Description
The ONS 15600 system identifier is set to its IEEE 802.3 MAC
address. Each ONS 15600 supports twelve OSI virtual routers. Each
router NSAP system identifier is the ONS 15600 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 15600 include:
00—Network Entity Title (NET). Used to exchange PDUs in the
•
ES-IS and IS-IS routing exchange protocols. (See the
"9.6.4.1 End System-to-Intermediate System Protocol" section
on page 9-31 and the
System-to-Intermediate System" section on page
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.
