Re: [j-nsp] Quick way to Shift MPLS traffic away from an interface

Re: [j-nsp] Quick way to Shift MPLS traffic away from an interface
Hi Tim, If you are using LDP then traffic will automatically switch to follow the IGP. No clearing of LSPs required.

Re: [j-nsp] Quick way to Shift MPLS traffic away from an interface
Hi, I assume that you are talking for RSVP signaled LSPs. clear mpls optimize aggressive-optimize - will work only on the ingress PE. There are some scripts that you can use to find out what LSPs are transiting particular interface - like this one script http://juniper.cluepon.net/index.php/Show-lsp-interface.slax. You can use clear rsvp session to force all transit LSPs to reoptimze after you increase the metric on the router you want to steer the traffic away. This could cause some traffic loss, but you don't need to go on every ingress PE to run clear mpls optimize. You can try to script it and run it on all PEs.
