[j-nsp] VMX to VMX traffic on ESXi

[serge vautour]

Hello,

I haven't had any replies in the Juniper VMX forum so I thought I'd try
here:

I have setup 2 VMX (each with a VCP & VPFE) on one ESXi host using Junos
VMX 15.1F4. Each VMX seems to be working fine on it's own. I can remotely
access the fxp0 interface.

I created a dedicated vswitch with promiscuous mode on for the GE
interface. I used this vswitch for the 3rd NIC on each VPFE. I did not
attach any physical NICs to the vswitch as I only want to use it for
VMX-VMX traffic. Each VMX sees all 8 GE with ge-0/0/0 being up. I configure:

user at LabVMX1> show configuration interfaces ge-0/0/0
description "Link to VMX2 ge-0/0/0";
unit 0 {
family inet {
address 10.5.5.0/31;
}
}

user at LabVMX2> show configuration interfaces ge-0/0/0
description "Link to VMX1 ge-0/0/0";
unit 0 {
family inet {
address 10.5.5.1/31;
}
}

I also added OSPF to each interface. VMX1 seems to work fine. It shows
in/out traffic. VMX2 only shows outbound traffic.

Using "monitor traffic interface ge-0/0/0" command I see:

VMX1:

14:56:57.489954 In IP 10.5.5.1 > 224.0.0.5: OSPFv2, Hello, length 56
14:57:02.079691 Out IP truncated-ip - 20 bytes missing! 10.5.5.0 > 224.0.0.5:
OSPFv2, Hello, length 60

VMX2:
14:57:48.925035 Out IP truncated-ip - 16 bytes missing! 10.5.5.1 > 224.0.0.5:
OSPFv2, Hello, length 56

14:57:58.487367 Out IP truncated-ip - 16 bytes missing! 10.5.5.1 > 224.0.0.5:
OSPFv2, Hello, length 56

VMX1 arp cache:

00:0c:29:a7:e9:09 10.5.5.1 ge-0/0/0.0 none

VMX2 arp cache is empty.

I never see any inbound packets on VMX2. I've tied ping same result. I
through this might be a broadcast/multicast problem so I tried configuring
static arp entries and then did a ping but this didn't help.

Any help would be appreciated.

Thanks,
Serge
