Chapter 6
Inter-VLAN Routing
Success rate is 80 percent (4/5), round-trip min/avg/
max = 4/5/8 ms
2621A#
The reason for the 80% success rate is that the IP hosts have not com-
municated before and the first ping timed out waiting for the ARP pro-
tocol to resolve the hardware addresses of each device.
6.
Verify that all hosts can communicate by pinging from host to host.
Lab 6.2: Internal Inter-VLAN Routing
In this second lab, you'll configure the RSM in the 5000 switch for inter-
VLAN routing using ISL. The 1900s will be configured first, then the 5000s.
The 2621 router will not be needed in this lab.
1.
Unplug the 2621 router from the 5000 series switch. The hosts should
no longer be able to ping each other.
2.
Configure the RSM on the 5000 series switch to provide inter-VLAN
routing. Use the show module command to view the RSM card
location.
