FTD Default EIGRP Hello / Hold Timers

Hi, 

 

I noticed the default hello/hold timers on FTD (Cisco FTD 4110 6.3) are 60/180 seconds, although the link speed is more than T1 speed - link is 20 Gbps. The other end of my FTD is a Catalyst 9500 with default timers of 5/15 seconds. I can change the FTD timers through FlexConfig. Need to understand why the defaults on FTD are higher and Is it a Cisco recommendation to keep timers higher on the FTD (and potentially match at the other end as well)?

Re: FTD Default EIGRP Hello / Hold Timers

Hi Rick,

 

You'll most likely get a definitive answer from Cisco only but from my experience it's set due to stability. I wouldn't use as a typical router.
