How is EIGRP for IPv6 configuration done?
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.
What commands are used to enable EIGRP for IPv6 on an interface?
EIGRP for IPv6 Configuration
| 1 | Enter global configuration mode |
|---|---|
| 3 | Enter interface configuration mode |
| 4 | Enable EIGRP for IPv6 on the interface |
| Repeat steps 1-4 on all EIGRP for IPv6 interfaces | |
| 5 | Enter EIGRP for IPv6 router configuration modeNote: This is a global configuration mode command |
How does EIGRP for IPv6 differ from EIGRP for IPv4?
EIGRP for IPv6 advertises IPv6 prefixes/lengths, rather than IPv4 subnet/mask information. EIGRP for IPv6 uses the neighbor’s link-local address as the next-hop IP address; EIGRP for IPv4 has no equivalent concept.
How do we configure EIGRP?
How do you configure EIGRP in the Cisco IOS?
- 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.
Which command can turn off EIGRP for the ipv6 routing process?
Table 3-6 Commands Used in Example 3-20
| Command(s) | Description |
|---|---|
| ipv6 unicast-routing | Enable IPv6 routing |
| ipv6 router eigrp 1 | Configure EIGRP with AS number 1 |
| no shutdown | Enable the EIGRP process |
| show ipv6 protocol | Verify the EIGRP process has started (more on EIGRP verification/show commands in the next section) |
What is EIGRP protocol?
Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol that enables routers to exchange information more efficiently than earlier network protocols, such as Interior Gateway Routing Protocol (IGRP) or Border Gateway Protocol (BGP).
Does EIGRP work with IPv6?
The interfaces can be directly configured with EIGRP for IPv6, without the use of a global IPv6 address. There is no network statement in EIGRP for IPv6. The router ID needs to be configured for an EIGRPv6 protocol instance before it can run. EIGRP for IPv6 has a shutdown feature.
How do I verify EIGRP configuration?
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.
How do I change my EIGRP router ID?
The command syntax is:
- Router(config)# router eigrp autonomous-system.
- Router(config-router)# eigrp router-id ipv4-address.
- Router(config)# interface loopback number.
- Router(config-if)# ip address ipv4-address subnet-mask.
What is the command for EIGRP?
To configure the hold time for Enhanced Interior Gateway Routing Protocol (EIGRP) address-family, use the hold-time command in address-family interface configuration mode. To configure the default hold time, use the no form of this command.
What is the EIGRP protocol?
Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.
What is EIGRP router ID?
The EIGRP router ID comes from the highest IP address assigned to a loopback interface. If no loopback interfaces are configured, the highest IP address assigned to any other active interface is chosen as the router ID. No two EIGRP routers can have the same EIGRP router ID.
What are the 3 EIGRP tables?
EIGRP uses three tables: the neighbor table, the topology table, and the IP routing table. The neighbor table keeps state information regarding neighbors, and is displayed using the show ip eigrp neighbors command. EIGRP Update messages fill the routers’ EIGRP topology tables.
Does EIGRP use TCP or UDP?
EIGRP does not operate using the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). This means that EIGRP does not use a port number to identify traffic. Rather, EIGRP is designed to work on top of layer 3 (i.e. the IP protocol).
How do I know if EIGRP is working?
Why is EIGRP used?
EIGRP is used on a router to share routes with other routers within the same autonomous system. Unlike other well known routing protocols, such as RIP, EIGRP only sends incremental updates, reducing the workload on the router and the amount of data that needs to be transmitted.
What are EIGRP table types?
Which port does EIGRP use?
EIGRP has port No. 88 that runs on top of IP and is thus defined as a Transport Layer Protocol. BGP, Telnet, FTP, and other application-layer protocols lack a built-in reliability mechanism and rely on TCP (Protocol No. 6) at the Transport layer to ensure reliability.
What type of protocol is EIGRP?
How do I check my EIGRP route?
show ip route and show ip route eigrp for EIGRP Examples. 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.
How do I troubleshoot EIGRP?
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.
How many table EIGRP maintain?
three tables
Using the DUAL, EIGRP keeps track of three tables: neighbor table The neighbor table holds a list of all the routers EIGRP has established a neighborship with. topology table The topology table keeps track of the entire network topology.
What are the 5 types of OSPF packets?
Packet types for OSPF
- Hello packet. This packet is sent by the OMPROUTED server to discover OSPF neighbor routers and to establish bidirectional communications with them.
- Database description packet.
- Link-state update packet.
- Link-state request packet.
- Link-state acknowledgment packet.
What is EIGRP port number?
. 88
EIGRP has port No. 88 that runs on top of IP and is thus defined as a Transport Layer Protocol. BGP, Telnet, FTP, and other application-layer protocols lack a built-in reliability mechanism and rely on TCP (Protocol No. 6) at the Transport layer to ensure reliability.
