Hi All, I have cisco 3845 Router on that two ISP link is terminated (one is TATA having 100 Mbps and second is Airtel having 10 Mbps) we want to use TATA as primary and Airtel as a backup means if TATA fail, Airtel should work and there is BGP configuration is done. The problem is that when i test the bandwidth by speedtest i am getting uploading speed above 80 Mbps and downloading only 10 Mbps and i observed that is asymmetric routing. Pls help to me resolve this problem.below is the BGP configuration. ! interface GigabitEthernet0/0 description Airtel_ISP_Link ip address 184.108.40.206 255.255.255.252 ip accounting output-packets ip flow ingress duplex auto speed auto media-type rj45 ! interface GigabitEthernet0/1 description "TATA link" ip address 220.127.116.11 255.255.255.252 ip flow ingress ip flow egress ip virtual-reassembly in duplex auto speed auto media-type rj45 !
