Re: CEF EPOCH

Hi mate.

As per Cisco Express Forwarding title of CiscoPress, chapter 2:

The CEF Epoch
The FIB and adjacency tables have a concept of a global version,
referred to as the epoch.
Entries added or modified have their epoch number set to the table's
epoch number. Epoch
numbers occupy a byte and range from 0-255, and their primary use is for
high availability
in large-scale networks. During a switchover, the CEF tables have their
global epoch
number incremented. The entries are then updated from converging routing
protocols ...
