Hi, I understand that when configuring HSRP for load-balancing we use two HSRP groups and subsequently have two different HSRP IP addresses for each of the groups. Therefore, from a PC's perspective there are two different gateway addresses to be configured.My question is: Can a DHCP server be configured to supply 2 different gateway addresses to the PC's ?If the PC's are allowed to receive two different gateway IP addresses what underlying method does the PC use to change from one gateway to the other ?Cheers,Phil.
Another alternative to what Roberto stated above is to configure 2 HSRP groups for every VLAN and make one router the active for one group and standby for the 2nd group and the opposite on the 2nd router. There's a good example at the following link.http://www.cisco.com/en/US/tech/tk648/t ... 0.shtmlPls. rate all helpful posts.HTH,Sundar
Sundar, This alternative that you mention is what my original most was about. i.e using 2 HSRP groups for every Vlan would require 2 HSRP IP addresses.Hence the PC's need to point to one of 2 different gateway addresses should one of the switches fail.My original question was how this is achieved ?Regards,Phil.
I don't know if you looked at the CCO link I had on my previous post.Anyway, that example has 2 routers configured with 2 HSRP groups. R1 is the active router for 1 group with a standby IP of 184.108.40.206 and R2 is the active router for the 2nd group with a standby IP of 220.127.116.11. Half the hosts on the LAN will use 18.104.22.168 as their default gateway and the other half will use 22.214.171.124 as their gateway. Should one of the switches become unreachable the standby router should take over and route all the traffic. This solution provides load balancing + redundancy for your LAN.HTH,Sundar
