isis authentication send-only [level-1 | level-2] | Used when configuring authentication without breaking existing adjacencies, this command sends authentication information, but doesn't expect to receive matching authentication information. |
isis csnp-interval seconds {level-1 | level-2} | Specifies the interval in which an IS-IS Designated Router sends CSNPs. |
isis hello-interval seconds {level-1 | level-2} | Specifies the interval between transmissions of IS-IS Hello PDUs. |
isis hello-multiplier multiplier {level-1 | level-2} | Specifies the number of IS-IS Hello PDUs a neighbor must miss before declaring its adjacency to the originating router down. |
isis lsp-interval milliseconds | Changes the default delay between transmissions of LSPs on an interface. |
isis mesh-group [number | blocked] | Assigns an interface to a numbered mesh group, or entirely blocks LSP flooding on the interface. |
isis metric default-metric {level-1 | level-2} | Specifies an interface's IS-IS default metric. |
isis password password {level-1 | level-2} | Configures authentication between two IS-IS neighbors. |
isis priority value {level-1 | level-2} | Specifies the priority of an interface to be used for DR election. |
isis retransmit-interval seconds | Specifies the time a router will wait for an acknowledgment after sending an LSP on a point-to-point link before retransmitting the LSP. |
is-type {level-1 | level-1-2 | level-2-only} | Configures the router as an L1, L1/L2, or L2 IS-IS router. |
log-adjacency-changes | Sends all adjacency change events to the log. |
lsp-refresh-interval seconds | Changes the default period between refreshes of locally originated LSPs. |
lsp-gen-interval [level-1 | level-2] lsp-max-wait [lsp-initial-wait lsp-second-wait] | Changes the default values for the exponential backoff algorithm regulating the generation of LSPs. |
max-lsp-lifetime seconds | Changes the default value of the Remaining Lifetime of locally originated LSPs. |
Metric-style [narrow | wide | transition] (level-1 | level-2 | level-1-2} | Specifies the type of metric style to use. |
Multi-topology {transition} | Enables multi-topology for IPv6. |
net network-entity-title | Configures an IS-IS router's NET. |
prc-interval prc-max-wait [prc-initial-wait prc-second-wait] | Changes the default values for the exponential backoff algorithm used with partial route calculations. |
Redistribute isis {ip} level-2 into level-2 distribute-list [access-list number | prefix-list name] | Enables leaking of routes from IS-IS level-2 into level-1 areas. |
router isis [tag] | Enables an IS-IS routing process. |
set-overload-bit [on-startup {seconds} | wait-for-bgp] [suppress {[interlevel] | [external]}] | Manually sets the Overload bit in a router's LSP to one. |
show clns is-neighbor [type number] [detail] | Displays the IS-IS neighbor table. |
show clns protocol | Displays information about how clns and integrated IS-IS is configured on the router. |
show isis database [level-1] [level-2] [l1] [l2] [detail] [lspid] | Displays an IS-IS link-state database. |
