Ensuring Compatibility with JUNOS 9.1 and Earlier Releases for P2MP LSPs

By default, Resv messages which include the S2L_SUB_LSP object are accepted. However, in a network which includes Juniper Networks devices running both JUNOS 9.2 and later releases and JUNOS 9.1 and earlier releases, it is necessary to configure the no-p2mp-sublsp statement on the JUNOS 9.2 and later devices to ensure that P2MP LSPs function properly. In JUNOS 9.1 and earlier releases, Resv messages which included the S2L_SUB_LSP object were rejected by default.

To ensure compatibility with JUNOS 9.1 and earlier releases, include the no-p2mp-sublsp statement:




no-p2mp-sublsp;

You can include this statement at the following hierarchy levels:

[edit protocols rsvp]
[edit logical-systems logical-system-name protocols rsvp]
