HSRP behaviour
Hi experts! I have an HSRP configuration between PC-Linux and 2 routers, and this is the configuration:
ROUTER-1
interface Vlan10
ip address 200.25.192.18 255.255.255.224
standby 110 ip 200.25.192.17
standby 110 timers msec 300 1
standby 110 preempt
ROUTER-2
interface Vlan10
ip address 200.25.192.19 255.255.255.224
standby 110 ip 200.25.192.17
standby 110 timers msec 300 1
standby 110 priority 200
standby 110 preempt

So, ROUTER-2 is "active" and ROUTER-1 is "standby". Also, I have a Port Channel between these 2 routers. In normal conditions everything is working fine:
- ROUTER1 is power-on, ROUTER2 link is power-on, the traffic is going through ROUTER2.
- ROUTER1 is power-OFF, ROUTER2 is power-on, the traffic is going through ROUTER2.
- ROUTER1 is power-on, ROUTER2 is power-OFF, the traffic is going through ROUTER1.
But I am not sure about the behaviour when the router is power-on but it has a 100% of CPU Process. Normally, the HSRP is verifying the interfaces and when the process is high the interfaces are still up. I have some doubts about HSRP:
1.- When ROUTER2 (active) is with 100% CPU Process, does the traffic must siwtch to ROUTER1?
2.- Does PC-Linux know if ROUTER2 is totally down even when it has 100% CPU Process?
3.- Does HSRP work if the router is power-off of it has a 100% process?
Thanks guys!
