The least-significant bits of the Bridge Priority are the ones repurposed for the extended system ID. Therefore, you can configure bridge priority to 32768, but you can't actually make it 32769! The precision is no longer increments of 1 but in fact the increments are 4096. Here's an old post on this topic with some graphics that may help: Spanning tree ...

Power Cycle Devices The Power Cycle Devices button on the Realtime Bar allows you to power-cycle all of the devices in your network. Pressing it turns all devices off and then turns them back on. Pressing this button will also clear all events if you are running a simulation with the network. The Power Cycle Devices button is also available in Simulation ...

What you want to do will not work the way you envision. You cannot have overlapping networks separated by layer-3 without an ugly workaround, e.g. NAT. The problem with that is NAT will break OSPF, among other things. To use the same network and OSPF, you would need to bridge the two sites at layer-2, and that can cause other problems, such as creating ...

What issue(s) are you trying to fix? Bootloader and "BOOTROM" (aka. ROMMON) are different things. (basically, the difference between GRUB and BIOS on a PC.) I don't see an updated ROMMON available from Cisco. And that wouldn't replace the "ROM" based ROMMON, but loads into the "upgrade ROMMON" area.[*] (I have upgraded ROMMON by ...

Assuming you want use VLAN 3 & VLAN 4 as your LAN network and want to configure pat natting for internet access, and assuming VLAN 1 is used for DMZ network for hosting an application which needs static NAT.

The requirement for OpenVPN connections is the biggest constraint. Yes, you should be able to do all that using one Linux box. You'll want to configure multiple routing tables, or use ip route 2 source-routing features, to help you achieve the desired behavior. I think the Super User section of Stack Overflow will be a better place for a detailed ...

Isn't it automatically launching a terminal when connecting to it over serial console cable ? Answer : no. Simply need to reboot the router (eg power off and on), so it begins sending serial stuff to console port.

Here to establish connectivity the main challenge you are facing is cable limitation right ? To overcome this issue use media convertors connecting ethernet cat cable to SG350 switch to media convertor and optical fiber connecting another media convertor placed in another building and same this media convertor will connect to ethernet cable cat to SG350 ...

Think of a VLAN as a virtual switch. Devices on different VLANs (virtual switches) share no common (data link layer) network, so they cannot communicate directly. A router connects different networks with each other, so attaching a router in between both VLANs and configuring the routing enables nodes to talk to each other across those VLANs. Configuring the ...

By default, different VLANs won't communicate with each other. You can make them communicate by inter-VLAN routing. For this requirement, you require one router and one switch. Instead of this, you can create layer 2 same vlans in switch and allocate both printers to the same vlan. In the switch, configure both ports on vlan 1 so that both printers can talk.....

NX-OS 7.x likely does not support BFD BGP Multihop BFD BGP multihop support was introduced in NX-OS 8.1(1) according to the NX-OS 7K Command Guide.

Please refer the link for configuration of subinterface or router on stick configuration on fortigate firewall https://youtu.be/bIeQyQKptRc If your using fortigate firewall as core or perimeter devices and Cisco SG300 as distribution switch in your setup then you can accomplish this task by creating sub interface on fortigate firewall Configure SG300 switch ...

The Fortigate requires routes to the networks behind the SG 350. (Make sure routing has been activated on the 350, but I think it's by default.) Since the 350 doesn't seem to support any routing protocol you'll need to set up static routes on the Fortigate. In the GUI, static routes are in Network -> Static Routes. If you're not using those addresses ...

We can implement this network topology with single router and single switch (layer 2 switch ) In router configuration Router(config)# int ethernet gigabit 0/1 # ip address 204.10.83.1 255.255 .255.0 #no shutdown Router(config)# int ethernet gigabit 1/1 #no ip address #no shutdown Router(config)#int ethernet gigabit 1/1.10 # encapsulation dot1q 10 # ip ...

For example Router(config)# ip DHCP pool vlan10 Router(dhcp-config)# network 192 .168.1.0 255.255.255.0 This command is mentioned beacuse desktops in vlan10 will get ip allocation from this pool of ip network.. Vlan 10 allocated desktop will get DHCP ip range from 192.168.1.1-192.168.1.255 dynamically.

Router will automatically know which interface is associated with which DHCP Pool. You create a network for the pool, exclude the addresses like static hosts or reserved addresses, provide default gateway and DNS servers (you can edit few different DHCP options if needed). Based on default gateway and the network, router associates it with either the ...

No need to create sub interface with public ip . You need to assign public ip for outside interface of router . Ànd do natting nat overload Router(config) # access-list 1 permit ip 10.0.0.0 any IP NAT inside source list 1 interface "router outside interface" overload IP route 0.0.0.0 0.0.0.0 point towards gateway of ISP

There needs to be a few assumptions in place in the red area - A-R2 and B-R2 need to have some kind of upstream static route to A-R1 and B-R1 respectively. This would most likely be a default route. A-R1 and B-R1 will need static routes pointing back to A-R2 and B-R2 respectively for their specific routes (ex: A-R1 would have routes to 192.168.1.0/24 and ...

If the R2's aren't running a routing protocol with the R1's, the only way to know what's beyond them is via statics. And that's not exactly "scalable", but since you don't control them, you can't trust what they might advertise anyway. (i.e. even running a dynamic protocol, you'll have to explicitly configure a list of allowed prefixes.) (Hint: the ...

The easiest way to accomplish your plan is to: Create a VPN connection over the FTTC connections. Create a second VPN connection over the E-band connections. Set up your internal routes through both VPN tunnels. Use a lower metric (=higher priority) on the desired VPN link. That way, the lower metric causes the routes over E-band VPN to be used normally. ...

The ip nat inside & ip nat outside is mentioned on interfaces because the layer 3 or router don't know which interface is consider to be inside and which interface is consider to outside . Thats the reason we are telling router clearly by assigning Int ethernet 1/1 Ip nat inside No shutdown Int ethernet 1/2 Ip nat outside No shutdown If we mention ...

With it being enabled only for an internal lookup, it must have a rather limited usefulness. What is the purpose of this feature then? The idea is that when the router (i.e., using the management plane) does a DNS query, it will rotate the server used, presumably for redundancy. Typically, Cisco will add features if requested by big clients. I imagine this ...

Sorry for being blunt but if you can't answer that you should reconsider applying for that position. When asked such a question you should counter with "what are the requirements?" - how redundant, resilient, fast, future-proof does the network need to be? Are there hot spots (data center, power users)? Is there a budget? The usual structure is to ...

So you are getting default from both circuits and you want traffic from certain subnets to use a specific circuit to send traffic out? Assuming the traffic hits the right border it will use the circuit connected to it because eBGP trumps ibgp for the same prefix. This means your routing decision is at the cores not the borders so make sure the link from core ...
