspolicy...
