Sets the Level 1 or Level 2 LSP MTU size.
Syntax: lsp-mtu size
no lsp-mtu
size
Maximum number of bytes allowed in LSPs. Valid values are 128 bytes - 4352 bytes.
Description: The LSP MTU size describes the amount of information that can be recorded in a single link state packet.
Use the lsp-mtu size command to configure the maximum number of bytes allowed in an LSP. If this command is not configured, ISIS uses the default size of 1500 bytes while transmitting LSPs for both POS and Gigabit Ethernet.
Use the no lsp-mtu command to configure the maximum number of bytes allowed in an LSP at the default value of 1497 bytes.
Factory Default: 1497 bytes.
Command Mode: Router configuration.
Example: In the following example:
- The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration,
- The lsp-mtu command sets the MTU size to 1400 bytes,
- The show running-config isis command displays the setting:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#router isis npi
router(config-router)#lsp-mtu 1400
router(config-router)#end
router#show run isis
