ASR1000V causing duplicate ping packets

sharan
Level 1
Level 1

I just successfully installed csr1000v-universalk9.03.13.01.S.154-3.S1-ext.iso in a KVM cloud environment.

 

The virtual router has 2 interfaces, G1 is public internet, and G2 is private which connects to other servers.  The public facing interface works fine with absolutely no problems, but I am seeing latency on the inside interface and it causes duplicated packets as follows on all servers residing in the private network when performing ping tests:


64 bytes from 5.0.0.1: icmp_seq=48518 ttl=23 time=42479 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48518 ttl=22 time=42486 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48514 ttl=21 time=46490 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48514 ttl=20 time=46498 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48534 ttl=64 time=26551 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48534 ttl=63 time=26559 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48507 ttl=4 time=53553 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48507 ttl=3 time=53561 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48507 ttl=1 time=53569 ms (DUP!)
64 bytes from 5.0.0.1: icmp_seq=48513 ttl=18 time=47651 ms (DUP!)
From 5.0.0.3 icmp_seq=48513 Time to live exceeded

 

Has anyone seen this before?  If I reformat the asr1000v with Centos, there are no network issues, so I'm 100% certain it's not a physical or logical issue, but more specifically something to do with the router image.

 

Relevant config:

Interface GigabitEthernet1
 ip address dhcp
 negotiation auto
!
interface GigabitEthernet2
 ip address 5.0.0.3 255.255.255.0
 negotiation auto
