Cisco Load Balancing with Failover setup example. There is Cisco router of 7. Fast. Ethernet interfaces FE and 2 serial ports. It should act as load balancer and failover for LAN connected to it via one FE 10 interface while two identical Internet connections are going to FE 00 and FE 01 lets name these connections as ISP1 and ISP2. No dynamic routing protocols are used by ISPs but only static routing. Dual Audio Hindi English Movie Site'>1992 Dual Audio Hindi English Movie Site. The primary task is to ensure quick failover between two Internet connections so LAN users are automatically switched to ISP2 if ISP1 fails and vice versa. When both ISP1 and ISP2 are online the traffic of LAN users should be shared between two links to double available bandwidth on uplink Tx and downlink Rx, in other words the router should be configured for load balancing between the links. You can see a network diagram below Load balancing setup description. There are two basic options available per destination or per packet load balancing. Since ISP1 and ISP2 connections have almost the same link characteristics including delay, jitter and bandwidth, it is reasonable idea to pick per packet option. In comparison to per destination load balancing approach per packet uses more routers hardware resources but makes it possible to share traffic between connections more evenly. For better forwarding performance the router will be configured for Cisco Express Forwarding or simply CEF per packet load balancing. PNG' alt='Zabbix Log File Monitoring Example' title='Zabbix Log File Monitoring Example' />Failover description. Every 3. 0 seconds the router will ping two IP addresses through ISP1 and two other IP addresses via ISP2. If both IPs via ISP1 becomes unreachable we assume that ISP1 connection fails in this case the router will delete ISP1s route from its routing table so ISP2 becomes the only Internet connection for LAN users. Meantime the router still continues pinging two ISP1s IP addresses and once they become reachable back ISP1 is added to ISP2 as an active Internet connection link. Such failover scenario works in absolutely the same way for ISP2. Usually this is reasonable idea to ping IP addresses of each providers DNS servers when monitoring availability of each ISP. Miscellaneous details. Notice that CEF per packet load balancing requires IOS version of 1. IOS version so you have to make sure your Cisco router runs at least 1. E. g. c. 72. 00 ik.
