Hi Simon,

The hold-timers are not that important, yes, you need to change them, but mainly in very large-scale deployments. More important is to disable the split-horizon and the next-hop-self option.

Check the DMVPN Design guide at
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a008075ea98.pdf

Page 2-18, EIGRP configuration explains it all

Kind regards
Pieter-Jan

Subject: [OSL | CCIE_Security] DMVPN: question about EIGRP holdtime.

Hi,
I used OWLE Lab2 for testing an DMVPN setup. R5 was my hub, R4 and R6
served as spokes. I added an loopback interface to every router, used
EIGRP for routing in the DMVPN.
Without manipulating the holdown timers, I had flipping EIGRP
adjacencies. I'm not 100% sure which holdown timers I have to
manipulate: only the EIGRP, the nhrp or both?

Cheers
Simon
