Hi All
Can someone explain exactly how arp cache works.
Basically I'm trying to figure out the which gateway to add for ip address (e.g 10.2.80.9)
i have pinged the above ip obviously there is no static route in the server to get to that ip hence it fails, i have then run
arp -an|head, Not exactly sure how it works from here and what we need to look at, usually it say something "incomplete entry" etc ?
Thanks in advance
Solved! Go to Solution.

Re: arp cache query
Which gateway to add for a given IP depends on which gateways on the locally connected subnets know how to get to that IP. Once determined, that would involve route(1m) commands to manipulate the routing table, and perhaps sam or vi to edit the /etc/rc.config.d/netconf file.
None of that involves ARP. ARP is for mapping (perceived to be) local IP addresses to MAC (Ethernet) addresses.

Re: arp cache query
Thanks for the response, It's not default gateway, I'm trying to work out the static route to be added on the local unix box so it can communicate to the destination ip ie 10.x.x.x...
fw is allowing everything.
what i have done in one of the other server to work this, I have pinged the destination ip in question and then did arp -an...that showed me an incomplete route which I have used to determine what static route can be added on the local hos so it knows how to communicate with the target ip...
