Not exactly what you asked about, but you can force a routing instance to
use a different LSP like this:
policy-statement lsp-mapper {
term 1 {
from {
rib bgp.l3vpn.0;
community use-lsp;
}
then {
install-nexthop strict lsp lsp;
accept;
}
}
term 2 {
from rib bgp.l3vpn.0;
then {
install-nexthop strict except lsp lsp;
accept;
}
}
}
set routing-options forwarding-table export lsp-mapper
The LSP named "lsp" will be used for routes with the "use-lsp" community,
which can be set by the VRF's export policy on the originating router. All
other routes will use anything except "lsp".
I doubt it's possible to have a VRF use a given LSP's secondary path.
