Usage guidelines
When advertising label bindings to peers, an LSR follows these rules:
If the IP prefix of a label binding to be advertised fails the IP prefix checking, the LSR does not
•
advertise the label binding to any peer.
If the IP prefix of a label binding to be advertised passes the IP prefix checking and the peer list is
•
not specified, the LSR will advertise the label binding to all peers.
If the IP prefix of a label binding to be advertised passes the IP prefix checking and a peer list is
•
specified, the LSR will advertise the label binding to the peers that pass the peer list checking.
If the IP prefix of a label binding to be advertised passes the checking of more than one IP prefix lists
•
(which are specified by executing the advertise-label command for multiple times), the LSR will
advertise the label binding based on the configuration by the first advertise-label command.
