I tried testing Sham link and its ok.. But I couldn't understand these lines from Cisco website...<<If a prefix is learned across the sham-link and the path via the sham-link is selected as the best, the PE router does not generate an MP-BGP update for the prefix. It is not possible to route traffic from one sham-link over another sham-link.>>> from the foll page..
Sham-Link is used when you have connectivity between your Customer site via Backbone as well as MPLS VPN network. So in some case customer wants MPLS VPN connectivity as a primary link but here at the both the termination PE redistribution will take place so in customer end those router will appear as a inter-area or external routes depends on configuration and back-door link will be as a intra-area routes. so normally backdoor link will be prefer as a primary path between CE link... now configuring MPLS VPN link as a sham-link you are putting that MPLS VPN link as a Intra-Area routes along with sham-link you are configuring the metric too so here you can influence the primary link election between Backdoor and the sham-link.
