Chapter39 Remote Loop-Free Alternate - Fast Reroute
How to Configure Remote Loop-Free Alternate - Fast Reroute
Step 13
lsp-gen-interval [level-1 | level-2]
lsp-max-wait
[
lsp-initial-wait
lsp-second-wait
]
Example:
Router(config-router)#
lsp-gen-interval 5 50 200
Customizes IS-IS throttling of LSP generation.
• level-1—(Optional) Apply intervals to Level-1 areas only.
• level-2—(Optional) Apply intervals to Level-2 areas only.
• lsp-max-wait—Indicates the maximum interval (in seconds)
between two consecutive occurrences of an LSP being
generated. The range is 1 to 120 seconds. The default is 5
seconds.
• lsp-initial-wait—(Optional) Indicates the initial LSP
generation delay (in milliseconds). The range is 1 to 120,000
milliseconds. The default is 50 milliseconds.
• lsp-second-wait—(Optional) Indicates the hold time between
the first and second LSP generation (in milliseconds). The
range is 1 to 120,000 milliseconds. The default is 5000
milliseconds (5 seconds).
Step 14
no hello padding
Example:
Router(config-router)# no hello
padding
Reenables IS-IS hello padding at the router level.
Step 15
log-adjacency-changes
Example:
Router(config-router)#
log-adjacency-changes
Configures the router to send a syslog message when an OSPF
neighbor goes up or down.
Step 16
fast-reroute per-prefix {level-1 |
level-2} {all | route-map
route-map-name
}
Example:
Router(config-router)# fast-reroute
per-prefix level-1 all
Configures an FRR path that redirects traffic to a remote LFA tunnel
for either level 1 or level 2 packets.
• level-1—Enables per-prefix FRR of level 1 packets.
• level-2—Enables per-prefix FRR of level 2 packets.
• all—Enables FRR of all primary paths.
• route-map—Specifies the route map for selecting primary
paths for protection.
• route-map-name—Route map name.
Step 17
fast-reroute remote-lfa {level-1 |
level-2} mpls-ldp [maximum-metric
metric-value
]
Example:
Router(config-router)# fast-reroute
remote-lfa level-1 mpls-ldp
Configures an FRR path that redirects traffic to a remote LFA
tunnel.
• level-1—Enables LFA-FRR of level 1 packets.
• level-2—Enables LFA-FRR of level 2 packets.
• mpls-ldp—Specifies that the tunnel type is MPLS or LDP.
• maximum-metric—(Optional) Specifies the maximum metric
value required to reach the release node.
• metric-value—Metric value.
