HSRP

[nevismanuk]

I have 4 routers, 2 are end-to-end data(2mb serial)
the other 2 are end-to-end voice(using IP cards in the PBX,s).
I want to provide each circuit with backup using the other circuit.
I thought that HSRP groups at either ends across both routers and custom queing on access-lists to ensure that both voice and data share equal bandwidth when sharing.
The voice is a 1mb link(serial also).

Would this be the way to go? or is there a more efficient way ?

I'm not sure what your trying to do here, but I don't think that HSRP is what your looking for....

IPCONFIG ??? WHAT???

Ok let's break this down. What i see is this:

-----------Router1---(voice)---Rotuer3----------
--LAN-- --LAN--
-----------Router2---(data)----Rotuer4----------

IF you have IP cards in your pbx I assume your are using VOIP which means your voice packets from PBX to PBX using Router 1 and Router 2 and are normal IP packets..

That being said.

HSPR will NOT load balance but will provide you the redundancy you are looking for. It would be applied to your LAN interfaces on all 4 routers like so.

-------------/Rotuer1--
--LAN--HSRP--
-------------\Router2--

This would be one hsrp group

config would look like this:

Rotuer1

interface fastethernet x/y
description connection to LAN
ip address 1.1.1.2 255.255.255.0
standby 12 ip 1.1.1.1
standby 12 priority 110 preempt <--100 is the default
<--110 will make it active
standby 12 track interface serila0/0 100 <-- this subtracts
<-- 100 from 110
no shut

Rotuer2

interface fastethernet x/y
description connection to LAN
ip adderess 1.1.1.3 255.255.255.0
standby 12 ip 1.1.1.1
standby 12 ip priority 105 preempt
standby 12 track interface serial0/0 100
no shut

-----------------------------------

Rotuer3\-------------
--HSRP--LAN--
Router4/-------------

Rotuter 3

interface fastethernet x/y
description connection to LAN
ip adderess 2.2.2.2 255.255.255.0
standby 12 ip 2.2.2.1
standby 12 ip priority 105 preempt
standby 12 track interface serial0/0 100
no shut

Router 4

interface fastethernet x/y
description connection to LAN
ip adderess 2.2.2.3 255.255.255.0
standby 34 ip 2.2.2.1
standby 34 ip priority 105 preempt
standby 34 track interface serial0/0 100
no shut

Default gateways for all your devices will use the ip address under standby xx ip x.x.x.1
