Answer
The following configuration is an example in which class-based forwarding is applied to a VPLS. It works as expected when both RSVP LSPs are up. If one of the LSPs goes down, all traffic uses the remaining LSP.
For example, if the to-brg2-private LSP or tunnel goes down, all of the PRIVATE class traffic then uses the REALTIME tunnel.
next-hop-map NHOP-LSP-MAP {
forwarding-class REALTIME {
lsp-next-hop to-brg2-realtime;
}
forwarding-class PRIVATE {
lsp-next-hop to-brg2-private;
}
}
To change this behavior, apply a filter that only allows traffic of the specific forwarding class on each LSP:
set protocols mpls label-switched-path name policing filter name
