Hi Prashant,

Your picture is not clear to me. However based on best pratices, I assume you would be having two WAN circuits.

Based on above scenario, you would be tracking ( with help of ip sla) your primary circuit. And if that primary goes down, then you track will go down and HSRP which is using your same track will shift traffic to your secondary link.

is sla monitor necessary

on active router only one wan link is terminated.

BGP is configured with hsrp.

on standy router router there is also one wan link

bgp is configured with hssrp.

my outgoing traffic is going through active  router and incoming  is comming through standy router.

As sla is configured for wan link . if wan link on active fails than neighour ship with active router and

isp goes down  as bgp is configured and traffic will now be going out through by link on standy router .

so is thereneed of sla monitor ? as bgp is taking care?

Hello Prashant,

I have responded to you on your other post on configuration of BGP.

Hi Prashant,

As I mentioned earlier, track will be used to identify outage on your primary link on Active router. If it goes down, HSRP priority will be decremented and your Standby router will become Active router.

Yes, it is absolutely required...

HTH,
