Configuring MTU Signaling in RSVPs (NSM Procedure)
318
Table 170: Named Path Configuration Details
Task
Create a named path.
Specify the sequence of
explicit routers that form
the path.
To configure maximum transmission unit (MTU) signaling in RSVP, you need to configure
MPLS to allow IP packets to be fragmented before they are encapsulated in MPLS. You
also need to configure MTU signaling in RSVP. For troubleshooting purposes, you can
configure MTU signaling alone without enabling packet fragmentation.
To configure MTU signaling in RSVP in NSM:
In the NSM navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device to select it.
2.
Click the Configuration tab. In the configuration tree, expand Protocols.
3.
Select Mpls.
4.
Add or modify settings as specified in Table 171 on page 318.
5.
Click one:
6.
OK—Saves the changes.
Cancel—Cancels the modifications.
Table 171: Path MTU Configuration Details
Task
Configure MTU options for
MPLS paths, including
packet fragmentation and
MTU signaling.
Your Action
1.
Click Path next to Mpls.
2. Click Add new entry next to Path.
3. In the Name box, enter the hostname.
4. In the Comment box, enter the comment.
1.
Click Path List next to Path.
2. In the Name box, enter the Name that identifies the sequence
of nodes that form an LSP.
3. In the Comment box, enter the comment.
4. Select one of the following:
loose—indicate that the next address in the path statement
is a loose link. This means that the LSP can traverse through
other routers before reaching this router.
strict—indicate that the LSP must go to the next address
specified in the path statement without traversing other
nodes.
Your Action
1.
Click Path Mtu next to Mpls.
2. Select the Enable Feature check box to enable the option.
3. In the Comment box, enter the comment.
4. Select the Allow Fragmentation check box to allow IP packets
to be fragmented before they are encapsulated in MPLS.
