6509-E w/ Dual Sup-720
2 Line Cards - 6748s w/ DFC installed
Assume that the CEF tables are synchronized between the DFC and the Supervisors and that NSF and SSO are both enabled.
Question: Both Supervisors Fail - How long could the DFC CEF tables continue to forward traffic before being invalidated? Layer 3 traffic? Layer 2 Traffic?
Since there is no supervisor involved here, what about MAC/CEF aging? Would it take place on the DFCs or would they just keep their caches indefinately until the control plane returned to operation?
