Implementing IS-IS
Step 6
lsp-mtu bytes [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis)# lsp-mtu 1300
(Optional) Sets the maximum transmission unit (MTU) size of LSPs.
Step 7
max-lsp-lifetime seconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis)# max-lsp-lifetime 11000
(Optional) Sets the initial lifetime given to an LSP originated by the router.
• This is the amount of time that the LSP persists in the database of a neighbor unless the LSP is regenerated or
refreshed.
Step 8
ignore-lsp-errors disable
Example:
RP/0/RP0/CPU0:router(config-isis)# ignore-lsp-errors disable
(Optional) Sets the router to purge LSPs received with checksum errors.
Step 9
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-isis)# interface HundredGigE 0/1/0/3
Enters interface configuration mode.
Step 10
lsp-interval milliseconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# lsp-interval 100
(Optional) Configures the amount of time between each LSP sent on an interface.
Step 11
csnp-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# csnp-interval 30 level 1
(Optional) Configures the interval at which periodic CSNP packets are sent on broadcast interfaces.
• 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.
Step 12 retransmit-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-if)# retransmit-interval 60
