VLANs are created in the VLAN database, and ports are assigned to relevant VLANs.

VLANs

 

 

The access lists are assigned in order to the individual switch ports as access groups. The

 

order in which the access groups are attached to a port is important - packets are matched

 

against the ACLs in the order they are attached to the interface.

 

In this example, three access groups are attached to port 1.0.1.

 

The first access group allow_to_self_10 permits traffic that has destination IP (192.168.10.0/

 

24) within the same IP subnet that the switch port is a member of.

 

The second access group access43 permits traffic that has destination IP (192.168.43.0/24)

 

within the external shared router subnet. This allows VRF red to access the subnet

 

192.168.43.0/24 via the shared VRF.
