Operation as VRRP daemon on Solaris


Figure 1: Network Setup of two X2100 nodes, bge0 and nge0 both connected to the same switch

nge0 interface configuration

The file /etc/hostname.nge0 contains the following line on both nodes:

172.17.2.64/24 -arp ether 00:00:5e:00:01:0e

The effect is that both nodes use the VRRP ethernet address of virtual router 14 (last octet) while not responding to arp requests.

The configuration files

Both configuration files are almost the same, they just differ in VRRP priority and in the "network real" address.

NodeA configuration file

//        configuration taken Sun Jan  7 17:37:02 2007
//        BalanceNG 1.736 (created 2007/01/07)
