We'd like to change the default OSPF timers from the default 10/40 to something more aggressive, like 1/4.
All the routing devices are 3560's on a fiber ring, running 1 Gbps, so we figure it's safe to do so.
Is there a global command to change the timers, or do I have to do it on every interface, even the ones that are put in passive-interface? (ip ospf hello-interval 1)
Also do we need to change it on all the routers/L3 switches in the same area, or can some of them keep the default?
Four of the 3560's will peer w/ CE routers that are managed by our ISP, and they don't want to change the timers...
I saw a similar thread below, but thought I'd start a new one.
