Hello, I checked the description of setup "NAT66 DIA With Centralized Data Policy". The link is below. There is a sentence : "To configure NAT66 on the service-side of a device, you configure a NAT66 interface within a service VPN on the device........

Hi, Is it possible to provide the output of 'show ip interface brief' from an SD-WAN router that uses a PIM module with a dual SIM card? I am little bit confused by these statements : Only one SIM is active at a time.SIM switching is handled by the ...

Hello, Please check the attachment for current settings, where Application Probe Class is not enabled yet. I have simple question about BFD. How many BFD packets will be in the output "show sdwan app-route stats summary" TOTAL PACKETS, when I enab...

Hello, I was able to generate FEC between Site 100 & Site 300, in dCloud (Cisco Catalyst SD-WAN 20.14 Foundations Dual DC) I could see FEC statistics on SD-WAN routers with "show sdwan tunnel statistics fec " command. (Site300-cE1.png, Site100-cE1.p...

Hello , We would run dual stack (IPv4 & IPv6) at service side, and also we would run dual stack (IPv4 & IPv6) on the transport internet interface(underlay), on SD-WAN router. Is it possible to enable IPv4DIA (NAT44) and IPv6 DIA (NAT66) via the same...

Hello Dan, thank you for the reply. I checked your output. If you use an "app probe class", then you send fewer BFD packets overall, because BFD packets are sent for each SLA app-probe class separately in a round-robin manner—correct? I'm trying to...

Hi Jonny, Thank you for feedback. Maybe I found out , why I don't see "FEC Loss Recovery Rate" graph on vManage in dCloud. Applications - FEC Recovery is not applicable for C8000v --> This message indicates that the FEC Recovery feature, which is us...

Kanan, thank you for valuable answer. I am wondering, what IPv6 options for DIA solution I have in case I will use the dual stack. We will be in the same situation, in case we will use dual stack, and IPv6 global unicast address from vpn 500 (servic...

Hi Kanan, thank you for update. I am looking for the minimum supported release of Cisco IOS XE and Cisco vManage for DIA feature when I use only IPv6 (global unicast addresses) in the whole network environment. It means. I don't need NAT64, dual st...

It's a pity , there is no IPv6 deployment/ design guide for SD-WAN. There are a lot hidden details in migration from IPv4 to IPv6. There is nobody, who made migration (data plane) from IPv4 to IPv6 (via dual stack) in SD-WAN ?
