VRRP Backup no ping and arp

I have 2 HP 5406zl Core Switches and a problem with vrrp.

From Core 1 I can arp to core2 but not ping anything. From Core2 I cannot even arp and ping fails.
I tried to clear arp cache with clear arp but still the same result.

CORE1# ping 10.1.31.253
Request timed out.

CORE1# sh arp vlan 130 IP ARP table - VLAN 130 IP Address MAC Address Type Port --------------- ----------------- ------- ---- 10.1.31.253 3464a9-4a2800 dynamic Trk1
----------------------------------------------------------------------------------------------
CORE2# ping 10.1.31.254
Request timed out.

CORE2# sh arp vlan 130

 IP ARP table - VLAN 130

  IP Address       MAC Address       Type    Port
  ---------------  ----------------- ------- ----



Between my 2 HP 5406zl Core Switches there is a trunk configured and I tagged all ports on both sides on trk1.
Then I setup a new /22 Vlan with an IP Address.

 

vlan 130
   name "computer"
   tagged Trk1
   ip address 10.1.31.254 255.255.252.0
   vrrp vrid 130
      virtual-ip-address 10.1.31.254
      advertise-interval 5
      priority 255
      enable
      exit
   exit

vlan 130
   name "computer"
   tagged Trk1
   ip address 10.1.31.253 255.255.252.0
   vrrp vrid 130
      virtual-ip-address 10.1.31.254
      advertise-interval 5
      enable
      exit
   exit

The sh vrrp config vlan 130 shows the following:

The counter on Backup Advertise Pkts Rx is increasing every few secondso on the backup VRRP.

Can someone help me fixing the problem?

Re: VRRP Backup no ping and arp

Hello ,

The Backup Advertise Pkts Rx is expected as these are the hello packets received from the Master.

Regarding the ping, I tried it quickly on my lab as i already had a setup . Mine works fine with your scenerio and i am able to ping.

I am running K.16.02.0021

However , you could try enabling the virtual-ip-ping from the global vrrp context and the vlan interface context.

<Global >

router vrrp

virtual-ip-ping

<VLAN context>

vlan 999

vrrp vrid 130

virtual-ip-ping

Is your network impacted due to this ? Because i see the VRRP is working fine as its receiving the hellp packets from the Master .

The standby does not need to respond to ARP unless the Master goes down.

 

Hope this helps :)

Hi

 

Is there any intermittent device between both 5400 switches..?

Re: VRRP Backup no ping and arp

Hello,

i enabled to ping command inside the vrrp configuration and it was enabled in global before we did anything.
I can see arp from Core1 to 10.1.31.253 but ping is not possible.
I cannot see any arp on Core2 on VLAN 130 and I cannot ping 10.1.31.254.

Re: VRRP Backup no ping and arp

Hello,

between Core 1 and Core 2 there is only a trunk which is directly connected. I don't see a intermittent device between them.
