Can you ping 10.5.2.90 from Mumbai router by using a source as 10.5.2.2?

If not,please add the following commands.

MumBai

ip route 10.5.2.88 255.255.255.252 10.5.2.1

Just want more information to help you to use IPSLA to solve this issue. The problem is that they are not point-to-point then we have to uninstall the static route on both site at the same time.

Re: Require Help in IP SLA

Hi Toshi....Thanx a lot

I am able to ping both the ips.Pls tell me whether the metric configured is correct or not? (For VSNL Link).I configured IP SLA for only one link,Is it require to configured for second link also?

I think in IP SLA, route map is require.Can you tell me the config for the same.

Your Help is appreciated.....!

Re: Require Help in IP SLA

arjun,

I haven't seen the whole configuration but you said that you have full connectivity. Well, Assuming that REL link is primary. Based on the existing configuration.

- If IPSLA of both sides are telling you as OKAY then both routers will install a static route using REL as a media (AD=10).

- If IPSLA of both sides are telling you as NOT-OKAY then both routers will install a static route using VSNL as a media(AD=100).

Is it possible to see IPSLA of one side says good and another one says bad? hmmm... Hope not to see.

EDIT: Why don't you use a dynamic routing protocol? I'm curious.

HTH,
