The Shadow routers can be connected via different technologies, such as MPLS VRF, tunnels, and 802.1q.
The IP SLA probe can generate some traffics.
Good Luck !
thx dude, and i have anothor question, this one is about traffic generating, i wanna know how can i genarate DNS requests without having a real DNS server, i thought it was possible coz i'v read this in the administrator guide : "IP SLA Manager deploys Cisco IP SLA operations to generate various types of network traffic such as DNS requests, DHCP IP allocation, FTP and HTTP requests......" but it looks like i need to type the IP adress of a existing DNS server.... it dosn't make sens!!! why would i use a real DNS server if i can just simulate various type of network traffic!!???...
I've marked this for the PM to review.
Orion IP SLA Manager will generate a synthetic DNS request from a source device to a DNS server. The purpose of this operation is to measure round trip time for a DNS request to your DNS server. In other words, you would use this operation to ensure your DNS server is operational and performing as expected.
