Communication Is Not Possible With The Vrrp Configuration Of Ipv4 Networks - Alaxala AX6700S Troubleshooting Manual

3.13.2 Communication is not possible with the VRRP configuration of IPv4
networks
If communication is not possible in a VRRP configuration, isolate the cause of the problem
according to the failure analysis method described in the following table.
Table 3-69 Failure analysis method for VRRP
No. Items to check and commands
1 On the Switch and remote devices
that make up a virtual router, check
the status of the virtual router, and
check whether only one device is the
master router and the others are
backup routers.
2 Execute the

VLAN to which the virtual router is
connected.
3 For the virtual routers of the Switch
and remote devices that make up a
virtual router, check whether only
one virtual router is the master
router.
4 Execute the
show vrrpstatus
command with the
parameter, and check whether the
primary virtual router that is followed
by other virtual routers has been
configured.
Action
For devices that make up a virtual router, if only one device is the
master router and the others are the backup routers, check the
following:
If there is no problem with the terminal settings and with the route
information of the devices on the communication path, go to No.

If the status of the virtual router is not correct, go to No. 3.

If the status of the physical port is Forwarding, check whether
the load of the routing destination network is high.
If only one virtual router is the master router, go to No. 10.
If the primary virtual router followed by other virtual routers has
been configured, go to No. 5.
detail
If the primary virtual router followed by other virtual routers has
not been configured, go to No. 6.
3 Troubleshooting Functional Failures During Operation
If terminals are connected directly to the virtual router not via
other routers, make sure the virtual IP address of the virtual
router is set as the default gateway in the network settings of
the terminals.
Check the route information of the devices on the
communication path that includes the Switch.
If the status of the physical port is Blocking,
communication might have been temporarily blocked due to,
for example, the topology change for STP. Wait a while, and
then make sure that the status of the physical port is
Forwarding. If you wait a while but the status of the
physical port is not Forwarding, check the configuration
and physical network configuration.
If the status of the physical port is down, the port is not
physically connected. Check whether connectors and
cables are connected correctly.
For AX6700S, AX6600S, or AX6300S series switches:
If multiple virtual routers are master routers, go to No. 4.
For AX3800S or AX3600S series switches:
If multiple virtual routers are master routers, go to No. 6.
