I have found lots of great recommendationsfor tuning CAMPUS OSPF networks (assuming 1Gig & 10Gig links) in the document http://www.cisco.com/en/US/docs/nsite/campus/ha_campus_routed_access_cvd_ag.pdf. For those who haven't read this document it boils down to:
Cisco recommended values for Campus OSPF network design:
router ospf 1
timers throttle spf 10 100 5000 !based on 10ms debounce timer for 1Gb/s & 10Gb/s Ethernet
timers throttle lsa all 10 100 5000
timers lsa arrival 80
ip ospf dead-interval minimal hello multiplier 4
But what about WAN links?
Does anyone know Cisco's recommended values for Hello/Router Dead intervals for WAN (Frame Relay/PPP)?
And is it worth tuning spf & lsa timers on WAN links?
A reference to an official Cisco document would even be better.
