VLAN is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. Inter VLAN is defined as two VLANS connected to each other and communicating.
hiya my name is shaggy hat you wuu2
A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.
Access like carry the single vlan information & Trunk link able to carry the multiple vlan information when frames are travels from trunk mani shanker
Switch(config)# ip default-gateway 192.168.1.254Switch(config)# interface vlan 1Switch(config-if)# ip address 192.168.1.1 255.255.255.0Switch(config-if)# interface fa0/1Switch(config-if)# switchport access vlan 1
Since VLAN's cannot communicate with other VLAN's directly, I believe you would have to set up a router to do that. I would check out how to set up a bridge between two VLAN's.
force the port to be a part of a single vlan
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.

• Access link: An access link is a link that is part of only one VLAN, and normally access links are for end devices. Any device attached to an access link is unaware of a VLAN membership. An access-link connection can understand only standard Ethernet frames. Switches remove any VLAN information from the frame before it is sent to an access-link device.• Trunk link: A Trunk link can carry multiple VLAN traffic and normally a trunk link is used to connect switches to other switches or to routers. To identify the VLAN that a frame belongs to, Cisco switches support different identification techniques (VLAN Frame tagging). Our focus for CCNA examination is on Inter-Switch Link (ISL) and 802.1Q.A trunk link is not assigned to a specific VLAN. Many VLAN traffic can be transported between switches using a single physical trunk link.
A VLAN trunk allows for data to travel across a single link between two devices even if the data is from multiple VLANs. This allows for reduced cabling needed as for you won't have to run multiple cables between switches in order to have up-links for every VLAN.
