The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] LDP-MIB extensions
Hi everybody, Attached text file listing the comments on the LDP-MIB and proposal for the extensions. Note that most of the extension/changes have been discussed during Saturday's (the day before IETF) MPLS-MIB review meeting and found very useful. Please provide your feedback before Joan includes them in the LDP-MIB draft. Thanks, Riza.

mplsLdpEgressLabelType OBJECT-TYPE
SYNTAX INTEGER {
explicitNull (1),
implicitNull (2)
}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"LDP Egress Label Type.
This object specifies the type of label to be advertised
by the LSR for FECs for which it is configured as the
Egress node.
A value of explicitNull (1) for this object specifies
that a value of 0 will be advertised as the label.
A value of implicitNull (2) for this object specifies
that a value of 3 will be advertised as the label.
Any modification of this object will result in the
withdrawal and re-advertisement of all FECs for which the
node is egress."

DESCRIPTION
"The interval after which a hello is transmitted

DESCRIPTION

DESCRIPTION
"This specifies whether loopback or interface address is to
be used in the transport address TLV in the hello messages.
If the value is set to interface(1), the IP address of
the interface via which the hello message is sent will be used
as the transport address in the hello message.
If the value is set to loopback(2), the IP address of
loopback interface shall be used as the transport
address in the hello message.
Note that any change in the status of the interface whose
address is being used as transport address will result in
re-establishment of all sessions using this as transport
address."
