HI all,
Assuming that configured the HSRP and STP on the active and standby
distribution switches.
In case of HSRP, we can use the preemt option to return to the original
primary switch once the primary switch recovered. That is, without the
preemp option, secondary switch keeps active continually after the
primary fails.
Wondering how about the STP.
I configured the PVST+ between Cat6500 and Cat4000 switches.
If the root bridge fails, secondary root bridge will take over to active.
And then, what happen after the original primary swith recovered. I
understand the original primary switch will regain the root bridge. That
is, it will bring sencond outage as the HSRP preempt option do. Then how
can configure the switch so the secondary root bridge keeps the active
though the original primary returned.
TIA,
Paul.
