Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
(Optional) Configures the interval at which periodic CSNP
packets are sent on broadcast interfaces.
csnp-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
csnp-interval 30 level 1
Step 11
•
Sending more frequent CSNPs means that adjacent routers
must work harder to receive them.
•
Sending less frequent CSNP means that differences in the
adjacent routers may persist longer.
(Optional) Configures the amount of time that the sending router
waits for an acknowledgment before it considers that the LSP
was not received and subsequently resends.
retransmit-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
retransmit-interval 60
Step 12
RP/0/RSP0/CPU0:router(config-isis-if)#
retransmit-interval 60
(Optional) Configures the amount of time between
retransmissions on each LSP on a point-to-point interface.
retransmit-throttle-interval milliseconds [ level
{ 1 | 2 }]
Step 13
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
retransmit-throttle-interval 1000
•
This time is usually greater than or equal to the lsp-interval
command time because the reason for lost LSPs may be
that a neighboring router is busy. A longer interval gives
the neighbor more time to receive transmissions.
(Optional) Optimizes LSP flooding in NBMA networks with
highly meshed, point-to-point topologies.
mesh-group { number | blocked }
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
mesh-group blocked
Step 14
•
This command is appropriate only for an NBMA network
with highly meshed, point-to-point topologies.

Step 15
(Optional) Displays information about the IS-IS interface.
show isis interface [ type interface-path-id | level
{ 1 | 2 }] [ brief ]
Step 16
Example:
RP/0/RSP0/CPU0:router# show isis interface
GigabitEthernet 0/1/0/1 brief
(Optional) Displays the IS-IS LSP database.
show isis [ instance instance-id ] database [ level
{ 1 | 2 }] [ detail | summary | verbose ] [ * |
lsp-id ]
Step 17
Example:
RP/0/RSP0/CPU0:router# show isis database
level 1
(Optional) Displays LSP log information.
show isis [ instance instance-id ] lsp-log [ level
{ 1 | 2 }]
