Redundant Link Configuration Without BGP

Hello Friends!!!



Again Comeback with something new!!
Here We performing some redundant link configuration with Help of HSRP, IPSLA, Track Reach ability Features.

In that Scenario We have two ISP link or lease line, At a time BSNL is primary active link, if BSNL link failure than our whole traffic automatically routed to AIRTEL Lease line without effecting whole network of Customer.

In that we have no access of BSNL or AIRTEL. We are used only CPE router.
See Configuration carefully...
