Dynamic
LSPs
Dynamic LSPs use signaling protocols to establish themselves
and propagate LSP information to other LSRs in the network. You configure
the inbound router with LSP information that is transmitted throughout
the network when you enable the signaling protocols across the LSRs.
Because the LSRs must exchange and process signaling packets and instructions,
dynamic LSPs consume more resources than static LSPs. However, dynamic
LSPs can avoid the network black holes of static LSPs by detecting
topology changes and outages and propagating them throughout the network.
