BGP convegence - Advertisement Interval & others

working on a design with BGP as the datacenter/wan protocol (obviously EIGRP underlay for loopback reachability etc).. 

 BGP will also be used with MPLS and DMVPN overlays

 

have you guys faced any CPU or resource constraints, when lowering bgp default values like:

 

timers 1 3

advertisement interval 1 sec

BFD - neighbor ip address fall-over bfd

PMTU discovery

 

etc .. mainly i want to know if the timers 1 3 and advertisement interval of 1 sec will be OK with regards to constant BGP updates and CPU/memory of the routers...

Your timers update will has a higher hardware requiriments, like cpu and memory.

Thanks Jaderson. 

 

Most of the routers are ISR 4331.. on the core they are nexus 7Ks.. 

 

Do you guys have experience with adjusting these timers ? Is the network stable with these timers ? 

Set for default timers, like keepalives 60 holdtime 180
