How to Handle Overlaps when Sending VLANs and Subnets to Different Tools
1 shows how to use map priority when handling packets matching criteria in multiple maps. In this example, we want to achieve the following results:
| Send packets on the 172.16.0.0 subnet to 1/2/x1 |
| Send packets on the 172.17.0.0 subnet to 1/2/x2 |
| Send packets on VLAN 100 to 1/2/x3 |
The trick is in how to handle packets on either 172.16.0.0 or 172.17.0.0 and VLAN 100. In this example, we use map priority to ensure that packets such as this are sent to both of their desired destinations.
Notice that the first two maps configured in 1.
The same principle is applied in map2 for packets on 172.17.0.0 and VLAN 100.
Note: If we did not observe the order of map entry shown in 1.
