Enabling/Disabling Virtual Ip Address Pinging; Adding Or Deleting A Virtual Ip Address - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide

3.2.1 Enabling/Disabling Virtual IP Address Pinging

According to VRRP, users cannot ping the virtual IP addresses of standby groups and
as such, cannot determine whether an IP address is assigned to a standby group. If a
host on the network uses the same IP address of a standby group coincidently, all
packets in this network will be forwarded to the host improperly.
You can however use this command to enable or disable users to ping the virtual IP
addresses of standby groups.
Perform the following configuration in system view.
Table 3-1 Enable/disable virtual IP address pinging
Enable virtual IP address pinging.
Disable virtual IP address pinging.
By default, virtual IP address pinging is disabled.

3.2.2 Adding or Deleting a Virtual IP Address

You may assign an IP address on this network segment to a virtual router or standby
group or delete the specified or all virtual IP address from the virtual address list.
Perform the following configuration in interface view.
Table 3-2 Add/delete a virtual IP address
Add a virtual IP address.
Delete the specified or all virtual IP
addresses.
The standby group number virtual-router-ID is in the range 1 to 255. The virtual IP
address can be an unassigned address on the network segment to which the standby
group belongs, or the IP address of an interface in the standby group. In the latter case,
the router owns the IP address is called IP address owner.
The system creates a standby group the first time that you assign an IP address to it.
When you assign virtual IP addresses to the group after that, the system only adds the
addresses to the virtual IP address list of this standby group.
Note that before you can configure a standby group, you must create it by assigning an
IP address to it. Deleting the last virtual IP address from the standby group also deletes
the standby group. After that, all its configurations become invalid.
