Cisco Nexus 3000 Series NX-OS Unicast Routing Configuration Guide, Release 5.0(3)U2(2)
OL-25782-02
Chapter 4 Configuring EIGRP
Default Settings
• For graceful restart, an NSF-aware router must be up and completely converged with the network
before it can assist an NSF-capable router in a graceful restart operation.
• For graceful restart, neighboring switches participating in the graceful restart must be NSF-aware
or NSF-capable.
• Cisco NX-OS EIGRP is compatible with EIGRP in the Cisco IOS software.
• Do not change the metric weights without a good reason. If you change the metric weights, you must
apply the change to all EIGRP routers in the same autonomous system.
• Consider using stubs for larger networks.
• Avoid redistribution between different EIGRP autonomous systems because the EIGRP vector
metric will not be preserved.
• The no ip next-hop-self command does not guarantee reachability of the next hop.
• The ip passive-interface eigrp command suppresses neighbors from forming.
• Cisco NX-OS does not support IGRP or connecting IGRP and EIGRP clouds.
• Autosummarization is not enabled by default.
• Cisco NX-OS supports only IP.
Note If you are familiar with the Cisco IOS CLI, be aware that the Cisco NX-OS commands for this feature
might differ from the Cisco IOS commands that you would use.
