# Configuring IPv6 routing and ICMP

Use this procedure to enable IPv6 routing to route IPv6 traffic on the switch. IPv6 packets transport Internet Control Message Protocol (ICMP) error and information messages. Configure the rate, in milliseconds, at which ICMP sends messages to conserve system resources.

## Procedure steps

1. From the navigation tree, double-click IPv6.

2. Double-click IPv6.

3. To enable IPv6 routing, in the Forwarding box, select forwarding.

4. Configure the routing and ICMP parameters as required.

5. Click Apply.

## Variable definitions

The following table describes the fields of the IPv6 Globals tab.

Variable | Value
--- | ---
AdminEnabled | Configures IPv6 as administratively enabled or disabled.
OperEnabled | Indicates whether IPv6 is operationally enabled or disabled.
Forwarding | Configures whether this entity is an IPv6 router with respect to the forwarding of datagrams received by, but not addressed to, this entity. Select forwarding to act as a router. Select notForwarding to not act as a router. The default is notForwarding.
DefaultHopLimit | Configures the hop limit. The default is 30.
IcmpNetUnreach | If selected, enables the ICMP network unreachable feature. The default is disabled.
IcmpRedirectMsg | If selected, enables the ICMP redirect message feature. The default is disabled.
IcmpErrorInterval | Configures the interval (in milliseconds) for sending ICMPv6 error messages. The default is 1000 milliseconds. An entry of 0 seconds results in no sent ICMPv6 error messages.
IcmpErrorQuota | Specifies the number of ICMP error messages that can be sent during the ICMP error interval. A value of zero specifies not to send any. The default value is 50.
MulticastAdmin Status | Specifies the multicast administrative status. The default is false.
