Additional RSVP-TE Configuration Tasks

To create a filter that determines whether and where incoming (locally assigned) labels
are distributed:
Issue the mpls ldp advertise-labels command one or more times:
host1(config)#mpls ldp advertise-labels for net25 to euro3
When you do not specify a toAccessList, the action is taken for all peers.
Consider the following example configuration.
host1(config)#mpls ldp advertise-labels for net25 to euro3
host1(config)#mpls ldp advertise-labels for boston1
In this example, suppose the LSR receives a label for destination 10.10.11.12. If net25
specifies 10.10.11.12, then the access list action—permit or deny—is taken with the
destination. If the action is permit, the peer that the label is advertised to is subject to
the access list euro3. If net25 does not include 10.10.11.12, the LSR attempts to match it
against boston1. If 10.10.11.12 is present in that access list, the specified action is taken for
all peers. If boston1 does not include the destination, the label is not advertised to any
peer.

All of the following RSVP-TE configuration tasks are optional, depending on your network
topology and needs.
Tasks to configure RSVP-TE settings based on your network topology include:
Configure RSVP MD5 authentication to provide hop-by-hop security.
See "Configuring RSVP MD5 Authentication" on page 294.
Configure fast reroute extensions to RSVP-TE to create a bypass tunnel.
See "Configuring RSVP-TE Fast Rerouting with RSVP-TE Bypass Tunnels" on page 295.
Configure RSVP-TE peers to exchange hello messages and establish a hello adjacency.
See "Configuring RSVP-TE Hello Messages to Determine Peer Reachability" on page 297.
Configure RSVP-TE graceful restart to enable routers to maintain MPLS forwarding
state when a link or node failure occurs.
See "Configuring RSVP-TE Graceful Restart" on page 298.
Configure the exchange of RSVP-TE node hellos on all RSVP-TE interfaces.
See "Configuring RSVP-TE Hellos Based on Node IDs" on page 299.
Configure the BFD Protocol for RSVP-TE.
