Expert
Can you explain what the "g"(in g=192.168.20.1) means in below debug ip packet and icmp?
and what "tableid=0" mean ? The below debug message is from the link. Thank you so much.

Hello,

I believe the g stands for gateway which is the IP address used to route to another network or the Internet.  Typically this is the IP address of a router.

I'm not fully sure for tableid, but it should refer to the routing table, since it is zero, there is probably only one table in your setup.

Here is a little more info about the routing table setup:

Also, to my understanding it can mean which VLAN the log is referring to.  So if you have multiple VLANs on your network which are managed by your cisco device, then the first VLAN would be tableid 0 and the next VLAN can be tableid 1 and so on.

If you only have just one network, then tableid should always be zero.
