Example: Configuring CoS-Based Forwarding for IPv6
This example configures CoS-based forwarding (CBF) next-hop maps and CBF LSP next-hop maps for IPv6 addresses.
You can configure a next-hop map with both IPv4 and IPv6 addresses, or you can configure separate next-hop maps for IPv4 and IPv6 addresses and include the from family (inet | inet6) statements at the [edit policy-options policy-options policy-statement policy-name term term-name] hierarchy level to ensure that only next-hop maps of a specified protocol are applied to a specified route.
If you do not configure separate next-hop maps and include the from family (inet | inet6) statements in the configuration, when a route uses two next hops (whether IPv4, IPv6, interface, or LSP next hop) in at least two of the specified forwarding classes, CBF is used for the route; otherwise, the CBF policy is ignored.
- Define the CBF next-hop map:[edit class-of-service]forwarding-policy {next-hop-map cbf-map {forwarding-class best-effort {next-hop [ ::192.168.139.38 192.168.139.38 ];}forwarding-class expedited-forwarding {next-hop [ ::192.168.140.5 192.168.140.5 ];}forwarding-class assured-forwarding {next-hop [ ::192.168.145.5 192.168.145.5 ];}forwarding-class network-control {next-hop [ ::192.168.141.2 192.168.141.2 ];}}}
- Define the CBF forwarding policy:[edit policy-options]policy-statement ls {then cos-next-hop-map cbf-map;}
- Export the CBF forwarding policy:[edit routing-options]forwarding-table {export ls;}
