M Commands
This chapter describes the Cisco NX-OS Enhanced Interior Gateway Routing Protocol (EIGRP) commands that begin with M.
maximum-paths (EIGRP)
To control the maximum number of parallel routes that the Enhanced Interior Gateway Routing Protocol (EIGRP) can support, use the maximum-paths command. To remove the maximum-paths command from the configuration file and restore the default, use the no form of this command.
maximum-paths maximum
no maximum- paths
Syntax Description
maximum |
Maximum number of parallel routes that EIGRP can install in a routing table. The range is from 1 to 16 routes. |
Command Default
8 paths
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode
Command History

|
|
|---|---|
6.0(2)N1(1) |
This command was introduced. |
Usage Guidelines
Use the maximum-paths command to allow EIGRP to install multiple paths into the routing table for each prefix. Multiple paths are installed for both internal and external routes that are learned in the same autonomous system and that have an equal cost (according to the EIGRP best path algorithm).
This command requires the LAN Base Services license.
Examples
This example shows how to allow a maximum of 10 paths to a destination:
switch(config)# router eigrp 1
switch(config-router)# maximum-paths 10
switch(config-router)#

|---|---|
copy running-config startup-config |
Saves the configuration changes to the startup configuration file. |
show ip eigrp |
Displays EIGRP information. |
metric maximum-hops
To advertise that those Enhanced Interior Gateway Routing Protocol (EIGRP) routes with a higher hop count than you specified are unreachable, use the metric maximum-hops command. To reset the value to the default, use the no form of this command.
metric maximum-hops hops-number
no metric maximum-hops
Syntax Description
hops-number |
Maximum hop count. The range is from 1 to 255 hops. |
Command Default
hops-number: 100
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode
Command History

|
|
|---|---|
6.0(2)N1(1) |
This command was introduced. |
Usage Guidelines
Use the metric maximum-hops command to provide a safety mechanism that causes EIGRP to advertise routes with a hop count greater than the value assigned to the hops-number argument as unreachable.
This command requires the LAN Base Services license.
Examples
This example shows how to configure a hop count to 200:
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# metric maximum-hops 200
switch(config-router-af)#

metric weights |
Tunes the EIGRP metric calculations. |
metric weights
To tune the Enhanced Interior Gateway Routing Protocol (EIGRP) metric calculations, use the metric weights command. To reset the values to their defaults, use the no form of this command.
metric weights tos k1 k2 k3 k4 k5
no metric weights
Syntax Description
k1—The range is from 0 to 255. The default is 1. Command Default
tos: 0
k1: 1
k2: 0
k3: 1
k4: 0
k5: 0
Command Modes
Address-family configuration mode
Router configuration mode
Router VRF configuration mode

|---|---|
6.0(2)N1(1) |
This command was introduced. |
Usage Guidelines
Use the metric weights command to alter the default behavior of EIGRP routing and metric computation and allow the tuning of the EIGRP metric calculation for a particular type of service (ToS).
This command requires the LAN Base Services license.
Examples
This example shows how to set the metric weights to change the default values:
switch(config)# router eigrp 1
switch(config-router) address-family ipv4 unicast
switch(config-router-af)# metric weights 0 2 0 2 0 0
switch(config-router-af)#
