Example: Configuring CoS-Based Forwarding for Different Traffic Types

One common use for CoS-based forwarding and next-hop maps is to enforce different handling for different traffic types, such as voice and video. For example, an LSP-based next hop can be used for voice and video, and a non-LSP next-hop can be used for best effort traffic.

Only the forwarding policy is shown in this example:



[edit class-of-service]
forwarding-policy {


next-hop-map ldp-map {


forwarding-class expedited-forwarding {
lsp-next-hop voice;
non-lsp-next-hop;
}




forwarding-class assured-forwarding {
lsp-next-hop video;
non-lsp-next-hop;
}




forwarding-class best-effort {
non-lsp-next-hop;
discard;
}


}


}
