Parameters

min-bandwidth: Specifies the minimum bandwidth in the range of 1 to 4294967295 Kbps.

total-delay: Specifies the total delay in the range of 1 to 16777215 in 10 microseconds.

reliability: Specifies the minimum reliability value in the range of 1 to 255. A greater value means higher reliability. 1 means completely unreliable. 255 means completely reliable.

load: Specifies the maximum load in the range of 1 to 255. A smaller value means an idler link.

mtu: Specifies the minimum MTU in the range of 1 to 65535 bytes.

Usage guidelines

EIGRP calculates the composite metric for a route by using the configured metrics and the weights assigned to them. For information about how to calculate the composite route metric, see the metric weights command.

If you do not set the metrics in the import-route command, EIGRP uses the settings in the default-metric command for composite metric calculation.

Examples

# For EIGRP process 1, set the bandwidth, delay, reliability, load, and MTU metric values for redistributed routes to 111, 2220, 33, 44, and 555, respectively.

seconds: Specifies the hello timer in the range of 1 to 65535 seconds.

Usage guidelines

A smaller hello timer means a faster speed for detecting topology changes, which consumes more system resources. Set an appropriate hello timer based on your network condition.

As a best practice, set the hold timer to be at least three times the hello timer.

Examples

# Set the hello timer to 20 seconds for EIGRP process 1 on Ten-GigabitEthernet 3/1/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 3/1/1

Parameters

eigrp-as: Specifies an EIGRP process by its AS number in the range of 1 to 65535.

seconds: Specifies the hold timer in the range of 1 to 65535 seconds.

Usage guidelines

The router advertises the hold timer to the neighbor. If the neighbor receives no Hello packets from the local router within the hold time, it determines that the local router is invalid.

As a best practice, set the hold timer to be at least three times the hello timer.

Examples

# Set the hold timer to 60 seconds for EIGRP process 1 on Ten-GigabitEthernet 3/1/1.

Parameters

bgp: Redistributes BGP routes.

direct: Redistributes direct routes.

static: Redistributes static routes.

unr: Redistributes user network routes. User network routes are generated by access devices for online users.

eigrp: Redistributes EIGRP routes.

isis: Redistributes IS-IS routes.

rip: Redistributes RIP routes.

ospf: Redistributes OSPF routes.

as-number: Redistributes routes in an AS specified by its number in the range of 1 to 4294967295. If you do not specify this argument, the command redistributes all IPv4 EBGP routes. As a best practice, specify an AS number to prevent the system from redistributing excessive IPv4 EBGP routes.

eigrp-as: Specifies an EIGRP process by its AS number in the range of 1 to 65535. The default value is 1.

all-as: Specifies all EIGRP processes.

process-id: Specifies a process by its ID for IS-IS, OSPF, or RIP, in the range of 1 to 65535. The default value is 1.

all-processes: Redistributes routes from all the processes of IS-IS, OSPF, or RIP.

allow-ibgp: Redistributes IBGP routes.

allow-direct: Redistributes the networks of the local interfaces enabled with the EIGRP process. If you do not specify this keyword, the networks of the local interfaces are not redistributed.

metric: Configures metrics for redistributed routes.

min-bandwidth: Specifies the minimum bandwidth in the range of 1 to 4294967295 Kbps.

total-delay: Specifies the total delay in the range of 1 to 16777215 in 10 microseconds.

reliability: Specifies the minimum reliability value in the range of 1 to 255. A greater value means higher reliability. 1 means completely unreliable. 255 means completely reliable.

load: Specifies the maximum load in the range of 1 to 255. A smaller value means an idler link.

mtu: Specifies the minimum MTU in the range of 1 to 1500 bytes.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

The import-route bgp command redistributes only EBGP routes. Because the import-route bgp allow-ibgp command redistributes both EBGP and IBGP routes and might cause routing loops, use it with caution.

Only active routes can be redistributed. To view route state information, use the display ip routing-table protocol command.

The undo import-route { isis | ospf | rip } all-processes command removes only the configuration made by the import-route { isis | ospf | rip } all-processes command. It does not remove the configuration made by the import-route { isis | ospf | rip } process-id command.

The undo import-route eigrp all-as command removes only the configuration made by the import-route eigrp all-as command. It does not remove the configuration made by the import-route eigrp eigrp-as command.

You can set the metric values used for composite route metric calculation in the import-route command. If you do not set the metric values, the settings in the default-metric command apply.

