Investigate cisco switch redundancy #955

Closed naved001 closed 1 year ago

naved001 commented 1 year ago

We get the public network 129.10.5.0/24 from 2 cisco switches, but when either switch fails the network becomes unreachable.

I was mistaken, we get the NEU public network via one switch

interface Ethernet1/48
  description "port-channel to SFCORE-MGH-MDA-R6C23-1 eth2/6"
  switchport mode trunk
  switchport trunk native vlan 125
  switchport trunk allowed vlan 125,151
  no shutdown

The other switch carries these VLANs

version 7.3(11)N1(1)

interface Ethernet1/48
  description "port-channel to SFCORE-MGH-MDA-R6C23-1 eth2/5"
  switchport mode trunk
  switchport trunk allowed vlan 150,3800,3802

VLAN 3802 is the CSAIL public VLAN used for kaizen openstack floating IP (and RGWs).

There is something going on with OSPF routing that I don't fully understand yet.
