I have a phase 2 DMVPN network with approx 40 spoke routers and dual hub routers. 90% of this is working very well. However I have 3 or 4 spoke routers that are unable to communicate with each other directly (traffic goes via the hub router between these specific sites) however they are able to coomunicate directly with the other 35 or so routers. I think this is an NHRP issue as when I do show ip nhrp detail on one of these 4 routers, the other 3 routers display a (no socket) entry. I am able to clear this "sometimes" by clear ip nhrp. Whenever the (no scoket) entry is there spoke to spoke communication does not work. Any help would be greatly appreciated.
