What It Means The beginning of the log shows that keepalives are not being responded to and the
state of the Routing Engine changed from
master to giveup after the request chassis
routing-engine master release
command was issued. However, the other Routing
Engine is not taking over mastership because it is unreachable. Eventually a timeout
(
E_TMOUT) occurs until the Routing Engine reaches the maximum number of
attempts permitted (
E_MAXTRY). The output then shows the Routing Engine state
changing from
giveup back to master.
The output doesn’t indicate why the mastership switchover did not work. However,
it is clear that the backup Routing Engine is unreachable.
