DHCP relay agent for IPv6

Enabling DHCPv6 Relay Agent Prefix Delegation notification on an interface

To set the number of delegated prefixes that can be learned at the interface level, use the ipv6

dhcp-relay maximum-delegated-prefixes command. This command limits the maximum number of

prefixes that can be learnt on the interface.

Brocade(config-if-eth2/1)# ipv6 dhcp-relay maximum-delegated-prefixes 4000

Syntax: [no] ipv6 dhcp-relay maximum-delegated-prefixes value

The value parameter is used to limit the maximum number of prefixes that can be delegated. The

range is from 0 to 20000. The default value is 20000.

Use the no ipv6 dhcp-relay maximum-delegated-prefixes command to set the parameter to the

default value of the specified platform. See Table 72 for more information.

Table 72 lists the default and maximum prefix values for different platforms.

Assigning the administrative distance to DHCPv6 static routes

To assign the administrative distance to DHCPv6 static routes installed in IPv6 route table for the

delegated prefixes on the interface, use the ipv6 dhcp-relay distance command at the interface

level. The administrative distance value has to be set so that it does not replace the same IPv6

static route configured by the user.

Brocade(config-if-eth2/1)# ipv6 dhcp-relay distance 25

Syntax: [no] ipv6 dhcp-relay distance value

The value parameter is used to assign the administrative distance to DHCPv6 static routes on the

interface. The range is from 1 to 255. The default value is 10. If the value is set to 255, then the

delegated prefixes for this interface will not be installed in the IPv6 static route table.

Use the no ipv6 dhcp-relay distance command to set the parameter to a default value of 10.
