For example I have a border router with two ports, first port is wan port and another port is lan port.
How many VLANs possible to assign to a router port?

Hi Bot,
I am not sure for what purpose this designed was represented.
They could have just directly terminted the ISP to router then followed by switch will solve the purpose.

Hi Bot,
Sorry if I have misunderstood your question. As far my knowledge you cannot assign the vlans on the router.
We use the concept of intervlan routing or router on a stick.
More details on https://supportforums.cisco.com/thread/2048618
Vlan on Router:
A vlan configuration on a router is slightly different than on a switch. On a switch, you would create the vlan and then the routed vlan interface.
On a router you tie a vlan to a subinterface. You need to create the subinterface and then do the encapsulation dot1q
interface FastEthernet0/0
no ip address
speed 100
full-duplex
!
interface FastEthernet0/0.100
description test Network
encapsulation dot1Q 100
ip address 192.168.102.1 255.255.255.128
no snmp trap link-status
!
interface FastEthernet0/0.201
description Office
encapsulation dot1Q 201
ip address 205.127.102.129 255.255.255.128
no snmp trap link-status
Please feel free to provide some more details on what exactly you are looking if the above link doenst solve your purpose.

Hi Inayath,
I saw a design of network like below
ISP <--> [fastethernet0/1]SWITCH1[fastethernet0/2]<--> ROUTER<--> SWITCH2
When I asked about the SWITCH1 purpose on the scheme I was told the purpose of the SWITCH1 to terminate VLANs.
So why I asked that question.

Hello Bot,
It's totally depends upon sub interfaces which you can create for a particular port. because you can assign one interface to one VLan at one time.
