Prerequisites for Implementing EIGRP on Cisco IOS XR Software
The following are prerequisites for implementing EIGRP on Cisco IOS XR software:
• You must be in a user group associated with a task group that includes the proper task IDs for EIGRP
commands. For detailed information about user groups and task IDs, see the Configuring AAA
Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration
Guide.
Restrictions for Implementing EIGRP on Cisco IOS XR Software
The following restrictions are employed when running EIGRP on this version of
Cisco IOS XR software:
• Only one instance of an EIGRP process is supported.
• Bidirectional Forwarding Detection (BFD) feature and the Simple Network Management Protocol
(SNMP) MIB are not supported.
• Interface static routes are not automatically redistributed into EIGRP, because there are no network
commands.
• Metric configuration (either through the default-metric command or a route policy) is required for
redistribution of connected and static routes.
• Auto summary is disabled by default.
• Stub leak maps are not supported.
• Authentication is not supported.
