Usage Scenario
After CSPF is enabled globally, CSPF computation is triggered once TE LSPs are to be established. In an inter-domain scenario, if a loose explicit path is configured in a P2MP template and NG MVPN triggers the creation of dynamic P2MP tunnels, CSPF that is enabled by default causes a failure to establish the P2MP tunnel. To prevent this problem, run the cspf disable command in the P2MP template to disable CSPF path computation. Then BGP or static routes are used to establish inter-domain TE tunnels.
