No, i cannot ping the loopbacks…when they are shut down.

Hope you are doing good.

I tried to monitor two WAN loopback IPs using 2 tracked objects X and Y from a WAN router.

But when the loopbacks were shut, the tracked objest X and Y were still showing UP…

Any ideas ?

You are right that you would need a second object for the secondary link. Using the same one would remove both routes; that’s pretty pointless, eh? :) If you want to get HSRP involved, you can have a third object to decrement HSRP priorities on the router. You can probably use objects 1 or 2 to track HSRP, as well, though; it all depends on what you’re tracking and how you want the traffic to behave.

To track primary default route, we are creating an object1, mapping it with primaruy default route and tracking it so what when it goes down primary default route is removed and backup default route starts routing traffic.

But what if backup route is UP but traffic is not being sent out due to some other reason,say, some link down in the service provider’s internal network, and now both the primary and backup links are not able to send traffic out.

Shouldn’t there be another tracked object2 mapped to backup route also, so that when object2 fails backup route is also removed from routing table and with tracking of backup interface using HSRP, HSRP failsover to the standby router.

In this setup, the router only has a single default route, so only one link is used outbound at a time. If you want to do any type of load balancing outbound, you could have equal-cost default routes with track object that pointed out each provider. If one track object fails, the other link would be used for all traffic until the object recovers. I’m simplifying it, though; there are other things to consider such as per-packet balancing and the return traffic patterns.

When the 2nd default route becomes the active route after the primary link fails,if the primary link comes up, will the 2nd default route become sort of passive and would all traffic be going out via the primary link again automatically ?

What cmd does this ?

We have the following setup between 2 redundant sites, Site1(primary) and Site2(Standby)

-RTR1—ISP1A
| Old Scenario
LAN
|-RTR2—ISP1B
——————————–
—ISP1A1
-RTR1
| —ISP1A2
| New Scenario
LAN —ISP1B2
|-RTR2
—ISP1B1

In the old scenario, we have 1 default route on RTR1 and RTR2 pointing to ISP1A and ISP1B for each link. Now in the new scenario, service provider is proposing to attach a new link at each site as seen above.

In the new scenario, i want to use IP SLA monitor to track primary default route to ISP1A1 and weigh backup default route so that it takes over when primary fails.

Plz , confirm if this is as per one of ur articles on Reliable Static Routing.
