IWAN command dynamic-path

Hi all,

I'm implementing IWAN solution.

On the latest Cisco Validated Design, the "domain XXX dynamic-path" is configured on Spoke routers tunnel interfaces. On the Hubs routers, the "domain xxx path ISP path-id id" is implemented and documented.

 

Unfortunately, I haven't find any documentation about the "domain XXX dynamic-path"command.

 

Can someone explain me this command ?

 

Regards,

Hugo

How Site Prefix is Learnt?

 

Master controller learns about a new prefix added or removed in the RIB table from the border device.

On a branch site, when the WAN interfaces are configured using the domaindomain-name dynamic-path command., the wan interface details are shared with the master controller by all border routers in a site. The master controller classifies this prefix information as WAN or LAN prefix, as appropriate.

On a hub site, The prefixes are learnt and classified similar to a branch site. The only difference is the command used to configure the WAN interface, which is domain path service-provider-name path-id number command.

It is mandatory to configure prefixes on the hub and the transit hub. It is also mandatory to configure the domain domain-name dynamic-path in branch tunnel interface.
