Hi All,
There is a DSL backup link in our WAN environment. whenever Primary link goes down , Routers are NOT learnt from Backup link. it required eigrp reset at DMVPN Hub router.
have you ever facing such kind of issues.. please let me know what factors to be checked...
Router ID got changed recently ..that I know....
Thanks

Hello
You dont say how your topology is setup for Dwvpn.
Is it a dual or single hub and spoke design?
Can you post (if applicable) your hub and possibly one of the spoke routers running config?

Which side switchovers to DSL backup, HUB or Spoke?

Switchover happens at Spoke end.

Put the following command under spoke's tunnel config.
