IP SLA Query PT 3

Hello Community,

I'm testing ciscos IP SLA ICMP-Echo between two GNS3 routers. Everything is configured corrected (I think). When I test the sla by shutting down the interface between the two routers I still see successes (see below).

Is this because I'm using GNS routers?

R1#show ip sla monitor statistics 1

Round trip time (RTT)   Index 1

        Latest RTT: 8 ms

Latest operation start time: *00:25:27.055 UTC Fri Mar 1 2002

Latest operation return code: OK

Number of successes: 12

Number of failures: 0

Operation time to live: Forever

The configuration is as follows:

R1#show ip sla monitor configuration 1

IP SLA Monitor, Infrastructure Engine-II.

Entry number: 1

Tag: gns_echo_test

Type of operation to perform: echo

Target address: 192.168.1.2

Life (seconds): Forever

Entry Ageout (seconds): never

Recurring (Starting Everyday): FALSE

Status of entry (SNMP RowStatus): Active

Your help will be greatly appreciated.

Cheers

When you shut the interface between them, using the extended ping, can you ping as following :

Target address: 192.168.1.2

Source address: 192.168.1.1

if yes, it should show succesful.

-Thanks

Vinod,

My apologies, I don't think I made myself clear.

I'm suggesting that with the interfaces shut down between the two routers I'm still seeing successes when I should see failures
