hsrp troubleshooting document

Hi,

Can any one provide some trouble shooting documents and links :

I have a config like in router 1 and router 2

standby 2 ip 10.x.x.x

standby 2 priority 110

standby 2 preempt

standby 2 track 2

standby 2 track 3

ip sla monitor 10

type dns target-addr x.x.x.x name-server x.x.x.4

ip sla monitor schedule 10 life forever start-time now

!

track 2 rtr 10

!

track 3 rtr 10 reachability

It is a failover scenerio.

Say when router 1 fails router 2 does not take over .

What are the troubleshooting steps that I need to follow .

Thanks in advance

Raj

Hi Raj ,

Track rtr command is used for tracking the state of a Cisco IOS IP Service Level Agreements (SLAs) operation , not the router.

Every IP SLAs operation maintains an operation return-code value. This return code is interpreted by the tracking process. The return code may return OK, OverThreshold, and several other return codes. Different operations may have different return-code values, so only values common to all operation types are used.

Two aspects of an IP SLAs operation can be tracked: state and reachability. The difference between these aspects relates to the acceptance of the OverThreshold return code. Table 62 shows the state and reachability aspects of IP SLAs operations that can be tracked.

Table 62 Comparison of State and Reachability Operations

Tracking Return Code Track State

State OK Up

(all other return codes) Down

Reachability OK or over threshold Up

(all other return codes) Down

Examples

The following example shows how to configure the tracking process to track the state of IP SLAs operation 2:

track 1 rtr 2 state

The following example shows how to configure the tracking process to track the reachability of IP SLAs operation 3:

track 2 rtr 3 reachability

Hi Raj ,

The config on your router is for SLA tarcking purpose , not for tarcking interfaces.

Below link may be useful for you.
