we are wokring on a project for a company with an office in Kuala Lumpur. The office currently has a VDSL circuit with Telekom Malaysia which has also provided them with a VDSL modem. I've been told that Telekom Malaysia is tagging the traffic and is using VLAN500 to do so. We have decided to use Cisco 2921 for our network, connect it to the VDSL modem and setup VLAN tagging for VLAN500 on the WAN interface of the Cisco but some of our consultants disagree that this will work.
My question is; has anyone ever dealt with configuring a Cisco device for a Malaysian ISP and if so, can what I am suggesting be done?
Our contact in Malaysia has specified that the router should have an Ethernet WAN interface, VLAN tagging capabilities on the WAN interface and be configured with a PPPoE MTU1492.
