• metric rib-scale—This command was introduced.
• metric—The picoseconds keyword was added.
• metric weights—Support was added for the k6 constant.
• show eigrp interfaces—The command output was modified to display relevant wide metric information.
• show eigrp neighbors —The command output was modified to display relevant wide metric information.
• show eigrp topology—The command output was modified to display relevant wide metric information.
• show protocols—The command output was modified to display relevant wide metric information.
If there is a combination of IOS and IOS-XR PE devices in the network, then the EIGRP wide metric
must be disabled in IOS-XR PE device. This is because the method of calculating metrics in L3VPN
design between IOS and IOS-XR.
Note
EIGRP Multi-Instance
The Enhanced Interior Gateway Routing Protocol (EIGRP) Multi-Instance feature allows multiple process
instances to handle different routing instances and service the same VRF. Each process instance handles the
routing instances configured under it. The multiple EIGRP process instance implementation allows to configure
the EIGRP using a virtual-name in addition to an autonomous-system number.
EIGRP Support for BFD
EIGRP supports Bidirectional forwarding detection (BFD) for link failure detection.
BFD provides low-overhead, short-duration detection of failures in the path between adjacent forwarding
engines. BFD allows a single mechanism to be used for failure detection over any media and at any protocol
layer, with a wide range of detection times and overhead. The fast detection of failures provides immediate
reaction to failure in the event of a failed link or neighbor.
How to Implement EIGRP
This section contains instructions for the following tasks:
To save configuration changes, you must commit changes when the system prompts you.Note
Enabling EIGRP Routing
This task enables EIGRP routing and establishes an EIGRP routing process.
