What is no passive-interface in EIGRP?
Passive EIGRP interfaces do not send out or process EIGRP hellos, which prevents EIGRP from forming adjacencies on that interface. To configure an EIGRP interface as passive, you use the command passive-interface interface-id under the EIGRP process for classic configuration.
What does no passive-interface mean?
So,”no passive-interface vlan2″ means that the OSPF peering is over vlan 2 with the neighboring router. more info: In Open Shortest Path First (OSPF), hello packets are not sent on an interface that is specified as passive.
How do I enable EIGRP on interface?
To configure EIGRP in the Cisco IOS, just follow these steps:
- Set the bandwidth on your interfaces using the bandwidth command.
- Start the EIGRP routing process and specify your AS number.
- Once you are through this stage, next step is to instruct the router in order to advertise the networks that are directly linked to it.
What is passive-interface default in EIGRP?
The Default Passive Interfaces feature simplifies the configuration of distribution devices and allows the network administrator to obtain routing information from interfaces in ISPs and large enterprise networks.
What is the command for EIGRP?
The first command, router eigrp ASN_NUMBER, enables EIGRP on a router. ASN_NUMBER represents an autonomous system number and has to be the same on all routers running EIGRP, otherwise routers won’t become neighbors.
How do I check my EIGRP status?
debug ip eigrp Examples. You can use the debug ip eigrp command to verify EIGRP operation. This command displays EIGRP packets that this router sends and receives. Example 3-34 shows the contents of the updates that are reported when you use the debug ip eigrp command on R2 to monitor when an interface on R1 comes up.
Where do you configure the passive-interface command?
To configure an interface as a passive interface in EIGRP, you’ll use the passive-interface interface#/# command in EIGRP router configuration mode. To verify rather or not an interface is in passive-mode you can use the show ip protocols command in privileged mode.
How do you remove a passive-interface?
Disable the RIP Passive Interface
- On switch 1, enter the configuration mode for the router. SEFOS# configure terminal SEFOS(config)# router rip SEFOS(config-router)# network 10.0.0.1.
- Disable the passive interface status for VLAN 1.
- Review the RIP interface for the periodic updates sent over the interface.
What command starts the EIGRP routing process?
To start an EIGRP for IPv6 routing configuration process, provide command as ipv6 router eigrp 1, where AS number is denoted as 1. The EIGRP for the IPv6 needs the 32 bit address for a router ID. Then use the command router id to configure a router ID in a router configuration mode.
Why is EIGRP not working?
Check for bad physical infrastructure. Ensure that router ports are plugged into the correct hubs. Check for filters blocking EIGRP packets. Verify router configurations — check IP addresses, masks, EIGRP AS numbers, and the network numbers defined under EIGRP.
How do I fix EIGRP stuck in active?
The tool that you need to troubleshoot the EIGRP stuck in active error is the show ip eigrp topology active command. This command shows what routes are currently active, how long the routes have been active, and which neighbors have and have not replied to the query.
How do I check my EIGRP route?
To verify that the router recognizes EIGRP routes for any neighbors, use the show ip route eigrp command, as shown in Example 3-26. Example 3-27 exhibits the show ip route command, which displays the full IP routing table, including the EIGRP routes.
Which commands are used for implementing EIGRP on Cisco router?
Use the show ip eigrp interfaces [type number] [as-number] command to determine on which interfaces EIGRP is active, and to learn information about EIGRP that relates to those interfaces. If you specify an interface by using the type number option, only that interface is displayed.
How do I troubleshoot EIGRP configuration?
Ensure that router ports are plugged into the correct hubs. Check for filters blocking EIGRP packets. Verify router configurations — check IP addresses, masks, EIGRP AS numbers, and the network numbers defined under EIGRP. Increase the hello-interval/hold-time on congested networks.
