Can't ping the bridge domain IP (gateway) from the APIC

[indira178]

Hi all,

I created the BD, EPG and add and static binding (vpc), endpoints were learn, however, the endpoints cannot ping the gateway, testing further, I cannot ping the gateway from the APIC either.

This is weird because I have the exact same config on the other DC and is working fine.

Do you have an idea what could be causing the issue? I've checked and all the L3 config, AEP seems to be fine (same than the other DC), I also try to delete everything and add it again with no luck!

Thanks in advance.

Hello Indira,

Can you please confirm the EP IP, subnet mask, and the BD settings defined along with the BD SVI defined. Are these EPs VMs, bare metal? 

Thanks!

the EP are connected to a vpc, the ips are the following:

10.185.87.11                              201 202     vpc Switch201-202_1-ports-      vlan-2762 
 10.185.87.12                              201 202     vpc Switch201-202_1-ports-      vlan-2762     

The BD settings:

  tenant Non-Production
    interface bridge-domain Non_Prod_BD
      description 'VLAN 2762 - 10.185.87.0/27'
      ip address 10.185.87.1/27 secondary scope public
      ip igmp inherit interface-policy NonProd_Tenant_IGMP_Policy tenant Non-Production
      exit
    exit

The EPs are baremetal. I found really strange as we have and active active config so the other DC has the exact same config and is working fine. Please let me know if you need any other info.

Thank you for your response.

What type of bare metal is this? Is it by any chance a Windows server? What load balancing option is configured for the NIC teaming?

[indira178]

I don't have the details of the server, there's other team configuring this. They reported they couldn't reach the gateway, I thought it could be their config as it happened before. However, I cannot ping from the APIC to the gateway IP.

Hello All,

This network is going via OOB connected to an MPLS in other country, the traffic is not going via ACI directly, making the ping not possible.

The issue was the network was being advertised via the MPLS and not permited to ping. The resolution was to stop advertising the network on the MPLS.

Thank you!
