Saku,
You are correct, they have. To many things to tshoot. I aways try to
keep my configuration simple and clean. Things have to be more fast, reliable,
available, 200% uptime, with no downtime with a good price.
This is a part of a QFX5110 protocol configuration, it represents a part of a
100Gbps P ring of QFX5110 in a specific area collecting all traffic that’s will
jump to another city. The rest of configuration are system login access and
filters
set protocols rsvp interface et-0/0/30.0 bandwidth 100g

All these protocols have hello timers, LDP, ISIS, RSVP, BGP. And each of them
you'd like to configure to trigger from events without delay when possible,
instead of relying on timers. Indeed you can have BGP next-hop invalidated the
moment IGP informs it, allowing rapid convergence.
