Nexus 5500 - inband via default vrf and out-of-band via management vrf

tin.ngo

Nexus 5548 with no layer 3 module.  Want to manage the device via 10.122.122.5 9 (inband) and 10.122.123.58 (out-of-band)

Currently i can get to the device using 10.122.123.58 via management vrf but can't get to 10.122.122.5 via default vrf.

A couple of questions please:

1) Is this design support? or do i need a layer 3 module + licensing to use the default vrf?

2) What does "pending" in the default vrf routing table indicate?

 

interface Vlan12
  no shutdown
  ip address 10.122.122.5/25

ip route 0.0.0.0/0 10.122.122.1


interface mgmt0
  vrf member management
  ip address 10.122.123.58/26

vrf context management
  ip route 0.0.0.0/0 10.122.123.1

 

sh ip route vrf all

what was the solution?

My problem was upstream so above is working fine.

You can manage the N5K via both default and management vrf without Layer 3 module.  Pending static route in the default vrf is just cosmetic.  I manage the N5K via default vrf and the management vrf is for peer-keep alive.  Hope that helps.
