Hi,

I'm running HSRP in a small LAN.... I am using two 800 series which are connected to a 2960Switch... the configuration in the routers is as per below....

For Router-2:
interface Ethernet0
ip address 192.168.0.3 255.255.255.0
standby 1 ip 192.168.0.4
standby 1 priority 200
standby 1 preempt
hold-queue 100 out

For Router-1:
interface Ethernet0
ip address 192.168.0.3 255.255.255.0
standby 1 ip 192.168.0.4
standby 1 priority 101
standby 1 preempt
hold-queue 100 out


The HSRP seems to be working, i.e. for Router-1, the State is Standby and for Router-2, the State is Active.

I also have a laptop connected to the 2960Switch with IP address 192.168.0.1, default-gateway 192.168.0.4 (the virtual address)

Now my problem.......when I ping from the laptop to the virtual address I get a 50%-75% lost every time......and the same happens when I ping from the router to the laptop.......

Any ideas as of why I dont get a 0% loss????

Thank you for any help
 
Hi
For router 1, change your physical interface address to 192.168.0.5 255.255.255.0 or any other unused address in that /24 network range

Cheers

Hi,

sorry that was a typo mistake......a copied and pasted...

I was already using 192.168.0.2 on the Ethernet interface for Router-1
 
Hi,
do you have the same problem pinging the physical addresses of the routers?

Have you check the speed/duplex configuration of the routers and the switch ports where they are connected to?

 
Do you get a kind of symmetrical packet loss or complete random.

i.e. are you losing the 1st packet, 2nd always pings, 3rd is always lost, 4th always pings etc etc or is the packet loss not to predicatable?
