I am modifying an existing network work design to allow full IP redundancy across two networks using HSRP.Ideally, I would not trunk VLANs across two data centers I would implement VXLAN to limit the broadcast domain. Take a look at my diagram. I ha...

Network has been stable for years Two routers using HSRP routing on a stick connected to a switchMany subinterfaces but all of the sudden some EIGRP vlans are flapping. Looking at "show ip eigrp neighbors" the SRTT times are way different. Is that ...

Project ideal from the bossI have two data centers connected via a dedicated transport L3 link. Each data center has it own core routing and switching devices and unique vlans.The goal would be to be able to have a hybird flat network and have the a...

What is acceptable interface saturation/utilization before an upgrade is needed?The interface from my core router to my core switch is hitting about 50% utilization consistently. In the past, it was around 65% and I did not notice any issues. When do...

From what I read about Evpn/vxlan and xconnect/pseudowire they both great ideas for a flat vlan network. The major issue I am having is the routing. Is it possible to have the same default gateway at each data center?

I posted my diagram of one DC they are both exactly the same. LMK if you need anything else.

Paul, Because you got it working with my configs I am just going to assume it's related to GNS3. I will test the configs on my real environment in a few weeks.Thanks,WW

No, the port channel on the Routers and not building : R1# show etherchannel 1 summaryFlags: D - down P - in port-channel I - stand-alone s - suspended R - Layer3 S - Layer2 U - in useGroup Port-channel Ports

After running the command show etherchannel sum on the router it looks like port-Channel 1 is not building. I ran debug etherchanel ***see results at the bottom of this post.*** R1#sho ip int bInterface IP-Address OK? Method S...
