Objectives
The simulator ticks each one as soon as the network meets it.
Try to install on CL1: it says GW2’s eth1 isn’t in the virtual address’s network. On GW2, set eth1 to 192.168.1.3/24, and save config.
Install on CL1.
cphaprob state on GW1 says the other member is not seen, because GW2’s sync interface is off. Turn eth4 on, on GW2, and save config.
One member is active and the other standby, and PC1 reaches 8.8.8.8.
Before you start
When members can’t see each other, each stays active, and both answer on the virtual addresses. That’s why the sync link matters. cphaprob -a if shows each virtual address and the member’s own.
Concept
A cluster shares virtual addresses
Two gateways act as one. Each keeps its own address, and the active member answers on the shared virtual ones, which is what hosts and routers use. A direct sync cable lets each see the other. Without it, each thinks it is alone and both stay active.
