HSRP NOT WORKING...

[Tiago Marques]

Hello,

I have a problem with my "6500 CORE" at the HSRP level

Basically, when I send down the vlan interface of DC1 I quit dripping that network ... from either side the answer is the same = "Request timed out." If I disconnect on DC2, I will not have any problems.

Can you help me?

CONFIG:

DC1

interface Vlan24
description --- Estadio_TS_CLIENT ---
ip address 172.20.24.253 255.255.255.0
standby 24 ip 172.20.24.254
standby 24 priority 150
standby 24 preempt
end

DC2
interface Vlan24
description --- Estadio_TS_CLIENT ---
ip address 172.20.24.252 255.255.255.0
standby 24 ip 172.20.24.254
standby 24 preempt
end

Hi what's the physical connection between theses vlans is it direct or through another switch ?

Did you check the actual physical ports inpath were in FWD mode when the interface was down , usually when HSRP fails and its not a config issue its due to the physical setrup or STP could be blocking a port when it goes down , stoppon the HSRP hello paclets speaking to each other

what did the show standby brief show when you dropped the link were both switches active ?

I leave the HSRP scheme I have mounted.

I'm basically ping the GW 172.20.24.254 from my laptop and the other physical interfaces of each CORE (172.20.24.252 & 172.20.24.253).

When I turn off the vlan interface on DC1,i lose the connection to that network from my laptop... and I get the following output :

DC1

sw_cpd1_core(config)#int vlan 24
sw_cpd1_core(config-if)#sh
sw_cpd1_core(config-if)#
Dec 7 13:08:00 UTC: %HSRP-5-STATECHANGE: Vlan24 Grp 24 state Active -> Init
sw_cpd1_core(config-if)#no sh
sw_cpd1_core(config-if)#

DC2

sw_cpd2_core#
Dec 7 13:08:00 UTC: %HSRP-5-STATECHANGE: Vlan24 Grp 24 state Standby -> Active

but on my laptop i lost connection to the 172.20.24.254!!

duel link the IT switch to the 2nd switch like below physical setup it should work then , trunk or access whatever way the single connection is set to

[Tiago Marques]

Yes it makes sense, because from my pc I go to DC1 and if the vlan interface is down the package is no longer sent to another side ...

see the attachment please.

Yes you need the 2nd link then test again , it should work after that's connected
