Can the new GSR actually stay up without crashing for strange reasons,
having weird CEF (Cisco Enragement Feature) bugs, and crashing on vlan
and filter additions or deletions?
The current GSRs with current software versions can't.
Oh, and can the GSRs, new or old, run VRRP with other equipment?
And I'll note that Cisco can only do sampling, just as with the Junipers...
Thanks,
Avi

Please be aware that the GSR new line cards can do predictable full NetFlow and Sampled NetFlow,i.e. enabling NetFlow does not affect the forwarding throughput of the line card what ever feature is enabled.
