Unified ports on the Nexus 5500 platforms enable an interface to have one of the following characteristics depending on the licensing and pluggable transceiver installed: traditional Ethernet, Fibre Channel (FC), or. The behaviour is different again for Nexus 5000/2000 series switches, which we'll leave for now. This means that some OSPF routed traffic will traverse the vPC peer-link (even when no ports or links are failed). The OSPFv2 is configured across the previously configured vPC pair of the Nexus N93k and the N95k. router ospf 1 network 0. Conditions: NX router running stub no-summary OSPF AREA. First we enable the "feature ospf" and configure some basic OSPF commands and assign Area 0 to interface Eth2/1 on both N7K and assign Area 1. Whether there was a transit link failure or simply a stub link going up or down, OSPFv2 had to perform complete SPF calculation as this was reflected using the same event that would report a network. Telemetry commands. 0/24) as shown in Example of show ip route command output with multiple next-hop routes. Select Interface tab and click add.
