PurposeCommand or Action
(Optional) Sets the router to purge LSPs received with
checksum errors.
ignore-lsp-errors disable
Example:
Step 8
RP/0/RP0/CPU0:router(config-isis)#
ignore-lsp-errors disable
Enters interface configuration mode.
interface type interface-path-id
Example:
Step 9
RP/0/RP0/CPU0:router(config-isis)# interface
GigabitEthernet 0/1/0/3
(Optional) Configures the amount of time between each
LSP sent on an interface.
lsp-interval milliseconds [ level { 1 | 2 }]
Example:
Step 10
RP/0/RP0/CPU0:router(config-isis-if)# lsp-interval
100
(Optional) Configures the interval at which periodic CSNP
packets are sent on broadcast interfaces.
csnp-interval seconds [ level { 1 | 2 }]
Example:
Step 11
• Sending more frequent CSNPs means that adjacent
routers must work harder to receive them.
RP/0/RP0/CPU0:router(config-isis-if)#
csnp-interval 30 level 1
• 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/RP0/CPU0:router(config-isis-if)#
retransmit-interval 60
Step 12
RP/0/RP0/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:
• This time is usually greater than or equal to the
lsp-interval command time because the reason for
RP/0/RP0/CPU0:router(config-isis-if)#
retransmit-throttle-interval 1000
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:
Step 14
• This command is appropriate only for an NBMA
network with highly meshed, point-to-point
topologies.
RP/0/RP0/CPU0:router(config-isis-if)# mesh-group
