First, the network layout for this OTV network. As you can see in the diagram, the ASR routers are back-to-back connected. There is no guideline how to connect these routers, as long as there is IP connectivity between them with multicast capabilities and a MTU of atleast btyes.

You cannot get OTV working with a one-interface configuration. The interface configuration is pretty basic. In our configuration, multicast is being used for MAC advertisements. Your WAN network has to be multicast enabled. Another important configuration step is to change the MTU. OTV uses a header of 42 bytes, which means that the WAN network has to carry packets of at least bytes.

This VLAN is unique per-site and can not be stretched to other datacenters! The site-identifier is a unique ID for a site aka. This is another configuration difference with the Nexus the service instance. In our case, VLAN 10,20,30,40,50,60 are stretched between the datacenters. The get a required layer 2 connection to the datacenter LAN, we need to configure service instances on the LAN facing interface. Note: you cannot share this interface with the WAN join interface!

This is the OTV configuration. To verify the OTV configuration, use the following commands: Show otv. In the config I used for this blog, the ASR routers are back to back connected. All you need for connecting the ASR routers is a layer 3 connection. You can use dark fibers, mpls, some ISP layer 2 or 3 wan, as long as you have a connection with at least a mtu of Great article though. Hi Ryan, Great question, you had me thinking for a few minutes! Great blog Rob.

I am a bit confuse on the otv site bridge-domain and would really appreciate if you can clear up my confusion. I know you mention not to extend these Vlans. Thanks Rob. Thanks for clarifying that. My other question if I may.

Because of the fact that OTV has to learn and advertise the movement of the MAC address, a vmotion between datacenters can result in a downtime of a few seconds.

Great start, thanks, but what pussels me. Any suggestions or alternatives? Or where should I raise the case? But, if 1 ASR router failes, you only have 1 dark fiber active. So, there is less redundancy if you use this scenario. That is possible to do!HSRP, as well as Virtual Route Redundancy Protocol VRRP are considered high-availability network services that allow for almost immediate fail over to a secondary interface when the primary interface becomes unavailable.

That primary will handle all routing requests while the other routers within the HSRP group simply wait in a standby state. These standby routers remain ready to take on all of the traffic load if the primary router becomes unavailable. In this scenario, HSRP provides high network availability since it routes IP traffic without depending on a single router.

For this scenario we will use the topology shown below:. It consists of just two routers R1 and R2 acting as the default gateway for the Only one of these routers will be active at a particular time with a virtual IP address of These means that all devices on the PC1 will be configured with this virtual IP address. This group number can be any number between 0 and HSRP version 1 and the only requirement is that you must use the same number across devices in the same HSRP group.

We can use the show standby command to see the status of our HSRP configuration. Ideally, with the same priority, the router with the highest IP address will be elected the active router. However, I configured R1 first and it became active before R2 came on board. Since R2 has the same priority as R1, R2 will not become active even though it has a higher IP address We will talk about priority and preemption later in this article.

We will perform a traceroute to 8. Note : When replying traceroute, the IP address of the physical interface is used, not the virtual IP address. Check this link for more information. Notice how the traffic flows through R2 I decided to take a little detour to talk about routing when HSRP is configured.

There are a couple of things to note:.

For example, what if we wanted R1 to be the Active router instead of R2? To force a particular router to be the active router in an HSRP group you will need to use the priority command.I have divided this article into three parts i. I want to make it clear that this cisco configuration tutorial is for cisco learners. In basic Cisco router configurations, we will review all basic steps for configuration of a router and then see all basic Cisco CLI commands.

In Order to configure a cisco router you need to access the router CLI interface. You can do this in numerous ways. Here I am show you the most basic way to access a cisco router that is access Cisco router through console cable. Most for configuring a brand new router you need to adopt this method.

Old console connection came with the DB-9 to console connection. But now a USB console connections are being used in market. You see this connection in following figure and you can connect it according to this. Once your connection setting is complete, you are required a software for access the router CLI. Putty is the most famous and easy to use software. You can download it free from internet. Open the putty and give the same serial line as you find in device manage and click connect. You can use any other software for creating a connection to router.

Once you have a physical connection with your Cisco Router, you can configure it. Before Going into configurations of Cisco Router, let introduce you the basic configuration modes of Cisco. There are 3 modes or command-levels in Cisco router.

In each command mode you have specific privileges and control. In first command mode of cisco you can run limited type of show commands, basic reachability tests. In this mode you can have access to all monitoring commands of router. The Global configuration mode is for administrator where you can configure your Cisco router and the running configuration. For more Cisco Global configuration mode Commands you can visit here.

Once your cisco router is boot up you can check already performed configuration or default configuration Using command show running-config. If you are new to cisco just run this command in privileged mode this will give you a brief of all physical interfaces of cisco routers as well as all the protocols configuration.

You can set different types of password on each command level mode, which will make your router secure. The most basic password that you can configure on cisco router is to set the console password. This password blocks the unauthorized access through console cable on Cisco router. You can set the console password by using the following commands.Documentation and Resources.

Participate in the Technical Documentation Ideas forum at:. This section contains information about the tools and parts, warnings, site preparation information, and other information for the rack-mount installation and equipment shelf or tabletop installation. Warning Only trained and qualified personnel should install, replace, or service this equipment.

Statement For an equipment shelf installation or tabletop installation, verify the following before installing the router:.

Before you begin the rack-mounting tasks, decide whether or not you want to attach cable-management brackets to your chassis. Note If you install cable-management brackets, ensure that you use the rack-mount ear holes specified in the procedure described in and install the brackets after the chassis is mounted on the equipment rack.

This section provides information about rack-mounting the router. To attach the rack-mount brackets on a Cisco ASR X Router for a front rack-mount configuration, follow these steps:. Step 1 Locate the threaded holes in the front sides of the chassis. Step 2 Align the rack-mount bracket to the side of the router. Step 3 Position the front rack-mount bracket's top hole with the chassis, first top hole behind the side vent holes, as shown in Figure 1.

Step 4 Insert and tighten the black screws on one side. Step 5 Repeat Step 1 through Step 4 on the other side of the chassis. Use black screws to secure the rack-mount brackets to the chassis.

Note Ensure that you attach the cable-management brackets to the chassis after you install the chassis in an equipment rack. Step 1 Position the chassis such that the front is closest to you and lift it carefully into the rack. To prevent injury, avoid any sudden twists or moves.

Step 2 Slide the chassis into the rack, pushing it back until the rack-mount brackets meet the mounting strips or posts on both sides of the rack. Step 3 Position the chassis until the rack-mounting ears are flush against the mounting rails on the rack. Tip To provide enough space to attach the cable-management brackets to the chassis in the rack easily, ensure that you use the rack-mount bracket ear holes specified in Step 4. Step 4 Hold the chassis in position against the mounting rails and perform these steps:.

Insert the bottom screw into the fifth hole from the top of the rack-mount ear, and use a hand-held screwdriver to tighten the screw to the rack rail. Insert the top screw into the second hole from the top of the rack-mount bracket ear hole diagonally from the bottom screw, and tighten the screw to the rack rail.