Parameters

K1: Specifies the weight for K1, in the range of 0 to 255.

K2: Specifies the weight for K2, in the range of 0 to 255.

K3: Specifies the weight for K3, in the range of 1 to 255.

K4: Specifies the weight for K4, in the range of 0 to 255.

K5: Specifies the weight for K5, in the range of 0 to 255.

Usage guidelines

EIGRP calculates the composite route metric based on the following metrics:

·     Bandwidth—Minimum interface bandwidth on the path from the local router to the destination network.

·     Delay—Sum of all interface delays on the path from the local router to the destination network.

·     Reliability—Minimum interface reliability value on the path from the local router to the destination network.

·     Load—Maximum interface load value on the path from the local router to the destination network.

·     MTU—Minimum interface MTU on the path from the local router to the destination network.

EIGRP assigns each metric a weight for calculating the composite route metric. The calculation formula uses coefficients (K values) that correspond to the metrics as follows:

·     K1—Bandwidth.

·     K2—Load.

·     K3—Delay.

·     K4—Reliability.

·     K5—MTU.

EIGRP calculates the composite route metric as follows:

·     If K5 is equal to 0, the following formula applies:

Metric 1 = 256 × [K1 × Bandwidth + (K2 × Bandwidth) / (256 - Load) + K3 × Delay]

·     If K5 is not equal to 0, Metric 1 is multiplied by another coefficient as follows:

Metric 2 = Metric 1 × [K5 / (Reliability + K4)]

In the formula: Bandwidth = 10000000 / Minimum interface bandwidth on the path.

Examples

# For EIGRP process 1, configure the weights for metrics K1 through K5 as 11, 22, 33, 44, and 55, respectively.

Parameters

network-address: Specifies a network by its IP address. You can specify the IP addresses of networks where the local interfaces reside.

wildcard-mask: Specifies the wildcard mask of the IP address. For example, the wildcard mask of mask 255.0.0.0 is 0.255.255.255. If you do not specify this argument, the natural mask applies.

Usage guidelines

This command allows you to enable EIGRP for a network. After that, only the interface attached to the network runs EIGRP.

Examples

# Enable EIGRP process 1 for the network 129.100.0.0.

Parameters

internal-preference: Specifies the internal route preference in the range of 1 to 255. The smaller the value, the higher the preference.

external-preference: Specifies the external route preference in the range of 1 to 255. The smaller the value, the higher the preference.

Usage guidelines

Routing protocols each have a default preference. If they find multiple routes destined for the same network, the route found by the routing protocol with the highest preference is selected as the optimal route.

This command allows you to configure the preference for internal routes learned from the same EIGRP process, and for external routes learned from other EIGRP processes or routing protocols.

Examples

# Configure the internal route preference and external route preference for EIGRP process 1 as 100 and 190, respectively.

Parameters

router-id: Specifies the router ID in IPv4 address format. The router ID cannot be 0.0.0.0 or 255.255.255.255.

Usage guidelines

	CAUTION: Changing the router ID for an EIGRP process will reset the neighbor relationship.

 

EIGRP uses a router ID to uniquely identify an advertising router in an autonomous system. If a router receives a route containing the router ID of the local router, it discards the route.

As a best practice, to enhance network availability, specify the IP address of a loopback interface as the router ID.

Examples

# Configure the router ID for EIGRP process 1 as 10.1.1.3.

<Sysname> system-view

[Sysname] eigrp 1

network-admin

Parameters

time-limit: Specifies the convergence wait timer in the range of 1 to 65535 minutes.

disable: Sets no time limit for route convergence.

Usage guidelines

If a route in the topology table enters the Active state and fails to be converged within the convergence wait time, it gets stuck in the active (SIA) state. The router no longer waits for replies from neighbors, and terminates the relationship with the neighbors that have not responded.

The disable keyword means setting no time limit for route convergence. Typically, as a best practice, do not specify this keyword.

Parameters

seconds: Specifies the aging timer in the range of 20 to 300 seconds.

Usage guidelines

During the graceful restart (GR) process, the GR restarter and GR helper exchange routing information. If route exchange is not completed when the specified aging timer expires, the GR helper (EIGRP router) quits the GR process. The GR helper updates the RIB entries based on the learned EIGRP routes and removes aged RIB entries.

Examples

# Set the aging timer to 100 seconds for routes on the GR helper in EIGRP process 1.
