Command Maximum-Paths Use Controls how many equal cost paths EIGRP will loadbalance with. EIGRP can now support up to 16 paths if desired. Syntax Router(config-router)#maximum-path <1-16> Example In this example we will change the number of EIGRP maximum paths to 6. CopyR1(config)#router eigrp 100 R1(config-router)# maximum-paths 6
Command Variance (EIGRP) Use Allows EIGRP to install unequal load balancing to the routing table. Syntax Router(config-router)#variance Example In this example, we will configure R4 to utilize both links to reach R5’s loopback networks. Currently we have a basic EIGRP setup for this example CopyR4 router eigrp 222 …
Command EIGRP Router-ID Use This command manually sets the router-id for EIGRP. This is used just for administrative purposes and doesn’t affect EIGRP’s operation, since EIGRP keeps track of neighbors by their IP addresses. Syntax Router(config-router)#eigrp router-id <ID> Example In this example, we will change EIGRP’s router-id on …
Command Network Use Specifies which interfaces will participate in the EIGRP process. Syntax Router(config-router)#network <ip address> OR Router(config-router)#network <ip address> <wildcard> Example In this example, we will configure EIGRP 100 on all routers in the topology. CopyR1(config)#router eigrp 100 R1(config-router)#no auto R1(config-router)#network 10.4.4.4 R1(config-router)#network 1.1.1.1 R1(config-router)#do sh run | …
Command Distance EIGRP Use This command changes the administrative distance for EIGRP routes. Syntax Router(config-router)#distance eigrp <internal distance> <external distance> Example In this example, we will change the EIGRP administrative distance to 110. Currently, we see EIGRP is at its default administrative distance of 90. CopyR1(config)#do show ip route eigrp …
Command Passive-Interface Default Use This command prevents EIGRP from forming adjacencies on all interfaces on the router. Using no passive-interface default will allow EIGRP communication. Syntax Router(config-router)#passive-interface default Example In this example, we will use passive-interface default to block all EIGRP adjacencies. Afterwards, we will allow communication through R2’s fa0/0. CopyR2(config)#do show …
Command Distribute-List Use Allows you to filter routes from the routing table. For CCNA purposes, this is usually done through access lists. Syntax Router(config-router)#distribute-list <list> <in/out> OR Router(config-router)#distribute-list <list> <in/out> <interface> Options <list> Access list <in/out> Whether the router is receiving or sending the route Example In this …
Command No Auto-Summary Use Disables EIGRP’s default behavior to advertise networks at their classful boundary. Syntax Router(config-router)#no auto-summary Example In this example, we will disable auto-summary in the EIGRP process and observe the difference. First we will enable EIGRP on all routers for all links. CopyR1(config)#router eigrp 100 …
Command Neighbor Use This command tells RIP to communicate with unicast updates to a specific neighbor. This is usually used with the passive-interface default command to prevent all other RIP communication. Syntax Router(config-router)#neighbor <ip address> Example In this example, we will configure R4 to send its updates to R3 using …
Command Offset-List Use This command allows you to modify the metric of a route on the routing table. Syntax Router(config-router)#offset-list <list> <in or out> <offset> <interface> Options <list> = 0 All networks <list> = 1-99, 1300 – 1999 Standard accses list <list> = Name Named access list <in> …
