cluster arp 一問

[watermelonyu]

現在有兩台 node1, node2 為 TruCluster, 它們的 cluster host name 是 node, 當我從 client 去 ping node 的時候, client 的 arp cache 會得到哪一台的 MAC address?

Hello FJ:



You must login your cluster to check which

node is Proxy ARP master:

For axample:

# arp -an | grep perm

172.16.188.71 at 00-60-cf-21-87-d6 permanent published

172.16.12.71 at 00-0b-dc-b4-0a-a8 permanent published



Then your client should get arp cache with

00-60-fc-12-87-d6 for subnet 172.16.188.xx and

00-0b-dc-b4-0a-a8 for subnet 172.16.12.xx.



This example is a TruCluster with two

network interfaces, each subnet has one cluster

alias ip.



If you have any other questoin, please let

us know.
