Hello,
We currently have a data center connected to a single ISP (ISP xyz). We have a single internet edge router which connects to the ISP using BGP.
We plan to have a tenant share our internet link but have their own internet edge router. The de...
Hello, all and @Royalty
We currently have two Data Centers. Each data center has a 100Gbps Internet connection. We have a Cisco ASR1001 edge router which connects to a core switch on the LAN side.
I am considering two SD-WAN design options for th...
Hello,
We have a new site where we are planning on installing brand new WAP units (CW9166I-B) and C9800 WLC. This is a green field deployment. Our wireless vendor is telling us that the CW9166I-B units are Meraki Cloud and not Cisco when you first i...
Hello,
According to this link: https://learningnetwork.cisco.com/s/article/cisco-sd-wan-vpn-segmentation, the number of Service VPNs that can be assigned on the WAN Edge router is 64 (subtracting VPN 0 and VPN 512 = 62); however, that number is high...
Hello,
The company I work for is considering implementing Cisco SD-WAN and one of the design questions that came up was "could we leverage the existing Internet circuit (public Internet as the transport), use the exiting Internet edge router, and pu...
Thanks for the feedback!
Actually, we have 2 DCs. Each DC represents a hub. We use the same ISP at both DCs for the Internet access. This is a hub-spoke design where the spokes will prefer one sending traffic to one hub (DC1) over another (DC2). In t...

--- ZK: WAN Interface: I will assign the WAN IP address that's currently assigned to the existing internet edge router to the WAN interface on the new switch. This interface will link directly to the ISP
"It usually takes a very c...
@balaji.bandi ... Thanks for the feedback.
Would we need to use eBGP on the WAN side (transport VPN) of each cEdge at each DC or static routing would work fine? If we go with the static routing at each Hub, we could use centralized policies to choos...
@Richard Burts ...
1- "I am assuming that the switch will operate as a layer 3 switch forwarding traffic between the ISP on one interface and your router and the tenant router on a second interface. Is this your intention? ZK ----- Correct

Thank you all for the helpful feedback.
I attached a simple drawing to show the current topology in a simple setup and my proposed design.
@Joseph W. Doherty ... you are correct. ISPs provide two sets of public IPv4 blocks:
- A /30 WAN block and a /2...
