Description
The ONS 15454 system identifier is set to its IEEE 802.3 MAC
address. Each ONS 15454 supports three OSI virtual routers. Each
router NSAP system identifier is the ONS 15454 IEEE 802.3 MAC
address + n, where n = 0 to 2. For the primary virtual router, n = 0.
The selector field directs the protocol data units (PDUs) to the correct
destination using the CLNP network layer service. Selector values
supported by the ONS 15454 include:
00—Network Entity Title (NET). Used to exchange PDUs in the
•
ES-IS and IS-IS routing exchange protocols. (See the
"13.7.4.1 End System-to-Intermediate System Protocol" section
on page 13-38 and the
System-to-Intermediate System Protocol" section on
page 13-38.)
• 1D—Selector for Transport Class 4 (and for FTAM and TL1
applications (Telcordia GR-253-CORE standard)
AF—Selector for the TARP protocol (Telcordia GR-253-CORE
•
standard)
2F—Selector for the GRE IP-over-CLNS tunnel (ITU/RFC
•
standard)
CC—Selector for the Cisco IP-over-CLNS tunnels (Cisco
•
specific)
E0—Selector for the OSI ping application (Cisco specific)
•
NSELs are only advertised when the node is configured as an ES.
They are not advertised when a node is configured as an IS. Tunnel
NSELs are not advertised until a tunnel is created.
