آقای منصوری از پاسخ هاتون یک دنیا ممنونم .
HSRP بدرد کار من نمیخورره چون :
Regardless of how many redundant routers you have running HSRP, you never use more than one gateway at a time. This is very inefficient in large networks, and is a waste of hardware during normal system operation. There is one very simple mechanism to avoid this: create multiple groups. This practice is logically similar to the way STP can be used to load balance switch uplinks. We create multiple groups, and make a different router active for each group using priorities. You then distribute the different virtual gateway IPs evenly among clients, so half of the clients use one group and the other half use the other group. Of course this is not the most ideal method of load balancing, since one group may produce heavy amounts of traffic and another group may not, but it's better than single group HSRP
این مشکل رو پروتوکل GLBP نداره
As was previously discussed, HSRP is effective for providing network redundancy, but it is not a very efficient technology. With a single group, redundant links sit idle. With multiple groups, very basic load balancing is possible, but it requires additional planning and administration, and does not guarantee any sort of even balancing of traffic. Gateway Load Balancing Protocol (GLBP) is an alternative to HSRP, which can provide additional load balancing features on top of redundancy.
ولی من اینجا Catalyst 3550 , 2950 دارم کهGLBP ساپورت نمیکنه
Cisco 1700 series, Cisco 2600 series, Cisco 3620, Cisco 3631, Cisco 3640, Cisco 3660, Cisco 3725, Cisco 3745, Cisco 7100 series, Cisco 7200 series, Cisco 7400 series, Cisco 7500 series
میخوام بدونم آیا معادلی برای GLBP در 3550 هست ؟
آیا روش رایجی ( حالا نه لزوما پروتوکل هایی که ذکر کردم ) برای LoadBalancing بین دو Gateway اینترنت ( با رنج آی پی مختلف و پهنای باند مختلف ) وجود داره ؟
