[c-nsp] NHRP and DMVPN problems

[Pablo's Gmail]

You may need to move off this IOS train. Look under IP Routing Protocols -
there are some NHRP related items.

My only experience with PC bus error loops were hardware related. These were
resolved thru sequenced removal of modules and memory while reloading the
router each time.

Hope that helps
