I have been tasked to make a flat network across our data centers (East coast to West coast) I understand this is a bad ideal. I have two separate EVPL L2 links with two separate ISPs. In the name of redundancy I would like to create a port-channel...

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...

NHM, Got ya! I totally understand that. In that case would ^$ still allow all prefixes? In the case of only allowing my local prefixes wouldn't I need to modify the statement from^$to^(my AS)$ From my understanding ^$ is a wild card allowing all

100% understand the use of ^$ and how ^$ works. I don't understand its use in the configs I listed in my original posting.

Wan_Whisperer · 05-21-2024

NHM,I excluded the prepend config. I understand that "it will send out only the prefix match acl OR match as-path 20" but with it using ^$ it will match everything.Will it not send any advertisement out at all without the match as-path 20?

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?

Wan_Whisperer · 01-19-2023

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